The Fresnel number is a characteristic parameter for the characterization of the resonator diffraction losses. The diffraction loss curve of a diffraction loss and the relationship of the Fresnel number N is generally more complex, and often write the analytic expression and digital computer calculation. Therefore, usually the count results are plotted into a curve, which is called the diffraction loss curve. The picture of a confocal cavity and the circular cross section of circular cross section parallel to the curve of the planar cavity, 1. N greater the smaller the δ D; In the same N, the transverse mode the higher the ordinal number of δ D greater; in the same N and the same number of cross-motif confocal cavity is much smaller than the plane parallel to the cavity, which is due to concave mirror The convergence of the role of light is more concentrated in the center of sake. Huaye green laser pointer company has rich professional technical experience in optics.The one-way diffraction loss of the symmetric cavity TEM00 mode changes with the Fresnel number is drawn. In the same N, the closer the confocal cavity (g = 0), the smaller the diffraction loss. Mode volume of the fundamental mode volume in a model used to describe the spatial extent of the expansion mode in the cavity. Mode volume oscillation in this mode, the role of the number of excited particles, and thus, the output power. On the contrary, the mode volume is small, the output power is small. The volume of the fundamental mode varies with the cavity and g N parameters change.Huaye green laser pointer company has rich professional technical experience in machine. The structural parameters of the cavity; Fresnel number resonator theory analysis shows that, when considering the symmetric cavity (R1 = R2), the fundamental mode (TEM00) Gaussian beam waist of W0 can be expressed as follows: with the following properties: (1) mirrors radius of curvature R is increased, the fundamental mode waist W0 increases, thus the volume of the fundamental mode increases. Therefore, the parallel plane cavity larger mode volume. ② When the R value W0 with the cavity L changes there is a great value, we can draw the maximum conditions for L = R (confocal cavity). More than the nature of practical significance in the election mode technology. In addition, the transverse mode selection is also a necessary condition for single-frequency lasers required.

R&D strength.A diffraction loss and Fresnel number (1) the formation of the
light energy loss due to diffraction effect known as diffraction losses. (2) as
shown in the spherical confocal cavity, mirror on the fundamental transverse

introducing the parameters of the Fresnel number, which is defined as: a2 N = λL
one-way diffraction loss is expressed as: one-way diffraction loss is expressed
as: confocal cavity of the fundamental transverse mode, the diffraction loss is
only associated with the Fresnel number N, N greater the smaller the diffraction
loss. Different types of cavity and the cavity parameters, the diffraction loss
of the same. Usually when the resonator in the design, appropriate choice of the
cavity type and cavity parameters g, N can be the base mode output. Confocal
cavity (g = 0) ratio δ10/δ00 maximum, which seems to favor the election mode,
however, the fundamental mode of the confocal cavity loss δ00 and the loss of
the TEM10 mode δ10 are too small. Order to suppress the higher order mode, it is
necessary to reduce the cavity Fresnel number N N value decreases, the
fundamental mode volume is small, the output power decreased. Parallel plane
cavity, although the ratio δ10/δ00 δ00 and δ10 allow owners to choose the larger
value of N, the TEM10 mode can still not state of oscillation suppression, due
to their fundamental mode volume than Once a single transverse mode oscillation,
the output power may be high.Huaye green laser pointer company takes the
ISO9001 international quality system certification as its management system. (2)
aperture method for mold diaphragm method selected mode is most common, is also
very simple, just insert an appropriately sized holes in the cavity aperture can
suppress higher order transverse mode and base mode output.

With the extension of the laser welding machine pumped xenon lamp usage time
The power of negative feedback laser welding machine block diagram shown in
Figure 2. Figure 2 power block diagram of negative feedback laser welding
machine. Compared with the current negative feedback control using the negative
feedback of the laser power control accuracy of the output laser energy can be
greatly improved, in particular, which is suitable for mass production. Figure 3
is a United win laser 15W laser welding machine in the current negative feedback
and laser power fluctuations of the laser output energy in negative feedback
control of the state. This kind of green laser pointer is more suitable to the
customer.
Figure 3 Laser power of negative feedback and current negative feedback when the output laser energy. Can be seen from Figure 3, in approximately the same output power conditions, the negative feedback of the current energy instability is greater than 8%, while the energy instability of the negative feedback of the laser power output is less than 3%. With the extension of the laser welding machine pumped xenon lamp usage time, the electro-optical conversion efficiency of pumped xenon lamp will further reduce the current negative feedback condition, the output energy will be gradually reduced, quality control personnel often detect the output laser energy, thus increasing production costs. The laser ray color of green laser pointer can be chosen by the customer according to the need.
Negative feedback to the laser power, the system automatically output the size of the laser energy and real-time adjust the compensation pumped xenon lamp current size, so you can ensure that the output laser energy is always in a relatively stable range. In addition, the use of negative feedback control of laser power laser welding machine very easy to implement the waveform of the laser power control, In fact, for different materials, using different laser power waveform, you can make more beautiful the effect of welding, sometimes using traditional methods Welding can not the material also can get a better welding effect by changing the laser power waveform. Figure 4 is a butterfly laser welding in the optical communications industry and the respective welding results when the square wave and programming waveforms. The effective range of green laser pointer should be described in the technical parameters of green laser pointer .

The handy use of green laser pointer is the key characteristics of green

Control features: feedback control mode, the power waveform selection. Proofing, the optical properties of the welding machine can be determined in the initial pilot production can visually determine the effect of welding, so I will not, but focuses on the consistency of laser welding laser control features. Laser welding machine on the market from the control characteristics are divided into two categories: the current negative feedback and negative feedback of the laser power. The current negative feedback control of laser-pumped xenon lamp current so that each time a controlled manner to maintain a constant current of the xenon lamp. More bottle shape green laser pointer will be manufactured.
However, the laser output power and pumped xenon lamp current is not linearly proportional relationship with the extension of the pumped xenon lamp usage time, the electro-optical conversion efficiency is significantly reduced, it will cause the output laser energy is reduced, thus affecting the effect of welding consistency. The negative feedback of the laser power in the output of the laser cavity and a photoelectric detector, detected by the laser power and laser power required, and thus control of the xenon lamp pumping current size of a control method. The negative feedback of the laser power is divided into real-time negative feedback and non-real-time two negative feedback. Real-time negative feedback will be detected by the laser power in a pulse of laser power and the laser power required for comparison. The green laser pointer store will perform the promotion of green laser pointer .
Then control the xenon lamp pumping current size of a control method. The non-real-time negative feedback will be compared to the previous pulse detection laser power waveform and set the waveform, and then determine the next pulse laser-pumped xenon lamp current size of the control.
Control features: feedback control mode, the power waveform selection. Proofing, the optical properties of the welding machine can be determined in the initial pilot production can visually determine the effect of welding, so I will not, but focuses on the consistency of laser welding laser control features. Laser welding machine on the market from the control characteristics are divided into two categories: the current negative feedback and negative feedback of the laser power. The current negative feedback control of laser-pumped xenon lamp current so that each time a controlled manner to maintain a constant current of the xenon lamp. More bottle shape green laser pointer will be manufactured.
However, the laser output power and pumped xenon lamp current is not linearly proportional relationship with the extension of the pumped xenon lamp usage time, the electro-optical conversion efficiency is significantly reduced, it will cause the output laser energy is reduced, thus affecting the effect of welding consistency. The negative feedback of the laser power in the output of the laser cavity and a photoelectric detector, detected by the laser power and laser power required, and thus control of the xenon lamp pumping current size of a control method. The negative feedback of the laser power is divided into real-time negative feedback and non-real-time two negative feedback. Real-time negative feedback will be detected by the laser power in a pulse of laser power and the laser power required for comparison. The green laser pointer store will perform the promotion of green laser pointer .
Then control the xenon lamp pumping current size of a control method. The non-real-time negative feedback will be compared to the previous pulse detection laser power waveform and set the waveform, and then determine the next pulse laser-pumped xenon lamp current size of the control.

four-in-one green laser pointer
The green laser pointer company is specialized in all kinds of gift and
four-in-one green laser pointer .General understanding), ultrashort pulse
compression techniques (general understanding of the general knowledge of
ultrashort light pulses focused by a high peak when the transmission of
ultrashort light pulses in the medium, when the transmission of ultrashort light
pulses in the medium power density, high peak power density, therefore, the
transfer process usually show nonlinear effects, such as self-phase modulation
effect, self-focusing effect, the light sensor birefringence effect and other
effects, such as self-phase modulation effect focusing effect, the light sensor
such as birefringence effect in these nonlinear effects, the nonlinear effects
of the refractive index is the most basic of these nonlinear effects, the
nonlinear effect of the refractive index is the most basic is the additional
refractive index change caused by the optical field, is the additional
refractive index change due to light field, it is determined by the optical
pulse envelope function of time, therefore, taking into account the nonlinear
refractive index effect, a function of time, green laser pointer company owns
an employee team with high quality. therefore, take into account the nonlinear
effects of the refractive index, light pulses in different parts of the
refractive index change caused by (1) faster when the n2 relaxation time Tr is
much lower than the pulse width τp τp << Tr is much lower than the pulse
width τ is a transient response process can be written as: This is a transient
response, △ n (t) can be written as: can be written as △ n (t) = n2 is caused by
I (t) pulse of all parts of the additional phase change: Pulse all parts of the
additional phase changes as follows: k is the wave vector, L is the light pulse
in the length of the transmission medium.

The driving frequency of the controller can automatically match the cavity frequency. (2) use of the saturable absorber can also start the self-clamping the use of the saturable absorber can also start from the mode-locking of Ti: S laser.The green laser pointer company promises to provide high-quality products as well as high-quality service. Ti: S laser lasers. Laser laser cavity insert a saturable absorber body (such as the cavity insert a saturable absorber, such as HITCI), changing the dye concentration until the final shape into a mode-locked pulse width and average power has nothing to do with the dye into the mode-locked pulse pulse width and average power has nothing to do with the dye, and pulse just to establish the time the dye concentration (the higher the concentration, the shorter setup time by the impact of the higher the concentration of the dye concentration, the establishment of the shorter time), and remove the dye spray concentration the greater the membrane device can produce a self-locking. The membrane device can produce a self-locking. This shows that the role of the saturable absorber is just the introduction of the weakest modulation to start the self-clamping. Modulation to start the self-clamping. (3) quantum well reflector coupled cavity to start self-locking chess. Xinya green laser pointer company locates at the waterside in beautiful and wealthy Hangzhou.Active chamber and auxiliary chamber should be made to start a self-locking chess quantum well reflector coupled cavity. Quantum well reflector coupled cavity starts from lock chess low degree of coupling (the lower the degree of coupling of R L> 90%), the output mirror is replaced by a half-wave plate polarization minutes% variable beam splitter The output coupler. Beam consisting of a variable output coupler. (4) the use of the vibration mirror to start, a linear external cavity or direct vibration mirrors (usually start to use vibration mirror, an endoscopic linear external cavity or direct vibration generally start for the full use of vibration mirror reflector) frequency 25Hz, the amplitude is less than the reflector, frequency, amplitude less than 0.5mm, enables: S Laser continuous shape, can make a Ti: laser by successive state to enter the state of the self-locking. State to enter the self-locking state.
