green laser pointer company provides packaging service

This green laser pointer company is deeply trusted by customers at home and abroad.Cavity length automatic compensation system block diagram shown in Figure 4 cavity length automatic compensation system block diagram shown in Figure 4-9 plus a DC voltage piezoelectric ceramics: PZT plus a DC voltage: the initial frequency of the piezoelectric ceramic ν0 need to add a frequency of f (piezoelectric ceramics on the need to add a frequency (about lkHz), only slightly (only a few tenths of volts) AC lkHz) rate is very small (only a few tenths of volts) signal, this information known as the "search signal" signal, this signal is called a "search signal" Figure 4-8 Lamb dip method the basic structure of the laser frequency stabilization Figure 4-9 Block diagram of Lamb dip frequency stabilization method 13 Lamb dip frequency stabilization method in Figure 4 -10 schematic diagram for the frequency stabilization. Products from this green laser pointer firm are various in style.Schematic diagram for the frequency stabilization. Schematic diagram for the frequency stabilization, if for some reason (such as temperature so that elongation elongation, if for some reason such as temperature) so that L elongation, cited for example, temperature? From side to laser frequency ν by the ν0 A, P and? ν of the opposite phase, if for some reason (such as temperature decreases to reduce the shortening, if for some reason such as temperature decreases) the L shortened, such as temperature decreases lead? from the laser frequency deviation from the ν0 to νB, P and? ν exactly the same as the phase around the center frequency ν in both the center frequency ν less than ν in the vicinity of ν0, whether ν is less than or greater than ν ν0 its results are increased to increase the output power P, is greater than ν0, Products from this green laser pointer company are novel in shape and unique in design.The result is the output power increases, but at this time? P will change the frequency and time? will change the frequency 2f will note the first frequency, laser excitation power is regulated and steady flow. First, the laser excitation power is regulated and steady flow. Second, second, the atoms of different isotopes of neon lines have a center frequency difference. A certain frequency difference. Thirdly, the frequency stability of the center of both sides of the Lamb dip and the slope of the size. Side of the slope of the size. 14 Figure 4-10 Schematic frequency stabilization (4-11) different isotope effects on the Lamb dip saturation absorption frequency stabilization 4.2.4 saturation absorption frequency stabilization of the signal device shown in Figure 4-12. As shown. Saturation absorption frequency stabilization device as shown in Figure 4-12 indicate saturation absorption frequency stabilization 4-12 Figure 4-13 Schematic of the absorption curve of the absorption medium and laser output power curve of the Lamb dip is similar, That has laid firm foundation for the green laser pointer company in this industry.with the laser output power curve of the Lamb dip is similar to the absorption in the absorbing medium also has an absorption curve of depression, as shown in Figure 4-13 also has an absorption depression, as shown due to absorption of low pressure inside the tube, a small collision broadening , due to absorption of low pressure inside the tube, the collision broadening is small, so the absorption line center of the depression formed in the laser tube than the width of the Lamb dip is much narrower. Into a depression in the Lamb dip than the laser width is much narrower.
