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