Paper Abstract

High beam quality pulsed Q-switched Nd:YAG solid-state laser 450m/s high speed online laser drilling and marking system is reported. By PCL-836(A) realizing the control of laser power supply, AQ-switcher and two-dimension scanner. Synchronizing pulsed laser and AQ-switcher through the delay of industry computer, and realizing short pulsed width for laser drilling, long pulsed width for laser marking through setting the releasing time of laser power supply. And adopting the two-dimension scanner to catch up with the high speed moving thin steel, which keeps the laser and steel relatively inaction. Drill at different positions of the moving steel, and use the pinhole to test the drilled holes.
