Lee Laser (Orlando, FL) has developed a new, 800-Watt CW Nd:YAG laser that is capable of Q-switched performance in excess of 600 watts average output power at a 10-kHz pulse rate. The short pulse width capability is less than 70ns at 10 kHz without risk of damage to the internal optical elements. Pulse instability less than 8 percent peak-peak has been demonstrated. The laser’s electrical power consumption is 10 kW. Applications include deep marking and engraving, cutting of hard materials, flat-panel display (FPD) manufacture, and laser patterning for LCD manufacture.
