Abstract
We present a laboratory model of a Q-switched Nd:YVO 4 laser with thermal effects compensation dedicated as a laser head for marking devices. Theoretical analysis on thermal effects were performed and resonator parameters were optimized. For 10 kHz repetition rate we obtained about 0.25 mJ of pulse energy corresponding to about 45 kW of peak power with slope efficiency 14%. M 2 parameter was 1.6. Full Text: PDF References J. E.
