Overview
Photonics Industries’ DM1 Series Nd:YLF and Nd:YAG green nanosecond lasers combine remarkably high pulse energies (up to 100 mJ) or high average powers (up to 200 W) with a simple, rugged, and efficient form factor, all from one fully independent laser resonator. Dual Head configurations can go up to 200 mJ of pulse energy or up to 400 W of power. The proprietary single laser resonator design[1] ideally fulfills the needs of both research and industry, from PIV research, to providing the necessary high energy for laser thermal processing or annealing applications in an industrial, compact form factor.
