Tempest Laser

Compact flashlamp pumped, Q-switched Nd:YAG laser system

The Tempest is a compact, pulsed Nd:YAG laser system delivering maximum performance in a compact, inexpensive platform. Designed with scientific applications in mind, the Tempest is easy to use and readily adaptable to specific requirements. Its proven resonator design is robust and provides superior beam pointing and energy stability with minimum beam divergence. With four available output beam wavelengths and a wide range of repetition rates (with single-shot, burst and continuous modes), the Tempest provides a complete solution for many applications.
