A Family of Small, Cost-Effective, Q-Switched Nd:YAG Laser Systems Designed to Support a Wide Range of Industrial, Scientific and Educational Applications.

Polaris systems are high-performance, flexible and extremely compact flash-lamp pumped Nd:YAG laser systems. They feature exceptional beam quality and energy stability in a small, easy-to-set-up, easy-to-operate package. The available range of wavelengths, energy levels and repetition rates provide great flexibility.
