The Opolette is an integrated, turn-key tunable laser system. It is the most compact system of its kind with a footprint of only 7x12". All system components, including the pump laser, the OPO, and optional UV modules are mounted on a single, hermetically sealed, optical frame.The user-friendly software provided with the system enables easy access to all the system functions. The patented OPO is a Double Resonance Oscillator (DRO) as well as a Double Pass Oscillator (DPO), resulting in high conversion efficiency, walk-off and beam steering cancellation, and excellent pointing stability.
