The MagicPRISM is a compact, motorized optical parametric oscillator (OPO) module with a conversion efficiency as high as forty percent. The Ring-Cavity design is configured such that the pump and the OPO beams travel in the same direction. Two nonlinear crystals are positioned on a computer controlled, motorized rotation stage to acheive tuning. The pump beam is coupled into the Ring-Cavity and the signal/idler beams are coupled out of the ring cavity by a coated beam splitter. These design attributes produce highly stable and efficient output. The MagicPRISMTM OPO is offered as a stand-alone accessory to be pumped by the end-user’s laser.
