Optical Parametric Oscillator Laser System Pumped by Another Laser with Two Mutually Orthogonal Polarizations

摘要

PURPOSE: An optical parametric oscillator laser that uses a pumping light which consist of orthogonal two polarized lights is provided to amplify the output of a laser beam or output a laser beam having different wavelengths while minimizing the energy loss. CONSTITUTION: The pump light of a DPSS laser(1) is classified into a penetrated and polarized pump light(11) and a reflected and polarized pump light(12). An OPO laser beam having different wavelengths is outputted through an OPO(2) that satisfies a non-linear optical phase matching condition by using the split pump lights as a source.
