Abstract
A method for thermally stabilizing an optical parametric oscillator (OPO)to maintain constant optical path length for stable high power output places a beam dumpoutside an OPO cavity. The OPOhas a nonlinear crystalwithin cavityfor splitting a single input pump beaminto lower energy signal and idler beams. The method includes providing a cavity exit port for unconverted pump and generated idler beams, and absorbing unconverted beams in beam dump. The method includes athermalization by actively cooling surfaces used as an optics mounting base, and athermalization by constraining the size of cavityby using thermally stiff members, guiding pins or rails, or by using bimetallic materials with different expansion.
