Abstract :
Summary form only given. We have demonstrated a novel laser integrated with a coupled tandem optical parametric oscillator (LICTOPO) configuration, which combines the intracavity OPO with a coupled tandem OPO. It takes advantages of: 1) Nd:YAlO/sub 3/, provides simple configuration for generating high power linearly polarized laser for pumping OPO; 2) a diffusion bonded walk off compensated (DBWOC) scheme reduces the aperture effect due to Poynting´s walkoff in the critically phase-matched parametric generation, as well as eliminates optical losses and need for alignment of crystals; 3) CTOPO makes use of recycling effect of nondepleted 2-/spl mu/m. All these result in the compactness and potential high conversion efficiency for mid-IR generation.
