Abstract

Average power scaling of mid-infrared Optical Parametric Oscillators are presently limited by nonlinear material bulk absorption and resulting thermal gradients and thermally induced focusing and higher order aberrations. We discuss an optical correction scheme that corrects higher order aberrations typically present in gaussian intensity profile beams used for pumping OPO's to reduce the nonlinear dephasing by one- half. While correction of thermal focus has been shown to improve the power scaling in an OPO, further improvements can be made by correcting the remaining higher order aberrations. Such reduction in dephasing should significantly improve the power scaling potential of solid state lasers and OPO's.
