Paper Abstract

Thermally induced rupture of a nonlinear crystal is the primary limiting factor to the attainment of High average power (HAP) in an optical parametric amplifier (OPA). In this paper, HAP scaling behavior in an OPA is addressed in detail by combining thermally induced phase mismatching with thermally induced rupture. Expressions for thermally induced stress are derived and analyzed that can give directions for a HAP-OPA design. When an OPA generates the maximum average output power, the dependence of flaw size on thermo optical material parameters of nonlinear crystals is obtained that is very useful for surface processing, material selecting, properties improving of a nonlinear crystal and new HAP nonlinear crystals developing.
