Some optical properties of KTP, LiIO/sub 3/, and LiNbO/sub 3/

Measurements of the absorption coefficient for KTP, LiIO/sub 3/, and LiNbO/sub 3/ are discussed. The variation of the refractive index with temperature has been measured for KTP and LiIO/sub 3/. It is necessary to know both the absorption coefficient beta and the variation in the indexes of refraction with temperature change dn/dT to determine the average power limit of a nonlinear interaction. With the dn/dT information, it is also possible to estimate the temperature half width of any nonlinear interaction by calculating the variation of the phase-matching condition with temperature.<
