ABSTRACT:
A method of evaluating a non-linear optical crystal used for non-linear wavelength conversion of laser beam which enables the non-linear optical crystal to be evaluated before the crystal is actually used as a wavelength conversion element in order for the crystal to be constantly used for an extended time with a high conversion efficiency retained and without lowering in output when non-linear optical crystals for various non-linear wavelength conversions such as a CLBO crystal are used to convert laser beams, wherein the non-linear optical crystal is moved to changed a laser beam incident position to detect the output of a laser beam emitted from the non-linear optical crystal for each changing position.
