METHOD FOR EVALUATING LASER IRRADIATION RESISTANCE OF ORGANIC OPTICAL CRYSTAL AND EVALUATED ORGANIC OPTICAL CRYSTAL

摘要

PPROBLEM TO BE SOLVED: To establish a method for preliminarily easily and simply evaluating the laser irradiation resistance of an organic optical crystal in a non-destructive manner in order to irradiate the organic optical crystal with a laser beam to continuously use it, and the organic optical crystal having laser irradiation resistance evaluated by the evaluation method. PSOLUTION: The evaluation method for determining the presence of the laser irradiation resistance of the organic optical crystal by the diffractive analyzing process before the organic optical crystal is irradiated with the laser beam. Further, the organic optical crystal having laser irradiation resistance evaluated by the evaluation method is easily and simply provided to a wide field in a non-destructive manner.
