ＫｒＦやＡｒＦエキシマレーザ等の紫外線波長域のパルスレーザ光を、１ｍＪ／ｃｍ^2 ／パルス〜５０ｍＪ／ｃｍ^2 ／パルスのエネルギー密度で１０^4 〜１０^7 のパルス数照射した後に、１５０ｎｍ〜３００ｎｍの波長域における内部透過率を測定して紫外線耐久性を評価する。例文帳に追加

Fluorspar is irradiated with pulse laser beam with an ultraviolet wavelength region such as KrF or ArF excimer laser under such a condition that energy density is 1-50 mJ/cm2/pulse and the number of pulses is 104-107 and, thereafter, the internal transmissivity of fluorspar within a wavelength region of 150-300 nm is measured to evaluate the ultraviolet durability of fluorspar. - 特許庁
