Abstract

PURPOSE:To prevent the evaproation of a metal container due to the irradiationo of laser beam, by previously arranging the protective material which is hard to dissolution-evaporate just below the additional mass on a crystal vibrator to which frequency-adjusting laser beams are caused to strike.
