YSGG:Cr:Nd laser with adaptive resonator

摘要

Abstract: YSGG:Cr:Nd laser adaptive resonator, adjusted to laser rod thermooptical distortions by means of hydraulically controlled HR flexible mirror, was developed and investigated. Lasing with output power of 27 W and with more than twice improved divergence of 9 mrad was demonstrated during the thermal lens correction. A high optical quality metal flexible hydraulically-controlled HR mirror with a wide range of a focal length alteration is proposed to correct a laser rod thermal lens.!10
