Nd:YAG laser with mode locking using a travelling-wave acousto-optic modulator and spherical mirror

摘要

The results of an experimental investigation into the lasing properties of a diode-pumped Nd:YAG laser with mode locking using a spherical mirror and a travelling-wave acousto-optic modulator are presented. The properties of the diffracted radiation coupled out of the cavity by an acousto-optic modulator are measured in the case of a compact cavity and when losses similar to the transmission of the output mirror are introduced into the cavity. The effect of an additional cavity for reintroducing diffracted beams back into the laser cavity is also considered. (C) 2020 Optical Society of America
