Dual-wavelength TEM01 mode passively mode-locked Nd:YAG laser with semiconductor saturable absorber mirror

摘要

A dual-wavelength TEM01 mode synchronous continuous wave passively mode-locked (CWML) Nd:YAG laser has been demonstrated for the first time to the best of our knowledge with a semiconductor saturable absorber mirror (SESAM) at 1319 and 1338 nm. The maximum average output power of 10.84 W was obtained at a 113.8 W absorbed pump power, corresponding to an optical-to-optical conversion efficiency of 9.5%. The dual-wavelength CW1141, pulses had a pulse duration of 35.1 ps at a repetition rate of 76 MHz. The beam quality was measured to be M-2 = 2.51. (C) 2019 Optical Society of America
