Mode-locked femtosecond laser with a rotary Nd:glass disk

摘要

We demonstrate here femtosecond pulses output from a rotary Nd:glass disk laser, mode-locked with semiconductor saturable absorber mirrors. We obtained an average output power of 0.66 W in cw operation and an average output power of 0.49 W with a duration of 324 fs in mode-locked operation in the case of an absorbed pump power of 7.3 W. To the best of our knowledge, it is the first time that sub-picosecond pulses have been obtained from rotary Nd: glass disk lasers. It shows a new concept for all-solid-state mode-locked glass lasers with high power. (C) 2019 Optical Society of America
