A diode pumped tunable single-frequency Tm:YAG laser using twisted-mode technique

摘要

A diode pumped tunable single-frequency Tm:YAG laser using the twisted-mode cavity is reported. The maximum single-frequency output power is 514 Mw with a slope efficiency of 9.7%. The wavelength tuning range from 2011.587 nm to 2016.065 nm is achieved by tuning the obliquity of a 1-mm-thick etalon. The single frequency laser has a beam quality of M~2 <1.3 at the maximum single-frequency output power.
