Diode-pumped cryogenic Tm:LiYF4 laser
Proceedings of SPIE 11033, 11 (2019)

Abstract: We present the absorption spectroscopy and continuous -wave laser operation of Tm:YLF at cryogenic temperatures. At 100 K, a maximum output power of 2.55 W corresponding to a maximum slope efficiency of 22.8% is obtained using 15% output coupling transmission. The output laser wavelength is centered at 1877 nm for Ellc.
