High power simultaneous dual-wavelength CW and passively-Q-switched laser operation of LD pumped Tm:YLF at 19 and 23 µm

Abstract

-single-doped solid-state laser at 1.9 and 2.3 µm. The higher optical conversion efficiency, smaller wavelength competition effect and simultaneous dual-wavelength output make this Tm-doped solid-state laser have potential application in medical surgery.
