Abstract
We demonstrated a dual-wavelength Tm,Ho:LuLiF4 laser operating at 1895nm and 1950nm by adjusting the pitch angle of the output coupling mirror. With a X-type four-mirror cavity, a total output power of 575 mW is achieved at an incident pump power of 2.1 W, which corresponding slope efficiency is 27.95% and the threshold power is low to 110 mW. The dual-wavelength laser is very useful for the generation of coherent light source in terahertz band.
