✦ Synopsis

Stable wavelength, narrow linewidth continuouswave (CW) Tm:YLF laser with double Fabry-Perot etalons by using the dual-end-pumping configuration is presented. We achieved the maximum output power of 14.0 W when the incident pump power of 56.3 W, corresponding to the optical-tooptical conversion efficiency of 24.9% and slope efficiency of 32.2%. The Tm:YLF laser operats at 1907.7 nm with FWHM of approximately 0.15 nm. The shift of the laser wavelength was only 0.2 nm with the incident pump power from 20.6 W to 56.3 W.

Intensity, a.u. 10.

We report a diode-pumped CW Tm:YLF laser at room temperature with a volume Bragg grating (VBG) instead of the conventional mirror. The Tm:YLF laser operated at 1909.5 nm with output power 6.0 W. The optical-to-optical conversion efficiency is 25.7% and slope efficiency is 37.4%. Also, a stable outpu
