A Narrow Linewidth Continuous Wave Tm:YLF Laser with a Volume Bragg Grating. Issue 209 (23rd July 2020) - Xinyu, Chen
Abstract: We report a narrow linewidth continuous wave Tm:YLF laser with a Volume Bragg Grating. The Tm:YLF laser was operated at 1908.1 nm with FWHM of 0.14 nm. The maximum output power of 15.5 W with the absorbed pump power of 37.6 W, corresponding to the slope efficiency and optical-to-optical conversion efficiency were 46.5% and 41.3%, respectively.
