✦ Synopsis

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 output and a narrow linewidth less than 0.3 nm FWHM are achieved. Slope = 39.6% Slope = 37.4%

We have demonstrated a simple and compact tunable dual-wavelength Yb 3+ :KGd(WO4)2 (Yb:KGW) laser. The laser is diode pumped through an optical bifurcated fiber and an adjustable beamsplitter. Thanks to two transversally chirped volume Bragg gratings (TCVBG) used as output couplers, the frequency di
