Diode-pumped continuous-wave Nd:GSAG lasers operating at 1.4 μm
We report a laser diode-pumped continuous-wave (CW) Nd:GSAG lasers operating at 1.4 μm for the first time. By rotating the intracavity Lyot filter, three tuning wavelengths at 1402, 1426 and 1440 nm were realized, respectively. At an incident pump power of 20 W, the maximum output power of 2.3 W at 1440 nm was obtained with the slope efficiency of 13.6 % and the optical conversion efficiency of 11.5 %. Besides, simultaneous dual-wavelength lasers operating at 1402 and 1426 nm, 1402 and 1440 nm, 1426 and 1440 nm were also obtained, respectively. At an incident pump power of 20 W, the total output power of the1426 and 1440 nm wavelengths was 1.84 W with the total slope efficiency of 11.8 % and the total optical conversion efficiency of 9.2 %. To the best of our knowledge, this is the first work realizing dual-wavelength laser operating at 1.4 μm in Nd-doped crystals.
