1.94 μm, 1.97 μm and 2.064 μm Wavelength Operation of CW and Passively-Q-Switched Tm3+:Lu2O3 Ceramics Lasers under In-Band Fiber-Laser Pumping

A Tm3+:Lu 2 O 3 ceramics laser in-band pumped by a fiber laser at 1.67 μm was operated in CW and Q-switched multi-wavelength regimes at 1.94 μm, 1.97 μm and 2.066 μm. The passive Q-switched mode of the ceramics laser was achieved using a Cr2+:ZnSe saturable absorber.
