2.3-and 4.4-mu m Lasing in Cr, Fe:Zn1-xMnxSe (x=0.3) Single Crystal Pumped by Q-Switched Er:YLF Laser at 1.73 mu m
Original language description
Novel Cr(2+)and Fe2+ co-doped Zn1-xMnxSe (x= 0.3) crystal with Cr2+ to Fe2+ ions concentration ratio of about 1 : 2 (both doping ions concentration were at the similar to 10(18)cm(-3) level) with a good optical quality was synthesized. Under pumping by a Q-switched Er:YLF laser at 1.73 mu m, the oscillations of Cr(2+)ions at 2.3 mu m as well as Fe(2+)ions at 4.4 mu m were realized. Both regimes, i.e. intracavity pumping of Fe(2+)ions by Cr2+ ions as well as excitation through the Cr2+-> Fe2+ ions energy transfer mechanism, were demonstrated. The output energy for Cr2+ ions lasing at 2.3 mu m was up to 900 mu J while Fe(2+)ions lasing at 4.4 mu m reached up to 60 mu J in the intracavity pumping mode. In the Cr2+-> Fe2+ energy transfer mode, the maximum output energy was 20 mu J at 4.4 mu m. Laser generation at 2.3 mu m was observed up to 340 K while Fe(2+)ions oscillations stopped for temperatures above similar to 150 K. The Fe(2+)ions oscillation wavelength was observed to shift with temperature increase from similar to 4.4 mu m at 78 K to similar to 4.5 mu m at 150 K. The Fe(2+)ions output pulses were quite stable in amplitude and temporal domain in both excitation modes with beam profile close to the fundamental transversal mode.
