2.5 µm and 4.5 µm lasing in Cr2+,Fe2+:Zn0.81Mg0.19 Se single crystal under 1.73 µm Q-switched Pumping via Cr2+ -> Fe2+ Energy Transfer
Original language description
Since the discovery of Fe2+ ions-based lasers in the 1990s, there has been a growing interest for using 4–5 um laser radiation for mid-infrared (IR) laser applications. There is a demand for a development of such compact laser system coherently pumped by a convenient laser source. In this work, according to author knowledge, the mid-IR 4.55 um laser oscillation of the novel Cr2+,Fe2+:Zn0:81Mg0:19Se laser active material pumped by a Q-switched Er:YLF laser at 1.73 um via the Cr2+ - Fe2+ ions energy transfer is reported for the first time (with output coupler OC1). Cr2+ ions laser oscillation at 2.5 um under 1.73 um excitation was also achieved with an output coupler OC2. Results obtained were compared with the direct excitation of the Fe2+ ions at 2.94 um by a Q-switched Er:YAG laser.
