Název v původním jazyce
4.7 – 5.1 μm Lasing in Cr2+,Fe2+:Zn1-xMnxSe (x ~ 0.4) Single Crystal under 1.73 μm and 2.94 μm Pumping
Popis výsledku v původním jazyce
There is a continuous demand on a development of a laser system based on Fe2+ ions operating farther in the mid-infrared spectral range of 4.5–5.5 um coherently pumped by a convenient coherent source. In this work, results obtained with the Cr2+,Fe2+:Zn1-xMnxSe (x~0.4) single crystal pumped by two different electro-optically Q-switched lasers are presented and compared. Cr2+ and Fe2+ fluorescence and absorption spectra as well as fluorescence lifetimes were measured together with the laser output characteristics. Er:YLF laser excitation at 1.73 um followed by the Fe2+ ions laser oscillation via the Cr2+,Fe2+ ions energy transfer and Er:YAG laser direct excitation of Fe2+ ions at 2.94 um are presented. Both realized pumping resulted in the laser oscillation in the range of 4.7–5.1 um.
