The Influence of Cr2+ to Fe2+ Ions Concentration Ratio on the Cr, Fe:Zn1-x MnxSe (x ~ 0.15) Laser Properties Excited via Cr2+ -> Fe2+ Energy Transfer

Popis výsledku v původním jazyce

In this work the results of research of an optimal concentration ratio of Cr2+ and Fe2+ co-doped active ions for more efficient Cr2+ -> Fe2+ ions energy transfer in a chosen Zn1-xMnxSe (x ~ 0.15) host material are presented. Three cryogenically cooled Cr2+,Fe2+:Zn1-xMnxSe (x ~ 0.15) single crystals with the same thickness of ~2.7 mm and with different doping ratios of Cr2+ and Fe2+ ions of ~1:1, ~2:1, and ~3:1 were investigated under Q-switched Er:YLF laser excitation (wavelength: ~1.73 μm, pulse energy: ~10 mJ, pulse duration: ~150 ns). The temperature dependence of the absorption and fluorescence spectra, the fluorescence decay time as well as the laser output characteristics were measured. The Fe2+ ions maximum laser output of ~50 μJ at the wavelength range of ~4.25-4.42 μm was obtained with the crystal sample for which the active ions ratio was ~2:1. A further increase of the chromium ions amount (Cr2+:Fe2+ ~ 3:1) led to worse results. Using appropriate resonator cavity mirrors, the samples were also able to generate the ~2.35-2.45 μm laser radiation from Cr2+ ions. The laser output beam spatial profiles were close to Gaussian in all cases. In summary, an optimized compact source of mid-infrared ~4.25-4.42 μm (Fe2+) and ~2.35-2.45 μm (Cr2+) of Cr,Fe:Zn1-xMnxSe (x ~ 0.15) crystal pumped via Cr2+ ions by the ~1.73 μm radiation is described.
