Low temperature gain-switched operation of non-cubic Cr2+,Fe2+:Zn1-xMgxSe (x ~ 0.2 and x ~ 0.3) single crystals in mid-infrared under different excitation wavelengths
Original language description
Two novel cryogenically cooled non-cubic wurtzite structure Cr2+,Fe2+:Zn1-xMgxSe (x ~ 0.2 and x ~ 0.3) single crystals co-doped with Cr2+ and Fe2+ ions with thickness of 2.5 and 5 mm, respectively, were investigated under two excitation wavelengths of the Q-switched Er3+:YLF (λ ~ 1.73 μm) and Er3+:YAG (λ ~ 2.94 μm) lasers. Absorption and fluorescence spectra, fluorescence lifetimes as well as laser output characteristics for both Cr2+ and Fe2+ doping ions were measured at 78 K. Both Cr2+,Fe2+:Zn1-xMgxSe laser systems were able to generate radiation from Cr2+ as well as Fe2+ active ions depending on appropriate pumping wavelength and a set of laser cavity mirrors. Moreover, Fe2+ ions mid-IR lasing using the Cr2+ -> Fe2+ ions energy transfer at ~4.57 μm and ~4.8 μm for magnesium content of x ~ 0.2 and x ~ 0.3, respectively were realized for ~1.73 μm Q-switched Er3+:YLF laser pumping. The results present an opportunity to develop novel mid-IR 4.4 – 4.9 μm coherent laser sources based on non-cubic AIIBVI matrices using direct Fe2+ ions pumping at ~2.94 μm as well as excitation via co-doped Cr2+ ions at ~1.73 μm.
