Abstract

Absorption and luminescence properties of Fe:ZnSe and Fe:Cr:ZnSe crystals in the middle infrared spectral range were studied at room and low temperatures. Room temperature emission cross section of ⁵T₂->⁵E transmission of iron ions was estimated from spectroscopic measurements. Middle infrared emission of Fe²⁺ in ZnSe was studied under three different regimes of excitation: direct optical (2.92 μm) excitation of ⁵T₂ first excited state of Fe²⁺, excitation via 5E level of Cr co-dopant (1.56 μm), and excitation via photo-ionization transition of Fe²⁺ (0.532 μm). For the first time the energy transfer from Cr²⁺ (⁵E level) to Fe²⁺ (⁵T₂ level) under 1.56 μm wavelength excitation was observed and resulted in simultaneous room temperature emission of Fe:Cr:ZnSe crystal over ultra-broadband spectral range of 2-3 and 3.5-5 μm. We also report the first observation of middle infrared emission at 4.5 μm induced by 2+->3+->2+ ionization transitions of iron ions in Fe²⁺:ZnSe. The first room temperature gain-switched lasing of Fe:ZnSe crystal at 4.4 μm wavelength was demonstrated. Room temperature tunable oscillation of Fe:ZnSe crystal over 3.9-4.8 μm spectral range was realized.
