Fe:ZnMnSe laser active material properties at room and cryogenic temperature

Original language description

Fe:Zn(1-x)Mn(x)Se solid solution spectroscopic and laser properties were investigated in the temperature range 80290 K. Two novel samples with different zinc - manganese (Zn-Mn) ratio described by the Mn content x (0.1 or 0.2) were used and the results were compared to the known Fe:ZnSe crystal. The samples had a broad absorption spectra with the maximum around 3 mu m and therefore an Er:YAG laser (2.94 mu m, 10 mJ, 120 ns) was used as a pump radiation source. The Fe:ZnMnSe fluorescence spectra are generally broad in the range 3.5 - 5.5 mu m. In the case of Fe: ZnMnSe x = 0.1, the fluorescence spectrum at 290 K is ranging from 3.5 to 5.5 mu m. Lowering the temperature down to 80 K lead to the spectral narrowing mainly in the mid-IR part, but the fluorescence is still up to 5 mu m at 80 K. In the case of Fe: ZnMnSe x = 0.2 the fluorescence is shifted towards mid-IR up to 5.2 mu m even at 80 K. The fluorescence lifetime decreases from tens of us at 80 K down to 1 us at 240 K. The laser oscillations were successfully achieved with both novel Fe: ZnMnSe crystals in the temperature range 80-290 K. In the case of x = 0.1, the central wavelength was similar to 4.2 mu m at 80 K and the temperature increase up to 290 K led to almost linear increase of the wavelength up to similar to 4.75 mu m. The tendency was similar in the case of Fe: ZnMnSe x = 0.2: the output wavelength increased from similar to 4.3 mu m up to similar to 4.8 mu m with the temperature increase from 80 to 290 K. The laser spectral linewidth was about 300 nm. In comparison with the Fe:ZnSe crystal, the laser output wavelength shift toward mid-IR region without any spectrally tunable element in the laser cavity can be clearly observed.
