Spectral and lasing characteristics of Fe:Cd1-xMnxTe (x = 01 – 076) crystals in the temperature range 77 to 300 K

The spectroscopic and laser properties of Fe:Cd1-xMnxTe with a various amount of manganese Mn (x = 0.1, 0.52, 0.68, and 0.76) were investigated in a broad temperature range from 77 to 300 K. The increase of Mn content in the Fe:Cd1-xMnxTe crystals was shown to result in an almost similar long-wavelength shift of absorption, fluorescence, and laser output spectra of about ~20 nm per each 10% of manganese. Laser generation was achieved in all crystals with the output energies up to 5.7 μJ. The central oscillation wavelength can be set by temperature as well as manganese content in the range 4950 up to 5650 nm.
