2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC).
For several last years there is a strong demand on a development of laser systems based on transition metal ions operating in the mid-infrared spectral range of 4 – 5 μm. We present a laser system based on the Cr 2+ ,Fe 2+ :Zn 1-x Mn x Se (x ≈ 0

2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC).
Due to the wide use of coherent radiation in the mid-infrared (IR) region, the attention has been paid to both direct and indirect methods of generation of this radiation over the past two decades. While indirect methods are based on nonlinear conver
