“…To date, significant progress has been made in studies of lasers based on chalcogenide crystals doped with transition metal ions [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Relatively recently, publications have appeared [3][4][5][6] devoted to a new laser based on a Fe:CdTe crystal.…”

“…Accordingly, the output energy of the secondstage Fe:ZnSe pump laser did not exceed 30 mJ. The pump energy of the Fe:CdTe laser can be significantly increased (up to at least 1.5 J) by using the Fe:ZnSe laser excited by a nonchain electric discharge HF laser [9,11]. However, the twostage pumping scheme is rather complicated in itself, which causes a number of inconveniences in experiments.…”

The operation at room temperature of a single-crystal Fe:CdTe laser excited by a nonchain electric-discharge DF laser was studied. The output energy of 29 mJ was obtained with a slope efficiency in terms of absorbed energy of 30%. The development of transverse parasitic oscillation at large pump spot sizes on the crystal surface limited the laser output energy. The laser with a nonselective cavity operated in the range of 5.3–5.9 μm; the total width of the generation spectrum was about 600 nm. Comparison of the Fe:CdTe generation spectra, obtained by pumping the crystal with DF and Fe:ZnSe lasers, confirmed the shift of the generation spectrum to the long wavelength region with increasing pump wavelengths. The maximum generation wavelength of the Fe:CdTe laser with a nonselective resonator excited by the Fe:ZnSe laser was 6.02 μm with a total width of the generation spectrum of about 370 nm. Ways are discussed for further increasing the room-temperature output energy of a Fe:CdTe laser.

“…In recent years, the main efforts of researchers have been directed both at improving existing and developing new technologies for producing Fe:ZnSe active media. The combination of chemical vapour deposition (CVD) method, hot isostatic pressing (HIP) and solid-state diffusing bonding (SSDB) technologies for obtaining active elements with internal doping layer(s) and large-diameter disk elements made it possible to overcome the limitations of the lasing characteristics caused by the development of parasitic oscillations [3]. Thanks to the application of these technologies, the highest values of * Author to whom any correspondence should be addressed.…”

A technique was presented for obtaining laser media based on polycrystalline zinc selenide doped with iron from spray pyrolysis deposited films in the solid-phase diffusion process. The effect of the ligature film composition and the high-temperature treatment conditions on the lasing characteristics of Fe:(In):ZnSe active elements was investigated. Lasing with an energy of 100 mJ at a differential absorbed energy efficiency of 42% was obtained on 20 mm disk Fe:ZnSe element pumped by a pulsed electric-discharge HF laser.

“…Chalcogenide laser materials doped with transition metals are sources of powerful coherent radiation in the spectral range of 3.5-5 μm and are of great interest for scientific research and practical applications. [1][2][3] The main areas in which zinc selenide optical elements are used include night vision devices, IR lasers, radiometers, IR pyrometers, etc. [4,5] A material similar to zinc selenide is zinc sulfide, also widely used in the listed devices and systems.…”

Using the method of graphical thermodynamics and information about T‐X projections of binary and quasi‐binary systems, 76 isothermal cross‐sections are constructed in the temperature range 300–2500 K for the Zn‐S‐Fe system and 75 isothermal cross‐sections in the temperature range 300–2700 K for the Zn‐S‐Cr system from complete melting of the system to the state when the liquid phase in the entire concentration triangle has ceased to exist. The monovariant equilibria of the Zn‐S‐Fe/Cr ternary systems are studied by high‐temperature annealing in silica ampoules followed by quenching. The synthesized samples are investigated using X‐ray diffraction analysis, which confirms the presence of phases participating in these equilibria and the correctness of the constructed cross‐sections. In the ternary systems under study, it is assumed that there are 18 nonvariant and 39 monovariant equilibria for the Zn‐S‐Fe system, 35 nonvariant and 45 monovariant equilibria for the Zn‐S‐Cr system. The information obtained can be used to improve the technology of IR lasers based on active elements ZnS:Cr and ZnS:Fe.
