“…However, there are experimental results demonstrating feasibility of the Cr:ZnSe lasing under electrical excitation via injected carrier recombination [41,90] as well as similar carrier processes (via photo-ionization transitions) induced by visible optical excitation [41,90]. Furthermore, as described in the next paragraph, the efficiency of energy transfer from the host to the lasing impurity is expected to increase in TM doped II-VI quantum confined structures.…”

“…Possibility of electrical pumping of mid-IR semiconductor lasers based on TM doped II-VI structures was investigated in several publications [34,41,[88][89][90]. This new type of laser could possess some advantages in comparison with other mid-IR laser sources such as quantum cascade lasers; semiconductor diodes (InAsSbP/InAsSb/InAs), and systems based on nonlinear frequency conversions (optical parametric oscillation and difference frequency generation).…”

Recent progress in chromium and iron doped II-VI semiconductor materials makes them the laser sources of choice when one needs a compact system with tunability over 1.9-5.1 μm. Output powers exceeding 10 W and efficiency up to 70% were demonstrated in several Cr doped semiconductors. The unique combination of technological (low-cost ceramic material) and spectroscopic characteristics makes these materials ideal candidates for mid-IR tunable laser systems. This article reviews transition metal doped II-VI materials and recent progress in Cr-and Fe-doped solid-state mid-IR lasers.Critical areas driving future progress in Cr-and Fe-doped chalcogenide middle infrared lasers: fabrication of binary and ternary II-VI ceramic gain media with low phonon cut-off, low optical losses and high design flexibility; high performance laser design with improved characteristics in power (power scaling to dozens of Watts), spectral (spectral coverage over 1.8-6 μm), temporal (frequency comb generation), and pump domains (electrically pumped Cr-and Fe-doped II-VI quantum confined structures).

“…Indeed, optically pumped RT lasers based on Cr:ZnS, Cr:ZnSe, Cr:Cd 1-x Mn x Te, Cr:CdSe, and Fe:ZnSe crystals providing access to the 2-3 and 3.8-5 µm spectral regions with high (up to 70%) efficiency, multi-Watt-level output powers, tunability in excess of 1000 nm, and narrow spectral linewidth (<20 MHz), have been reported by several groups (see e.g. reviews [2,3,4,5,6] and references therein). Arguably these lasers represent nowadays the simplest and the most cost-effective route for high power, broadly tunable lasing in the 2-3 and 3.8-5 µm wavelength ranges.…”

The white spaces correspond to elements of the matrix which are zero while the black spaces correspond to different nontrivial values which depend in a complex way on the parameters of all the interaction types.…”
