“…In this experiment tunability between 2.1-2.85 µm was achieved at up to 10 W output power by use of an intracavity acousto-optical filter and the beam quality was characterized by M 2 = 1.85. Cr:ZnSe lasers are thus very interesting as affordable, compact, room-temperature operational and broadly tunable mid-IR laser sources for use in a variety of remote sensing applications [41,42]. Cr:ZnSe can also be used for mid-IR OPO pumping such as ZGP-or CdSe-based OPOs [43,44].…”

“…High average power tunable solid-state lasers in the wavelength range from 2 to 3 μm are attractive light sources for many applications, such as medical surgery and lasertripsy, laser processing, environmental remote sensing, wireless energy transmission technology, pumping mid-infrared optical parametric oscillators and solid-state lasers based on Fe 2+ -doped crystals [1][2][3][4][5][6][7]. Cr 2+ -doped zinc selenide (Cr 2+ :ZnSe) crystals are among the most attractive active media for high-average power lasers in the 2-3 μm wavelength range due to their wide tunability, broad absorption bands, and large stimulated-emission cross section [8][9][10][11][12][13].…”

High average power narrow-linewidth tunable solid-state lasers in the wavelength region between 2 to 3 μm are attractive light sources for many applications. This paper reports a narrow-linewidth widely-tunable laser system based on the polycrystalline Cr2+:ZnSe elements pumped by the repetitively-pulsed 2.1 µm Ho3+:YAG laser operating at the tens of kilohertz pulse rate. An advanced procedure of ZnSe-element doping and surface improvement was applied to increase the laser-induced damage threshold, which resulted in an increase of the output power of the Cr2+:ZnSe laser system. The high-average-power laser system comprised double master-oscillators and power amplifiers: Ho3+:YAG and Cr2+:ZnSe laser oscillators, and Ho3+:YAG and Cr2+:ZnSe power amplifiers. The output wavelength was widely tuned within 2.3-2.7 µm by an acousto-optical tunable filter inside the Cr2+:ZnSe master oscillator cavity. The narrow-linewidth operation at the pulse repetition rate of 20-40 kHz in a high-quality beam with the average output power up to 9.7 W was demonstrated.

We review a novel class of femtosecond Cr 2+ -doped ZnSe and ZnS lasers, which operates in a very important for applications wavelength range between 2 and 3.5 μm and which generates ultrashort optical pulses that are only five optical cycles in duration. Room-temperature Cr 2+ -lasers provide tens of Watts average power, >70% slope efficiency, ultrabroad tunability (∼1400 nm between 2 and 3.4 μm) in the continuous wave regime and GW-level peak powers in the amplified femtosecond regime. Different mode-locking techniques from Kerr-lens to graphene saturable absorbers have been demonstrated, and dispersion compensation methods from bulk materials to chirped mirrors allowed the realization of self-starting few-optical cycle oscillators and the demonstration of a number of applications in spectroscopy and nonlinear optics. The Watt level few-optical cycle Cr:ZnS oscillator 1 operating at 2.4 μm is distinguished by extremely short pulse duration of only 41 fs, hundreds of kilowatt peak powers, and tens of nanojoule pulse energies. Using the direct diode-pumping or fiber laser pump sources such a laser can be made reliable and compact, which paves the way to industrial realisation and applications in environmental analysis, oil and gas sensing, hazardous gas detection, breath analysis, fine material processing of semiconductors, composite materials, and glasses.
