“…In our previous papers, we have developed an approach for creating a high-power femtosecond laser system based on the CPA of a mid-IR seed in an optically pumped Fe:ZnSe gain medium [66]. The amplification of nanosecond and femtosecond pulses in Fe:ZnSe was investigated in [67,68], correspondingly with further enhancements in energy extraction from the amplifier, up to 1.2 mJ [69].…”

This review highlights the development of ultrafast sources in the near- and middle-IR range, developed in the laboratory of Nonlinear Optics and Superstrong Laser Fields at Lomonosov Moscow State University. The design of laser systems is based on a powerful ultrafast Cr:Forsterite system as a front-end and the subsequent nonlinear conversion of radiation into the mid-IR, THz, and UV spectral range. Various schemes of optical parametric amplifiers based on oxide and non-oxide crystals pumped with Cr:Forsterite laser can receive pulses in the range of 4–6 µm with gigawatt peak power. Alternative sources of mid-IR ultrashort laser pulses at a relatively high (MHz) repetition rate are also proposed as difference frequency generators and as a femtosecond mode-locked oscillator based on an Fe:ZnSe crystal. Iron ion-doped chalcogenides (Fe:ZnSe and Fe:CdSe) are shown to be effective gain media for broadband high-peak power mid-IR pulses in this spectral range. The developed sources pave the way for advanced research in strong-field science.

“…To assess the potential for broadband amplification of ultrashort laser pulses, we modeled the multi-pass amplification using the Frantz-Nodvik approach [35] as we did in our previous research [22][23][24]. In the calculations we used the following input parameters: E in is the energy of the seed pulse; D is the waist beam diameter of the seed pulse inside the crystal; R represents non-resonant losses per pass in the amplifier (losses per pass in the amplifier minus the absorption losses in the crystal); L is the length of the gain medium; g 0 is the effective gain of the weak signal, taking into account radiation absorption losses in the active medium.…”

“…To confirm this, a laser system based on the regenerative amplification in Cr 2+ :ZnSe was recently developed, and produces femtosecond 0.3 mJ pulses near the wavelength of 2.5 µm [21]. Additionally, the concept of solid-state femtosecond laser systems with multigigawatt power levels in the range of 4-5 µm, and containing a two-stage amplifier based on the Fe 2+ :ZnSe crystal, was proposed in [22][23][24]. The first stage of its performance was realized in [25].…”

We report on the successful growth of single crystals of Fe 2+ :CdSe by seeded physical vapor transport (SPVT) technique with doping within the growing process and subsequent annealing in Se vapor. Luminescence lifetime measurements, spectroscopic studies of 5 E-5 T 2 transition of Fe 2+ in CdSe, and laser experiments were performed. The lifetime of the 5 T 2 energy level was measured to be 20 ± 5 ns at a room temperature (RT) of 290 K. At liquid nitrogen (LN) temperature, luminescence kinetics displayed a non-exponential decay, which can be fitted to a bi-exponential function with time constants τ 1 = 6 µs and τ 2 = 29 µs. As much as 3.2 mJ of output energy at 5.2 µm with 27% absorbed pump energy slope efficiency of an Fe 2+ :CdSe laser was achieved at RT under 2.94 µm nanosecond Er:YAG laser pumping. The Fe 2+ :CdSe laser was tuned from 4.63 to 6.10 µm. Obtained characteristics of Fe 2+ :CdSe indicate that the crystal can be considered a promising medium for amplification of femtosecond pulses in the middle infrared range up to 6 µm.
