“…For the last 15 years considerable attention has been paid to investigations of optically pumped lasers on ZnSe:Fe 2+ [1][2][3][4][5][6][7][8][9][10][11][12]. This is explained by the need to obtain a powerful laser generation in the spectral range important for practical application λ = 4 ÷ 5 мкм.…”

Spectral and temporal characteristics of a ZnSe:Fe 2+ laser with a nonselective resonator pumped at room temperature by the radiation of a pulse-periodical electrodischarge HF(DF) laser are studied. It was established that the spectral distributions of the energy and peak power of ZnSe:Fe 2+ laser generation depend on a spectral composition of the pumping radiation. The spectra exhibit a line structure with spectral intervals between neighboring lines δ λ ≈ 6.8 ÷ 8.6 nm. The shape of the ZnSe:Fe 2+ laser generation pulse is wavelength dependent. In a short-wavelength range, the pulse has the form of a peak with a duration of ~5 ns at half-maximum. At a longer wavelength, the peak is accompanied by a 'tail'. The duration and amplitude of the tail increase with wavelength, in a long-wavelength spectrum range, the peak actually becomes unnoticeable on a background of the 'tail'. The spectral dependence of the ZnSe:Fe 2+ laser generation pulse's shape affects the positions of the energy and peak power maxima on the wavelength axis. The dynamics of ZnSe:Fe 2+ laser generation under the pumping by the pulsed HF(DF) laser is discussed.

“…As follows from this graph the maximum output pulse energy of ~ 200 μJ for incident pumping energy of 7 mJ was obtained for both active crystals at lowest 88 K temperature. Due to high losses in the laser cavity caused by CaF 2 windows and some active crystal misalignment the lasing in this scheme was obtained only for temperatures below 280 K, though room temperature operation of Cr,Fe:Zn 1-x Mg x Se (x=0.19) was previously reported 26 . For lowest 88 K temperature the oscillation wavelength was measured to be about 4600 nm, 4700 nm and 4800 nm for Mg content x of 0.19, 0.27 and 0.38, respectively which corresponds to local long wavelength fluorescence maxima in these crystals at low temperature.…”

The spectroscopic and laser properties of bulk Bridgman-grown Fe,Cr:Zn 1-x Mg x Se single crystals with the various concentrations of Mg (x=0.19; x=0.27; x=0.38) were investigated in the wide temperature range. The pumping was provided by a 2.94 μm Q-switched Er:YAG laser with a maximal energy of 15 mJ in 120 ns pulse, repetition rate 1 Hz. Q-switched operation was achieved by the Brewster angle cut LiNbO3 Pockels cell placed between the rear mirror and the Er:YAG laser active medium. The pump radiation was directed into the Fe:ZnMgSe crystal placed inside the LN cooled dewar. The 55 mm long plane-concave cavity was formed by a dichroic pumping mirror (T = 92 % @ 2.94 μm and R = 100 % @ 4 -5 μm) and a output coupler (R = 95 % @ 4.5 μm, r = 200 mm). The strong dependence of output pulse energy on temperature was observed for all samples. The maximum output Fe,Cr:Zn 1-x Mg x Se laser energy was 230 μJ and 180 μJ (for Mg concentration x=0.19 and x=0.38, respectively) for gain switched operation at 88 K. The central emission wavelength of ~ 4600 nm, ~ 4700 nm and ~ 4800 nm for Mg concentration x=0.19; x=0.27, and x=0.37, respectively at 88 K was obtained. The emission wavelength was found to increase up to ~ 4700 nm and ~ 4900 nm at 250 K for Mg concentration x=0.19 and x=0.38, respectively. This results show the possibility to obtain sufficiently longer oscillation wavelengths compared to previously studied Fe:ZnSe active medium especially at liquid nitrogen temperatures when pumping by free-running Er:YAG laser becomes possible. Fluorescence spectra and lifetimes of Fe 2+ ions in different Zn 1-x Mg x Se crystals in the range from 250 K down to 80 K were also measured.

“…Smaller values of the crystal field in Cd 1−x Mn x Te crystal results in smaller energy splitting of impurity ion in the lattice [8], which causes the shift of the emitted wavelength further into the mid infrared compared to ZnSe. From experiments with solid solutions of various compositions, for example ZnMgSe:Fe, it is possible to expect that various concentrations of manganese in Cd 1−x Mn x Te should influence the positions absorption and fluorescence spectra of Fe 2+ ions in such solid solutions [10].…”

Spectroscopic and laser properties of Fe 2+ -doped Cd 1−x Mn x Te solid solutions in a wide range of Mn concentration (x = 0.1-0.78) are investigated under excitation by a cryogenically cooled ZnSe:Fe 2+ laser (λ = 4080 nm) and by a PbGa 2 S 4 :Dy 3+ laser (λ = 4335 nm). To our best knowledge, lasing of Fe 2+ ions in CdMnTe crystals is demonstrated for the first time. The laser worked in a nonselective cavity at 77 K within the 4950-5270 nm spectral range depending on the Mn concentration x.
