“…Similar methods with slight modification in geometry and growth parameters have been used [13][14][15][16][17] for bulk and QPM materials by several investigators. Some other modifications have been used for Fe-doped ZnSe for various applications [18][19][20][21], including mid-IR laser development.…”

The effect of sulfur, iron, and chromium doping on the electrical characteristics of ZnSe single crystals was studied. The crystals, grown by the physical vapor transport method (PVT) at NASA Marshall Space Flight Center, were characterized by measuring electrical resistivity, capacitance, and dielectric constant using LCR meter. The morphology was studied by scanning electron microscopy to determine the crystallinity and micro defects. The measured resistivity and dielectric constant showed tunability as the function of frequency in the range of 100 Hz to 100,000 Hz, indicating the suitability of doped material for tuning devices. Besides, for the range from 50 mV to 1000mV, there was no difference in values for the studied frequency range, indicating no degradation or breakdown in the material. All doped ZnSe crystals with sulfur, iron, and chromium showed a similar trend as the function of frequency. Cr-ZnSe showed very high resistivity and lower dielectric constant compared to S-ZnSe and Fe-ZnSe crystals.

“…The mid-IR lasers are highly transparent in the atmosphere and possess absorption peaks that overlap with many atoms and molecules, making them suitable for various applications such as spectroscopy, remote sensing, medical treatment, communication, industry, scientific research, etc. [1][2][3][4][5][6][7][8][9][10]. In certain situations, a mid-IR laser with a multi wavelengths will be needed, such as for remote sensing detection of different harmful gases, layered processing of multilayer organic matter, and so forth [11,12].…”

“…BGSe crystal is one of the most promising NLO crystal for mid-IR laser generation. It has a wide band gap (2.64 eV) and a wide transparency spectrum (0.47-18 μm) [8][9][10]. The BGSe has been extensively used in OPO operation in the mid-IR region, pumped by economical ~1 μm laser sources [14][15][16][17][18][19].…”

A multi-wavelength mid-IR laser consisting of 3.05 μm, 4.25 μm, and 5.47 μm BaGa4Se7(BGSe)optical parametric oscillators (OPOs) switched by DKDP electro-optic switches with one 10 Hz/7.6 ns pumping wave is demonstrated. Maximum energies at 3.05 μm, 4.25 μm, and 5.47 μm are 1.35 mJ, 1.03 mJ, and 0.56 mJ, respectively, corresponding to optical-to-optical conversion efficiencies of 9.4%, 7.6%, and 4.2%. To the best of our knowledge, this study is the first of generation of three mid-IR wavelength lasers using electro-optic switches. Furthermore, this study provides a viable solution for a high-energy or high-power, compact, or even portable multi-wavelength mid-IR laser device that employs a single pumping wave.

“…[4] Up to now, the HF lasers and xenon flash lamp pumped Er:YAG lasers have been the primary pumps for the high energy Fe:ZnSe lasers while the other pumps generated the Fe:ZnSe lasers with the output energy of several millijoules or less. [4] The HF lasers are usually employed as the pumps for short-pulseduration Fe:ZnSe lasers at room temperature, [5][6][7][8][9][10][11][12] and the Fe:ZnSe lasers and the pump both have the pulse durations of 100 ns-200 ns. For high energy Fe:ZnSe lasers with long pulse duration, the free-running 2.94-µm Er:YAG lasers at low temperature are the efficient pumps which have the pulse durations of several hundreds of microseconds.…”

We demonstrated an Fe:ZnSe laser pumped by a 2.93- μ m Cr, Er:YAG laser at liquid nitrogen and room temperature in single-shot free-running operation for the first time. The xenon flash lamp pumped Cr, Er:YAG laser had a maximum single pulse energy of 1.414 J, and the threshold and slope efficiency were 141.70 J and 0.70% which were respectively reduced by 29.3% and increased by 52.2% compared with the Er:YAG laser. At liquid nitrogen temperature of 77 K, the maximum single pulse energy of the Fe:ZnSe laser was 197.6 mJ, corresponding to a slope efficiency of 13.4%. The central wavelength and full width at half maximum (FWHM) linewidth were 4037.4 nm and 122.0 nm, respectively. At room temperature, the laser generated a maximum single pulse energy of 3.5 mJ at the central wavelength of 4509.6 nm with an FWHM linewidth of 171.5 nm.
