“…Today, mid-infrared (mid-IR) lasers have already become a research hotspot in many related fields, [1] especially those whose wavelength lie in the so-called "atmospheric transport window" wavelength bands (3-5 μm, 8-12 μm), where lasers have further effective distance in the atmosphere. [2] Compared with other ways to obtain mid-infrared lasers, such as gas lasers, chemical lasers, semiconductor quantum well cascade lasers, and nonlinear frequency conversion device, [3][4][5][6] ion-doped solid-state lasers could directly output lasers from solid media, which is thought to be a simpler method. [7] To obtain mid-IR lasers, the active media of the solid-state lasers needs to be with low-phonon energy, because limited electron-phonon coupling and multi-phonon decay processes in these materials could significantly inhibit rapid DOI: 10.1002/crat.202200266 non-radiative decay between closely spaced laser ion energy levels due to lattice vibrations.…”

Transparent and homogeneous SrPb3Br8 single crystals with the size of Ø25 mm × 50 mm are grown by the modified vertical Bridgman method. X‐ray diffraction results reveal that the middle part of the crystal is pure in chemical compositions, while the tip part contains low content of Sr(PbBr3)2(H2O)5. X‐ray photoelectron spectroscopy analysis points out the absorption to C, O‐containing substances of the pristine surfaces of SrPb3Br8 wafers. The Raman results prove the low phonon energy of the SrPb3Br8 (116 cm−1). Transmission spectra demonstrate its wide transparent range (0.37–25 µm) and high transmittance in the mid‐infrared range except for several absorption lines. Moreover, Hall measurements show that the SrPb3Br8 sample is n‐type conductive at 110–300 K, and the Hall coefficient RH, resistivity ρ and mobility µH decrease as temperature increases while the carrier concentration n has an opposite trend. The conduction mechanism and scattering mechanism of SrPb3Br8 crystal at different temperatures has been studied by analyzing ln(|RH|)−T−1, n−T and µH−T curves, and the dominant donor defect ionization energy ED is calculated to be 0.077 eV.

An energy storage capacitor is crucial for both electrically pumped and optically pumped pulsed lasers. In electrically pumped lasers, the energy stored in the capacitors is directly deposited into the lasing medium, while in optically pumped lasers, it energizes the flash lamp that, in turn, pumps the lasing medium. We discuss here the application of energy storage capacitors in the operation of electrically pumped pulsed gas lasers. Increasing the operating pressure of the gain medium, a prerequisite for obtaining higher energy from the laser, has resulted in great advancements in the gas laser pulse technology. This progress has led to the development of transverse electric discharge pumping, enabling easy scalability of gas pressure and achievable output power. An ideal TE pulser efficiently charges the capacitor to an appropriate voltage with minimal energy dissipation on the charging element and facilitates a rapid and uniform transfer of this stored energy into the lasing medium before a glow-to-arc transition can set in. Various types of pulser circuits employed to energize pulsed gas lasers are described in this paper.
