The technology of hot-pressed Cr2+:ZnSe ceramic preparation is reported. Comparative gain-switched lasing of hot-pressed ceramic and CVD grown Cr2+: ZnSe samples with slope efficiencies up to 10% and output energies up to 2 mJ were demonstrated. This is a milestone in the development of future large scale mid-IR laser systems based on ceramic TM2+:II-VI materials. This evolving technology has excellent potential as media for practical low cost, high power mid-IR laser applications. (c) 2006 Optical Society of America.

    ABSTRACT: Ceramic laser materials have come a long way since the first demonstration of lasing in 1964. Improvements in powder synthesis and ceramic sintering as well as novel ideas have led to notable achievements. These include the first Nd:YAG ceramic laser in 1995, breaking the 1 KW mark in 2002 and then the remarkable demonstration of more than 100 KW output power from a YAG ceramic laser system in 2009. Additional developments have included highly doped microchip lasers, ultrashort pulse lasers, novel materials such as sesquioxides, fluoride ceramic lasers, selenide ceramic lasers in the 2 to 3 mum region, composite ceramic lasers for better thermal management, and single crystal lasers derived from polycrystalline ceramics. This paper highlights some of these notable achievements.

    ABSTRACT: Recent progress in transition-metal doped II–VI semiconductor materials (mainly Cr2+:ZnSe and ZnS) make them the laser sources of choice when one needs a compact system with continuous tunability over 2–3.1 μm, output powers up to 2W, and high (up to 70%) conversion efficiency. The unique combination of technological (low-cost ceramic material) and spectroscopic characteristics (ultrabroadband gain bandwidth, high óproduct and high absorption coefficients) make these materials ideal candidates for “non-traditional” regimes of operation such as microchip and multi-line lasing. This chapter reviews these non-traditional Cr-doped mid-IR lasers as well as describes emerging Fe2+:ZnSe lasers having the potential to operate at room temperature over the spectral range extended to 3.7–5.1 μm. In addition to effective RT mid-IR lasing transition-metal doped II–VI media, being wide band semiconductors, hold the potential for direct electrical excitation. This work shows the initial steps toward achieving this goal by studying Cr2+ ion excitation into the upper laser state 5E via photoionization transitions as well as via direct electrical excitation. Keywords: Transition-metal doped II–VI; Cr2+:ZnSe; Fe2+:ZnSe; tunable mid-infrared lasers; photoluminescence; electroluminescence; photo-conductance.

    ABSTRACT: The microhardness of single-crystal samples of ZnSe: Cr2+ with a chromium concentration in the range from 3.3 × 1017 to 4.0 × 1019 cm−3 has been studied. The microhardness as a function of the load on the indenter on the faces (111), (1 $\bar 1$ 0), and (001) of the ZnSe: Cr2+ and ZnSe samples has been measured. It has been established that doping of zinc selenide with chromium leads to a decrease in the anisotropy of the mechanical properties and stabilization of the cubic sphalerite structure.
