We report measurements of the thermo-mechanical properties of two recently developed non-chalcopyrite, trigonal, mid-IR nonlinear optical crystals, BaGa2GeS6 and BaGa2GeSe6. These include orientation dependent hardness and Young’s modulus, thermal

Nonlinear optical properties of a selection of gallium nitride samples have been measured using picosecond and nanosecond duration laser pulses at 532 nm. The values of the two-photon absorption coefficient, free carrier absorption cross section, and

We report a seeded optical parametric generator (OPG) producing tunable radiation from 4.2–4.6 µm. The seeded OPG employs a 13 mm long C d S i P 2 (CSP) crystal cut for non-critical phase-matching, pumped by a nanosecond-pulsed, MHz repetition rat

Temperature- and wavelength-dependent values of the ordinary (no) and extra-ordinary refractive index (ne) of GaN and 4H-SiC were measured over wavelength ranges of 1.9 to 7 μm and 1.9 – 5.5 μm, respectively, and over a temperature range of 79 to

We report a CdSiP2 (CSP) based seeded optical parametric generator (OPG), emitting sub-nanosecond duration, 3 MHz repetition rate, wavelength tunable mid-infrared (MIR) light at 4.2-4.6 μm. We generate up to 0.25 W at 4.2 μm with a total pump conve
