Measurements of Raman gain coefficient for barium tungstate crystal

Abstract

Abstract:The Raman gain coefficient of a barium tungstate crystal was measured in the 532 nm to 1064 nm spectral region.

Characterization of Single-Crystal Synthetic Diamond for Multi-Watt Continuous-Wave Raman Lasers

“…The following sections describe measurements of Raman gain, absorption and Raman laser performance using these crystals. The Raman gain in the KGW and diamond crystals was measured using a standard pump-probe technique [30][31][32]. The experimental set-up is shown in Fig.…”

Effect of annealing on the structural and optical properties of laser ablated nanostructured barium tungstate thin films

“…Barium tungstate and strontium tungstate are prospective dielectric materials having both ferroelectric and piezoelectric properties and they have recently emerged as promising nonlinear materials for applications as Raman converters, Raman lasers and Raman amplifiers [12,13]. Barium tungstate is of particular interest as it shows more non-linear conversion efficiency compared to that of other tungstates [13]. There has been a recent high-lighted interest in scheelite structured BaWO 4 as a high quality material in electro optical manufacture.…”

“…Alkaline earth tungstates are key materials used for the instrumentation of low temperature particle physics experiments as scintillating particle detectors [10,11].

Eye-safe Nd :YVO4laser with intracavity SRS in a BaWO4crystal

“…The problem of development of such lasers is that the SRS gain decreases with increasing wavelength and, hence, it is necessary to use high pump powers, which may lead to optical breakdown of the crystal. The SRS gain at 1300 nm estimated by the data from [15] is 5.8 cm GW -1 .…”
