Er:YGG planar waveguides grown by pulsed laser deposition for LIDAR applications

“…A crystalline host has potentially better power handling capabilities than glass equivalents and, due to the higher accessible gains, offer relatively short device lengths, which helps to raise the threshold for the onset of Stimulated Brillouin Scattering (SBS) that would degrade the spectral characteristics of the narrow-band seed. The PWA architecture has already been demonstrated in airborne campaign missions with Yb:YAG as the gain medium and proven that it is a viable candidate for such applications [1].…”

Active and passive Q-switching operation of 1 μm Yb:YSP laser with an optical chopper/AOM and MoWS2 nanosheets

“…All-solid-state lasers with short pulses in the 1 µm wavelength region possess various promising applications in material processing, optical communication, remote sensing, medical procedure, nonlinear optical frequency conversion, and so on [1][2][3][4][5]. Q-switching techniques are usually applied to compress pulse duration and to produce high peak power laser * Author to whom any correspondence should be addressed.…”
