Comparison of cw laser generation in Er3+, Yb3+: glass microchip lasers with different types of glasses

摘要

The paper describes comparison of laser generation of concentrated and SELG glasses developed at the General Physics In-stitute of Russian Academy of Sciences in Moscow and most recent EAT14 glass worked out by the CLaser Photonics Com-pany in Shanghai. The laser generation was carried out using 976-nm pump wavelength in cw and quasi-cw regimes. Com-parison of efficiencies and thresholds as well as of dissipative losses was made with a view to choose the best glass for “eye-safe” microchip laser range-finder. The generated wavelengths by each sample were measured.
