Pulse generation at 1.5-µm wavelength in new EAT14 glasses doped with Er³⁺ and Yb³⁺ ions

The paper describes investigation of pulse laser generation in newly developed EAT14 glasses with the use of MALO saturable absorber. Different initial transmission of the saturable absorbers and different transmission of the output coupler were investigated. The laser generation was carried out using 976-nm pump wavelength. Comparison of peak powers, slop efficiencies and thresholds was made with a view to choose the best set of glass and saturable absorber for "eye-safe" microchip laser range-finder. The generated wavelengths by each sample were measured.

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

The paper describes comparison of laser generation of concentrated and SELG glasses developed at the General Physics Institute of Russian Academy of Sciences in Moscow and most recent EAT14 glass worked out by the CLaser Photonics Company in Shanghai. The laser generation was carried out using 976-nm pump wavelength in cw and quasi-cw regimes. Comparison 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.
