Abstract

Solid-state laser based on Er-doped gain medium, is a promising approach to designing directly diode-pumped eye-safer pulsed sources in the spectral range ~1.45-1.65 m. This approach allows obtaining spectrally broad laser outputs with high efficiency, if required by application (e.g., anti-speckle), without resorting to nonlinear conversions. All-fiber laser solutions for high PRF pulsed laser sources is deemed desirable, but it may result in high design complexity, especially on the Master Oscillator (MO) end, hence it is not appropriate in cases where low complexity is of major importance. Presented here are the results obtained with pulsed hybrid MOPA comprised of a bulk crystalline Er-based MO and Er-doped fiber amplifier.
