Abstract
An all-fiber polarization maintaining high-power laser system operating at 1.7 μm based on the Raman-induced soliton self-frequency shifting effect is demonstrated.The entirely fiberized system is built by erbium-doped oscillator and two-stage amplifiers with polarization maintaining commercial silica fibers and devices,which can provide robust and stable soliton generation.High-power soliton laser with the average power of 0.28 W,the repetition rate of 42.7 MHz,and pulse duration of 515 fs is generated directly from the main amplifier.Our experiment provides a feasible method for high-power all-fiber polarization maintaining femtosecond laser generation working at 1.7 μm.
