110 W All Fiber Actively Q-Switched Thulium-Doped Fiber Laser
IEEE Photonics Journal, 2015 We report a 100-W-level, repetition rate and pulsewidth tunable, all-fiber, thulium-doped master oscillator power amplifier system. The master oscillator was actively Q-switched by a fiber-coupled acousto-optic modulator.
