Abstract

A pulsed acousto-optic Q-switched all-fiber laser in master-oscillator power amplifier (MOPA) configuration is reported. The seed source is using LD as pump source, ytterbium-doped fiber as the gain medium, fiber Bragg grating (FBG) as resonator mirrors, acousto-optic Q-switch (AOM) as a modulator. The output of seed source is amplified by two stage amplifier. The second stage amplifier obtains the pulses of 10 W average power, 10-34 kHz repetition rate, 1064 nm center wavelength. When the repetition rate is 23 kHz, the pulse width is 275 ns and the 3 dB spectral width is 2.492 nm.
