Wang Lixin; Cai Jun; Jiang Peipei; Shen Yonghang

Based on the rate equations, a numerical model of double clad Q-switched fiber laser was built, and the all fiberized high power linear polarized pulsed ytterbium-doped fiber laser was developed by using a fiberized acousto-optic Q-switched fiber laser as the seed source, a double clad ytterbium-doped fiber as the gain medium. In the pump power of 38.4 W, repetition rate of 40 kHz, pulse duration time of 30 ns, the laser delivered a linearly polarized pulsed emission output with an average power of 29.8 W. Its polarization extinction ratio was greater than 10 dB, and the beam quality factor (M2) was 1.32.
