【Abstract】 Hybrid Q-switched Yb 3+ doped double clad fiber laser was studied using AOM and SBS of double clad fiber. Repetition rate of 1.5 kHz steady output pulses were achieved at the 1.24 W CW pumped power from tunable range of 1080~1119 nm. The pulse width was less than 6 ns and peak power was more than 13.3 kW. These parameters were firstly achieved in Q-switched fiber laser interiorly. The experimental results accorded with theoretical computation commendably.
