We report a hybrid DPSSL with a pulse parameter variable LD seed, all-fiberized polarizationmaintained pulsed Yb-doped fiber preamplifier chains, and a bulk Nd:YVO₄ power amplifier. Pulse parameter of LD seed was controlled by direct current modulation. The hybrid DPSSL generates 1064 ㎚ laser pulses with an average power of 40W, a pulse duration of 20-40㎱, and a repetition rate of 100-500㎑.
