We have demonstrated the generation of optional pulse shape by Yb doped fiber laser system. Yb fiber laser system operated the polarization-maintained pulsed at 1064 nm for single-transverse and -longitudinal mode using fiber Bragg grating (FBG), and this system generates optional pulse shapes that sliced up the Yb fiber oscillator by a LN (LiNbO3) intense modulator with 12.5-GHz bandwidth. The developed electronic-pulseshape generator supplies an arbitrary-voltage pulse to an integrated optic LN amplifier modulator which modulates the laser pulse. The output laser waveforms can obtain corresponding to the electronic waveforms such as rectangular, Gaussian and multi pulses with a 300-ps resolution.
