In order to suppress the nonlinear effect caused by the interaction between laser and plasmas, precision physics experiments on inertial confinement fusion require a high power laser driver with the capability of fine adjusting in time-frequency domain. Based on technologies of polarization-maintaining fiber and single-polarization fiber, double oscillators with temperature tuning combined with two-class waveguide phase modulators are adopted to achieve the precise adjustment for laser pulse in frequency domain. Besides, the technology of two-class high speed electro-optic modulation pulse shaping is used to achieve laser pulse precision control in time domain. The sampling detection for microwave radio frequency signal is interlocked with the acoustic-optic switch to ensure the safe operation of the whole system. The continuous adjustable laser pulse in micro-joule level is experimentally obtained with bandwidth range of 0.15-0.3 nm, central wavelength range of 1052.4-1053.6 nm and wavelength tuning accuracy of 0.1 nm. The contrast ratio of shaping laser pulse is as far as 500∶1 in micro-joule level, and the modulation degree of pulse time waveform at top is lower than 10%.
