In our work we build a high repetition, high peak power and high average power laser which contains three main components: the fiber oscillator, the Nd:YAG regenerative amplifier, and the four-pass amplifier side-pumped by laser diode. The wavelength is 1064 nm. The laser operates at 100 Hz with pulse energies up to 112 mJ. And the average power is 11 W. The pulse width is tunable from 500 ps to 2 ns. The radius of the beam is 6.8 mm. The spatial profile of the beam presents nearly a top hat in the near filed and 1.5× diffraction-limited in the far filed.
