Abstract

A high-average-power OPCPA amplifier comprising a pump laser, a signal laser, and a nonlinear crystal amplifier. The pump laser includes an Nd:YVO4 laser oscillator-regenerative amplifier, an Nd:YAG boost amplifier, a frequency-doubling convertor, and a frequency-tripling convertor. The signal laser includes a supercontinuum generator, a pulse stretcher, and a pulse compressor. The chirped signal and the pump laser is intersected with a noncollinear angle of 3.0° to 4.0° in the nonlinear crystal amplifier and the temperature of the crystal amplifier is set at higher than 320K for simultaneous temperature- and wavelength-insensitive phase-matching.
