Abstract

We demonstrated >80 W picosecond output at a pulse repetition frequency of 100 MHz from a dual Nd:YVO4 amplifier laser system consisting of a phase-conjugate Nd:YVO4 bounce amplifier combined with a second diode-side-pumped Nd:YVO4 bounce amplifier. The output exhibited high quality spatial form with M 2 < 1.8 and a pulse duration (FWHM) of 9.2 ps. A peak power of >7.4 MW with an average power of 78.5 W was also achieved at a pulse repetition frequency of 1.0 MHz.
