Abstract

As one of the core parts of a radar system,high-power kHz laser is extremely important in the study of atmospheric science.It is one of the feasible ways to achieve high-power kHz laser master oscillator power amplifier.In order to get the narrow pulse width,high beam quality kHz master oscillator laser,a diode end-pumped kHz electro-optic Q-switched Nd:YAG laser was used in experiments.A laser at 1064nm was obtained with repetition rate of 1kHz,pulse width of 5ns,pulse energy of 2.7mJ,optical-optical efficiency of 40%,M2=1.2.The results show that this laser provides a qualified seed source for 1kHz,500W,10ns green master oscillator power amplifiers.
