As well-known fact, the relation between the radius of TM00 mode of solid laser and 1/ft (the focal power of crystal) can be expressed with double U curves'1. In this paper, self-Q-switched of Nd:YVO4 solid laser of asymmetry flat-flat cavity was studied theoretically and experimentally, using this character. Self-Q-switched giant pulses with 200ns (FWHM) were observed in experiment. Pumped pulse width was 100µs. Peak power of laser pulse was several million times than the CW level. The experiment results were in good agreement with the theory. Giving the result of experiment, we offered a method to enhance the peak power of pulse.
