Spontaneous generation of giant pulses was observed from a diode-pumped Nd:YVO4 laser with a plane-concave resonator by adjusting the cavity length near the hemispherical resonator configuration and misaligning the cavity axis with respect to the pump beam. Self-pulsation occurs because of the beating among near degenerate modes being tuned to resonate with the relaxation oscillation of laser modes. By using a concave mirror of 10-mm radius of curvature, giant pulses were obtained at approximately 10 kHz with pulse widths as short as 2.4 ns corresponding to an increase in the peak power of more than 4×104 times over the cw level.
