When adopting mode-locked Nd:YAG laser to choose single pulse, KD*P Pockels cell is usually used. The half wavelength voltage is 6.6 kV to the laser of 1.06μm wavelength. In recent years, cold cathode thyratron KN-22 is widely used in circuit, but here KN-22 is replaced by MOSFET. The circuit with MOSFET has stable and credible performance, it can output a pulse of -6.6~-8kV and the pulse width can be adjusted from 5ns to 10ns. The circuit has a short time jitter (0.5ns), a delay of 30ns and high probability of selecting single pulse (100%). No abnormity is found after using a long time and the circuit can be also used as chopper and pulse shearer.
