Using fast switching high power diode laser driver, we are able to push the limit of accurate timing of the laser pulses from a passive Q-switched diode pumped Nd:YAG laser. Combined with prepumping technique, we could reduce the delay between pump current pulse and the laser pulse down to 2.5 micro-second, and the jitter of the delay down to 100 nanoseconds.
