Sub-nanosecond timing jitter in a passively Q-switched microlaser by active Q-switched laser bleaching

We report a diode-pumped, single frequency, low timing jitter passively Q-switched Nd:YAG/Cr4+:YAG microlaser. 245 μJ, sub-nanosecond pulses within 632 picosecond pulse-to-pulse timing jitter by optical bleaching using an actively Q-switched pulsed laser.
