Abstract
The timing jitter of passively Q-switched Nd:Y3Al5O12/Cr4+:Y3Al5O12 (Nd:YAG/Cr4+:YAG) laser is studied both numerically and experimentally. It is found that spontaneous noise in the microwatt range can significantly affect the repetition rate of high-power Q-switched lasers, and creates large pulse-to-pulse timing jitter. External modulation on the Cr4+:YAG saturable absorber by a laser diode is proposed to alleviate this jitter problem. Reduction in timing jitter by a factor of 2.5 is demonstrated.
