摘要：

Active stabilization loops were implimented in a non-collinear optical parametric amplifier (NOPA) to reduce output pulse energy fluctuation. Proportional-integral-derivative feedback stabilizations of pump and seed energy reduced fluctuation of each controlled parameters more than 80% and resulted in more than 60% reduction of the final NOPA output energy fluctuation. This simple stabilization scheme is expected not to affect the capability of NOPA to generate ultrashort pulses, and hence this scheme can be applied to improve signal-to-noise ratio of the data obtained in experiments using NOPA.
