Fine Frequency Tuning and ±3 MHz Frequency Stabilisation of a Nanosecond Mid-infrared Doubly Resonant Optical Parametric Oscillator

摘要

We demonstrate 100 GHz continuous tuning and ±3 MHz frequency stabilization of the signal radiation delivered by an entangled cavity nanosecond OPO while the frequency fluctuation of the pump radiation is larger than 500 MHz.
