Dither-Free Stabilization of a Femtosecond Doubly-Resonant OPO using Parasitic Sum-Frequency Mixing

A new stabilization paradigm for degenerate femtosecond OPOs is demonstrated in a Ti:sapphire-pumped PPKTP OPO. Based on parasitic sum-frequency mixing, the approach achieves long-term locking and a tenfold reduction in relative-intensity noise compared with dither-locking.
