Abstract

We present numerical simulations that indicate that backconversion in optical parametric oscillators depends strongly on the group-velocity mismatch (GVM) between the pump and the signal beams. Small GVM tends to suppress modulation of the signal, and the resultant narrow signal spectrum can favor strong backconversion. Large GVM permits a wider spectrum, which in turn can reduce backconversion. Comparison of simulation results and experimental data supports our theory.
