Findings

Idler pulse properties can be stably controlled by background intensity.

Analytical model predicts pulse duration and velocity tuning.

Potential for precise optical pulse manipulation.

Abstract

We predict that parametric sum-frequency generation of an ultra-short pulse may result from the mixing of an ultra-short optical pulse with a quasi-continuous wave control. We analytically show that the intensity, time duration and group velocity of the generated idler pulse may be controlled in a stable manner by adjusting the intensity level of the background pump.
