Abstract

We have shown by measuring the beat frequency between the supercontinuum (SC) and the optical parametric oscillator (OPO) 2ω _s subharmonic, we can observe and control the relative phase slip between the pump and signal. The relative phase slip can be controlled for a large OPO signal range since the 2ω_s subharmonic is mixed with the SC. It is possible to use the SC to extend carrier-envelope locking so that both the Ti:sapphire pulse and OPO signal are locked to an absolute reference
