White-light generation has been used widely in single-shot f-to- 2 f interferometers for stabilizing the carrier-envelope (CE) phase of laser amplifiers. The accuracy of the relative phase values measured by such an interferometer is affected by fluctuations in the laser pulse energy. A simple two-step model is proposed to explain the mechanism that couples the laser energy and the CE phase. The model explains the experimentally observed dependence of the group delay between the f and the 2 f pulses on the laser energy, as well as the CE phase shift caused by the pulse energy variation.
