title: Phase-coherent generation of tunable visible femtosecond pulses.
abstract: Stable interference between the outputs of two noncollinearly phase-matched optical parametric amplifiers seeded by separate white-light continua has been observed. This means that the tunable visible pulses have a well-defined relative phase and that the temporal jitter between them is less than 1 fs. The residual phase variations are due to fluctuations of the pump power.
