Optical Phase Control of Ultrashort Femtosecond Pulse.

摘要

When optical pulses achieve durations as short as a few optical cycles, their propagation and nonlinear interaction properties will begin to depend on the phase of the optical waveform relative to its envelope. We have recently demonstrated the feasibility of controlling the relative optical phase of successive pulses from a laser and propose here to study the effect of that control on the pulse formation process itself as well as on other nonlinear optical processes. Phase stabilized Ti:sapphire and Cr:YAG lasers will be developed for experiments in two different wavelength regimes.
