Multiphoton Intrapulse Interference. 1. Control of Multiphoton Processes in Condensed Phases

摘要: We explore and demonstrate the use of phase-modulated ultrafast laser pulses for controlling nonlinear optical processes in large molecules, proteins, solid materials. Our experiments illustrate that condensed phases, when spectra are broad, spectrum nth-order electric field, determined by multiphoton intrapulse interference, plays a major role excitation. These findings determine key parameters (amplitude, period, symmetry phase function) coherent femtosecond control phases.
