Spectroscopic applications of programmable subpicosecond resolution laser pulse shaping

A method has been developed for producing voltage-programmable, arbitrarily shaped laser pulses with approximately 100-fs resolution and >107-W peak power. Rectangular 600-1500-fs pulses have been used to probe hot carrier relaxation by photoconductive sampling, and phase- and amplitude-modulated laser pulses have been used to create complex solitons in optical fibers. Other applications that illustrate the use of shaped laser pulses in atomic and molecular spectroscopy are briefly described, as is the use of optical analogs of spin-locking experiments to turn off intramolecular vibrational redistribution.
