Optical pulse compression
(AIP Publishing, 1974-11-15)
Dramatic and controllable reshaping of frequency-modulated dye laser pulses has been observed. The pulses, nearly resonant with the 2P1/2 line (7948 A) of Rb, first passed through a LiNbO3 frequency modulator, and then ...
Coherent excitation, incoherent excitation, and adiabatic states
(American Physical Society, 1976-08)
Coherent excitation of an atomic excited state occurs during the propagation of near-resonant light pulses and is responsible for the induced polarization. Simultaneously, incoherent excitation occurs due to the relaxation ...
Observation of self-steepening of optical pulses with possible shock formation
(American Physical Society, 1973-08-13)
Near-resonant light pulses were steepened by passage through Rb vapor. The rise time changed from typically 4 nsec to less than 1 nsec, and complicated envelopes developed. The self-steepening, well described by adiabatic ...
