Abstract
A method and system for compressing and amplifying light pulses using degenerate cross-phase modulation and degenerate four-wave mixing. A probe pulse and a pair of pump pulses are arranged so as to copropogate in condensed matter with the pump pulses having the same frequency as the probe pulse. The first pump pulse overlaps with the front end of the probe pulse while, the second pump pulse overlaps with the tail end of the probe pulse. The probe pulse is linearly polarized. The pump pulses are orthogonally polarized relative to the probe pulse so that they can be filtered out using a polarizer and have a greater intensity than the probe pulse. The propagation constant mismatch between the probe pulse and the pump pulses is equal to about zero.
