CHIRPED-PULSE QUADRATIC NONLINEARITY-BASED HIGH-ENERGY PULSE COMPRESSOR

摘要

A pulse compression technique for compressing femtosecond-duration high-energy pulses first linearly chirps and thus broadens an input pulse before compressing it by nonlinear soliton compression. The technique simultaneously decreases the final compressed pulse duration and improves of the compressed pulse quality. In the preferred embodiment, a linear dispersive delay (12) is employed for chirping the pulse and a single quadratic nonlinear crystal (14) is employed for nonlinear soliton compression of the pulse.
