Patent Images
1. A system comprising:
- an optical amplifier configured to optically amplify a chirped optical pulse; and
an optical pulse compressor configured to compress the optically amplified chirped optical pulse, the optical pulse compressor includinga bulk optical grating configured to spatially disperse the optically amplified chirped optical pulse into a spatially dispersed optical pulse and direct the spatially dispersed optical pulse in a first direction along a first path, andan optical phase mask configured to perform dispersion compensation of the spatially dispersed optical pulse by adjusting an optical phase; and
an optical pulse stretcher coupled to the optical amplifier and configured to output a chirped optical pulse to the optical amplifier.

Abstract
A chirped pulse amplification (CPA) system comprises an optical pulse stretcher and an optical pulse compressor that are mismatched in that the optical pulse compressor includes a bulk optical grating while the optical pulse stretcher does not. High order dispersion compensation is provided by an optical phase mask disposed within the optical pulse compressor.
