Abstract
In a general aspect, a chirped optical pulse is compressed by operation of diffraction gratings and a dispersive mirror having a smooth reflective surface. In some aspects, a chirped pulse laser system includes a programmable optical dispersive filter (PODF) operable to modify a spectral phase of optical pulses and a pulse compressor that receives an optical pulse based on an output of the PODF. The pulse compressor includes optical elements in a vacuum chamber. The optical elements define an optical path through the pulse compressor, and are arranged to disperse the optical pulse in the optical path. The optical elements include diffraction gratings and a dispersive mirror, which has a smooth reflective surface that defines a portion of the optical path.
