In a general aspect, quantum electrodynamic (QED) interactions are generated using a parabolic transmission mirror. In some aspects, a system for generating a QED interaction includes an optical pulse generator and a vacuum chamber. The vacuum chamber includes a parabolic transmission mirror in an ultra-high vacuum region within the vacuum chamber. The parabolic transmission mirror is configured to produce the QED interaction in the ultra-high vacuum region based on an optical pulse from the optical pulse generator. The parabolic transmission mirror includes an optical inlet at a first end and an optical outlet at a second, opposite end. The parabolic transmission mirror also includes a parabolic reflective surface about an internal volume of the parabolic transmission mirror between the first and second ends. The parabolic reflective surface extends from the optical inlet to the optical outlet and defines a focal point outside the internal volume of the parabolic transmission mirror.

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.

A method for generating an ultrashort charged particle beam, comprising creating a high intensity longitudinal E-field by shaping and tightly focusing, in an on-axis geometry, a substantially radially polarized laser beam, and using the high intensity longitudinal E-field for interaction with a medium to accelerate charged particles.
