Lasers in High Energy Physics

We review the ubiquitous applications of lasers in high energy electron accelerators: as photo-injectors, for elegant diagnostics, and for the generation of high energy photons. We next discuss the search for low mass particles through the interaction of laser beams with transverse magnetic fields. We conclude with remarks about laser acceleration of electrons and protons and the status of the most intense available laser sources.
