QUANTUM RADIATION IN ULTRA-INTENSE LASER PULSES...

Scientific advances and several technical breakthroughs have led to a remarkable increase in
available laser intensities over the past decades. In available ultra-intense laser fields 
photon fluxes may become so high that free charge carriers interact coherently with several of
the field's photons. In this thesis such nonlinear interactions are investigated for the prime
example of radiation emission by electrons scattered from intense laser pulses of arbitrary
temporal structure. To this end  nonlinear quantum field theory is employed taking the
interaction with the laser into account exactly. After an in-depth introduction to classical
particle dynamics as well as quantum field theory in nonlinearly intense laser fields the
emission of one and two photons is explicitly analyzed. The results are then translated to
viable technical applications  such as a scheme for the determination of the carrier-envelope
phase of ultra-intense laser pulses and a proposal for detecting the strongly suppressed
two-photon signal.
