Abstract
We discuss the use of a class of exact finite energy solutions to the vacuum source-free Maxwell equations as models for multi- and single cycle laser pulses in classical interaction with relativistic charged point particles. These compact solutions are classified in terms of their chiral content and their influence on particular charge configurations in space. The results of such classical interactions motivate a phenomenological quantum description of a propagating laser pulse in a medium in terms of an effective quantum Hamiltonian.

Generating superpositions involving left and right qutrit states in H that cannot be reduced to decomposable states by a change of basis may offer a means to isolate and thereby control non-stationary entangled qutrits using appropriately fabricated meta-materials. In addition to such laser state “measurement” interactions with a classical medium, one may include interactions with atomic quantum states. These and other uses of such effective quantum Hamiltonians involving the dynamics of laser states will be discussed elsewhere
Summary
Advances in laser technology have made possible the exploration of physical processes on unprecedented temporal and spatial scales. They have opened up new possibilities for accelerating charged particles using laser-matter interactions. Multi- and single cycle high intensity (1010 − 1015 Wcm−2) laser pulses can be produced using Q-switching or mode-locking techniques [1]. Pulses of even higher intensity (∼ 1021 Wcm−2) could accelerate charged particles such as electrons to relativistic speeds where radiation reaction and quantum effects may influence their dynamics [2]. Lower intensity pulses have been used as diagnostic tools for exploring the structure of plasmas in various
