Abstract: A system for generating pulses of charged particles, comprising a high intensity pulsed laser emitting laser pulses which, when impacting a target, generate pulses of charged particles. The particles passes through an electromagnet energized by a low inductance current feed incorporating a light activated switch to turn the energizing current on and off. Part of the light of the laser pulse is directed onto the light activated switch, such that the magnetic field is optically synchronized with the generated pulses of charged particles. This enables energizing the magnet only during passage of the pulses, such that it is lighter and more energy efficient than prior art systems using CW electromagnets. Synchronization also enables selection of charged particles having a predetermined range of particle energy, by timing activation of the magnetic field such that it diverts onto a selected beam path only the particles having the predetermined range of energies.

Abstract: A system and methods for the quasi-remote compression and focusing of a moderate-intensity laser pulse to form a much higher intensity beam that can be directed at a target and used as a probe beam or used in a probe beam converter to generate other forms of electromagnetic radiation or energetic particles. A system for the quasi-remote propagation of high-intensity laser beams in accordance with the present invention comprises a main platform on which a first, “seed” laser pulse is generated, stretched, and amplified, and a remote platform, located at a distance from the main platform, which is configured to receive the amplified and stretched pulse and convert it into the high-intensity laser beam. The high-intensity laser beam in turn can then be converted into one or more probe beams directed at a target object.
