Abstract

The disclosure relates to a light modulated electron beam-driven radiofrequency emitter. Pulses of light impinge on a photoemissive device which generates an electron beam having the pulse characteristics of the light. The electron beam is accelerated through a radiofrequency resonator which produces radiofrequency emission in accordance with the electron, hence, the light pulses.

Laser cavity optical system for stabilizing the beam from a phase locked multi-emitter broad emitter laser

Patent Scifres, D.R.; Sprague, R.A.

A laser cavity optical system is described for collimating a light output from a multi-emitter or broad emitter semiconductor laser capable of producing a multiple or broad low divergence output beam from the laser. The laser near field has a single beam waist position in a first spatial directional near the emission facet of the laser and having an elongated but phase coherent far field emitting pattern in a second spatial direction. A lens system is positioned at one facet of the laser for imaging the near field of the single beam waist position in the first spatial direction andmore »« less

Electron beam driven neutron generator

Patent Roberts, T.G.; Shatas, R.A.; Stettler, J.D.

An electron beam driven neutron generator is described. An electron source is connected to a beam forming and guiding section. A target is held by a portion of the beam forming and guiding section and has a magnetic field to control heat conduction by charged particles. Neutrons are produced at the target by interaction of the output from the electron beam source and the material forming the target.
