Abstract

A method and apparatus for increasing the coherence and reducing the emittance of a beam-shaped pulse operates by splitting the pulse into multiple sub-beams, delaying the propagation of the various sub-beams by varying amounts, and then recombining the sub-beams by means of a rotating optical element to form a pulse of longer duration with improved transverse coherence.

Apparatus and method for improving radiation coherence and reducing beam emittance

Patent Application Csonka, P.L.

This invention is comprised of a method and apparatus for increasing the coherence and reducing the emittance of a beam-shaped pulse which operates by splitting the pulse into multiple sub-beams, delaying the propagation of the various sub-beams by varying amounts, and then recombining the sub-beams by means of a rotating optical element to form a pulse of longer duration with improved transverse coherence. 16 figs.

Apparatus and method for improving radiation coherence and reducing beam emittance

Technical Report Csonka, P.L.

A partially coherent beam-shaped pulse of particles (referred to in the following as x-rays) is sectioned longitudinally into numerous beam-shaped pulses of smaller cross section. The diameter of these smaller beams more closely approaches the transverse coherence length desired in a particular experiment. The various beams are guided along separate paths which have different lengths in order to delay each pulse by a different period of time. The delayed pulses are then directed toward a rotating mirror which deflects them all along the same path, one after another. In this manner, a relatively wide and short beam-shaped pulse with poormore »« less
Method and apparatus for reducing coherence of high-power laser beams

Patent Moncur, Norman K. (Ann Arbor, MI); Mayer, Frederick J. (Ann Arbor, MI)

Method and apparatus for reducing the coherence and for smoothing the power density profile of a collimated high-power laser beam in which the beam is focused at a point on the surface of a target fabricated of material having a low atomic number. The initial portion of the focused beam heats the material to form a hot reflective plasma at the material surface. The remaining, major portion of the focused beam is reflected by the plasma and recollected to form a collimated beam having reduced beam coherence.

Apparatus and method for compensating for electron beam emittance in synchronizing light sources

Patent Neil, George R. (Williamsburg, VA)

A focused optical beam is used to change the path length of the core electrons in electron light sources thereby boosting their efficiency of conversion of electron beam energy to light. Both coherent light in the free electron laser and incoherent light in the synchrotron is boosted by this technique. By changing the path length of the core electrons by the proper amount, the core electrons are caused to stay in phase with the electrons in the outer distribution of the electron beam. This increases the fraction of the electron beam energy that is converted to light thereby improving themore »« less
