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. 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, N.K.; Mayer, F.J.

The invention discloses a 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.
