Colorful spectral dispersion

Colorful spectral dispersion is observed through diffraction from a multilayer-dielectric grating. Several large-aperture diffraction gratings are used to compress the pulse width of the OMEGA EP short-pulse laser beams. LLE is investigating high-damage-threshold grating designs and manufacturing processes to increase the energy delivered to target.
