Abstract
An enlarged internal laser beam was used to project high-contrast images generated on a photochromic plate positioned within a laser cavity. An opaque image on the plate caused the coherent light passing through it to be diffracted. A flat, oblique apertured mirror reflected this diffracted light out of the cavity onto a screen.
