Abstract
A display system for providing a user viewable visible color image includes a display for receiving color laser light so that the display, in response to color laser light, produces a viewable visible colored image; a plurality of different color laser light sources arranged in an array with each such laser light source including: a first dielectric stack for receiving and transmitting pump-beam light and being reflective to laser light over a predetermined range of wavelengths; an organic active region for receiving transmitted pump-beam light from the first dielectric stack; and a second dielectric stack for reflecting transmitted pump-beam light and laser light from the organic active region back into the organic active region. The display system projects color laser light from the array onto the display in a pattern to cause a visual image to be produced by the display.
