Abstract

Details of an image mode projection display are presented that utilize a twisted nematic display within the cavity of a laser. The reduction in the output efficiency of an image mode laser configuration due to amplified spontaneous emission is studied both theoretically and experimentally. It was found that in order to maximize efficiency, cavity loss should be minimized while maximizing the aspect ratio of the gain region and the optical pump rate.
