Paper Abstract

A high efficiency, narrow spectral linewidth lasing pixel device that implements a low-voltage spatially patterned variable loss element placed inside an optically pumped high-gain laser cavity is experimentally studied. The output properties of this system make it potentially useful for digital projection displays. Coupling and grey-scale control of an intracavity pixelated laser projected system is studied experimentally and by numerical simulation. Results indicate that pixel independence can be maintained in high Fresnel number resonators.
