ABSTRACT:
This invention uses various solid-state semiconductor lasers along with frequency doublers as needed to achieve the required three-color light beam wavelengths for input to available light combiners and to a state-of-the-art scanner. The scanner projects a color laser beam to a screen or other equipment. A number of alternate solid-state laser means are described, each combination providing the required light output. Use of the described solid-state lasers instead of the commonly used gas lasers results in considerable savings in required electrical power, cooling and system size.
