摘要:

A laser video projection method that is based on the image mode laser has been developed. The image mode laser is a laser with a spatial light modulator placed inside an optically pumped high-gain laser cavity to provide area-selectiveQ-modulation. The transverse mode of this laser creates a desired image that can be projected onto a viewing screen. This method of creating a lasing projected image has the potential advantages of higher contrast and brightness at the faceplate over the traditional method of spatial light modulation of a uniform optical source. The elimination of scanning systems results in a simpler design without mechanical parts; also, this system can potentially be adapted to full color with a single laser providing optical pumping for image mode lasers of all three primary colors.
