We have developed a high‐efficiency optical system that uses multiple lasers as a light source. This optical system enables us to produce a novel laser projector with a high brightness and an ultra‐short throw distance. By utilizing the advantages of a laser, we have achieved a brightness of 7,000 lm and a throw ratio of 0.28 with an image size of 100–150 inches.
