Laser projectors used for entertainment applications utilize laser modules to generate 4K-resolution images with a robust color palette and up to 75,000 lumens. While commercial laser projector systems quickly have evolved to be more energy-efficient, these systems still require up to 6kW to generate bright, high-resolution images. This is needed to project in cinemas and large venues at stadiums. Consequently, the high-power laser systems generate a significant amount of heat during operation. Heat can degrade the sensitive laser components, including the laser module (laser diodes and laser optics), optical scanning system, and laser diode driver electronics.
