[PRJ2-4] High Power Red Laser Diode for Projector Light Source
Keywords:red laser, laser projector, speckle reduction, wall plug efficiency, tensile strain
We developed 638nm and 642nm red laser diodes with 3.5W pulse / 2.4W CW operation. The 3.5W pulsed operation and wall plug efficiency of 43% are the world’s highest in 638nm to the best of our knowledge. The lineups of multiple wavelengths are ideal as red light sources for projector.
