Laser Diodes for Projectors

Compared to LEDs, semiconductor lasers have lower power consumption, higher output, and can be used with optical systems that have a higher maximum aperture. These considerable advantages mean that they can be used for projectors that do not require focal adjustment.
Mitsubishi Electric has a range of lasers available, including a multi-mode semiconductor laser with a wavelength below 640nm and 1W output (when pulse-driven), or 1.55W output (when CW-driven), that provides highly visible, vibrant red colors for color projectors.
