Compared to Light Emitting Diodes (LEDs) , semiconductor laser diodes have low power consumption, high-power output and can be used with optical systems having 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 638nm wavelength and 3.5W output(When pulse-driven) that provides highly visible, vibrant red colors for color projectors.
