Mitsubishi Electric to Launch High-power 638nm Red Laser Diode for Projectors
Unprecedented 3.0W pulse-light output power will lead to extra-bright and miniaturized projectors
TOKYO, December 19, 2018– Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it will
launch the ML562G86 pulse laser diode (LD) for projectors, featuring a vibrant 638-nanometer (nm) red light,world-record output power of 3.0W under pulse operation and mean time to failure1 (MTTF) of over 20,000
hours, on April 1, 2019. The ML562G86’s high output power and wide operating temperature range willcontribute to enhanced projector luminance and miniaturization. Sample sales will begin on January 11, 2019.
1 Standard evaluation of reliability

High-power 638nm-wavelength red-laser diode (ML562G86)

Product Features1)

Unprecedented pulse-light output power of 3.0W and extended MTTF of over 20,000 hours- World's top output power of 3.0W, which is 20% greater than that of the company’s conventional model(ML562G84)- MTTF of over 20,000 hours thanks to improvements in LD chip structure and manufacturing processes- High output power and high-luminosity 638nm laser light achieve 145 lumens per LD2)

Wide operating temperature range will lead to projector miniaturization and cost reduction- Wide operating temperature range of 0 to 45 degrees Celsius at 3.0W pulse operation thanks to a large
9.0mm-diameter transistor-outline can (TO-CAN) package with excellent heat dissipation- World-leading 2.1W pulse-light output power at case temperature of 55 degrees Celsius- Wide operating temperature range allows simplified cooling structure, contributing to projector
miniaturization and reduced cost of cooling units

Projector light sources are shifting from mercury lamps to solid-state light sources that offer wall-plug
efficiency, a wide color gamut, and highly reliable operation. LDs achieve the best wall-plug efficiency amongsolid-state light sources, thereby contributing to lower power consumption, and thus are viewed as the mostpromising new light source for projectors. Mitsubishi Electric expects to use LDs to develop not only superior
projectors but also advanced laser TVs capable of more vibrant images than liquid-crystal TVs.
In September 2015, Mitsubishi Electric released its ML562G84 high-power red LD, which achieved 2.5W
output under pulse operation as a red LD in three RGB light sources for projectors. With conventional LDs,
extended operation at 3.0W output power causes the laser’s light-emitting surface crystals to melt, making it
difficult to achieve an MTTF of 20,000 hours. In response, Mitsubishi Electric has developed the technology
required to suppress degradation of the light-emitting surface even at 3.0W, leading to the newly announced
ML562G86 red LD that achieves unprecedented 3.0W output power.
