The most common and technologically advanced laser diodes on the market at the moment are red lasers, which are commonly made of Ga In P or Al Ga In P. From cheap laser pointers to laboratory flow cytometry equipment, red diode lasers are essential in a wide range of applications.
Helium-neon (He Ne) lasers typically emit 632.8 nm red light, while they can also produce green, yellow, and other wavelengths. He Ne lasers are a tried-and-true standard in laboratories all around the world and have been around for many years.
For example, interferometry and laser alignment frequently use red He Ne lasers. Through the process of harmonic production, wavelength-shifted DPSS lasers can produce red wavelengths (frequency doubling in this case). Through the use of optical parametric oscillator (OPO) technology, red wavelengths can also be produced.
The most popular red wavelengths include those of 635 nm, 650 nm, and 670 nm. The wavelengths are more apparent to the human eye at the shorter end of the red spectral range, but they are more difficult to efficiently produce.
The Global red laser diodes market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 20244 to 2030.
Mitsubishi Electric Corporation will introduce the ML562G86 pulse laser diode (LD) for projectors, which boasts a brilliant 638-nanometer (nm) red light, a 3.0W output power under pulse operation that sets a world record, and a meantime to failure1 (MTTF) of more than 20,000 hours.
The high output power and wide operating temperature range of the ML562G86 will aid in the downsizing and improvement of projector brightness.
a large 9.0mm-diameter transistor-outline can (TO-CAN) package with outstanding heat dissipation, which enables a 3.0W pulse operation over a wide operating temperature range of 0 to 45 degrees Celsius. a world-leading 2.1W pulse-light output power at case temperature of 55 degrees Celsius.
Projector miniaturization and lower cooling unit costs are facilitated by the wide operating temperature range that simplifies cooling structures.
