Red Lasers

What are Red Lasers?

Image Red LaserRPMC is the largest red diode laser supplier in North America. See our wide range of Red Lasers for sale! We offer the widest range of wavelengths, powers, and package types for red laser diodes, and we offer a wide range of other red laser products. People often picture red laser pointers when they think of red lasers. However, there are many types of red lasers on the market. We do not offer laser pointers, but we do have red laser line modules (laser line generators) and many other types of lasers generating red wavelengths.

Red laser diodes, which are typically fabricated out of GaInP or AlGaInP, are the most popular and well-developed laser diodes available on the market today.  Red diode lasers are instrumental in a wide variety of applications ranging from inexpensive laser pointers to laboratory flow cytometry systems. 632.8 nm red light is the standard for helium-neon (HeNe) lasers, though they can produce green, yellow, and other wavelengths. HeNe lasers have been around for many years and are a tried-and-true staple in laboratories everywhere. Red HeNe lasers are often used for interferometry and laser alignment, for example. Wavelength shifted DPSS lasers can produce red wavelengths through the process of harmonic generation (frequency doubling in this case). Red wavelengths can also be generated through the use of optical parametric oscillator (OPO) technology.

Some of the most common red wavelengths are 635 nm, 650 nm, and 670 nm. On the shorter end of the red spectral region, the wavelengths are more visible to the human eye, but they aren’t as easy to efficiently generate.
