Learn More About Red Lasers

Red lasers typically emit light at around 650 nanometers. This wavelength corresponds to a specific range of energy levels in the laser medium, which can be achieved through various techniques such as gas discharge, solid-state, or diode pumping.

The output power can vary depending on the specific application, but they are generally low-power devices. Red lasers can be designed as continuous-wave or pulsed output and can be further modulated for specific use cases. They also often have a narrow spectral linewidth, which is useful for spectroscopy and other precision measurements.

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.
