This article deals with lasers in the red spectral region, ie the red laser with awavelength roughly around 625-700 nm. The following type of red laser is the most common:
Red laser diodes, based on such GaInP or AlGaInP quantum wells, are availablewith different output, ranging from a few milliwatts (single emitters, VCSEL) in the order of 100 W diode bars. Typical wavelengths are 635, 650 and 6
