This most obvious difference between green and red lasers [http://theunemployedmom.com/ The Unemployed Mom] is the wavelength of the beam. Green lasers have a wavelength between 560nm and 490nm with 532nm being the wavelength [http://theunemployedmom.com/ The Unemployed Mom] used for almost every laser. Some green lasers will have a wavelength of 526.5nm and green lasers can be made with other wavelengths such as 515nm, 523.5nm and 543nm. The wavelength [http://theunemployedmom.com/ The Unemployed Mom] for red lasers ranges from 700nm to 630nm with the most common wavelengths being 635nm, 655nm and 671nm.

The process used to create the laser beam in green lasers is very different [http://theunemployedmom.com/ The Unemployed Mom] from the process in red lasers. Red lasers are the simplest and the laser module (the section producing the beam) is just a diode and a lens. Green lasers on the other hand are much more complex and use a diode and a series of crystals and [http://theunemployedmom.com/ The Unemployed Mom] lens in a process called frequency doubling to produce a green beam.

In a red laser, the laser diode gives out [http://theunemployedmom.com/ The Unemployed Mom] red light. There are no commonly available diodes that give out green light so green lasers use a diode that gives out 808nm light. The 808nm is then [http://theunemployedmom.com/ The Unemployed Mom] converted to 1064nm by a crystal. The 1064nm light [http://theunemployedmom.com/ The Unemployed Mom] is then changed again, this time to 532nm.
