Laser Wavelength Chart
Exciton, c. 1980
The origin of the laser was primed by the work of many, but Gordon Gould applied for a patent first in 1959, and the first demonstration of the laser would come the following year by Theodore Maiman. The following decades would see great growth and application, and a refinement of types. Here the "Exciton" company breaks down the five major groups and some of the specific wavelengths found in each.
