Create a laser from sun light Ask Question

Lasing media[edit]

The two most studied lasing media for solar-pumped lasers have been iodine,^[1] with a laser wavelength of 1.31 micrometers, and NdCrYAG, which lases at 1.06 micrometers wavelength. Solar-pumped semiconductor lasers have also been proposed by Landis^[2] and others.^[3]

Applications[edit]

Solar-pumped lasers are not used commercially because the low cost of electricity in most locations means that other more efficient types of lasers that run on electrical power can be more economically used. Solar pumped lasers might become useful in off-grid locations.
