Solid State Lasers
The excited medium of solid-state lasers consists of a glass or crystal doped with an ion, which will determine the wavelength produced. The pumping of glasses is done by flash lamp. Crystals can be pumped by flash or by another laser of suitable wavelength.
Capable of emitting from infrared to ultraviolet, solid-state lasers provide high power and can be operated in continuous or pulsed mode. Solid-state lasers can reach a wide range of wavelengths and are gradually replacing other technologies.
Solid state lasers are particularly robust and offer lifetimes in excess of 10,000 hours. For this reason, they are very popular for industrial applications: research, welding, marking, cutting, storage, etc.
