Laser rods (from left to right): Ruby, alexandrite, Er:YAG, Nd:YAG. A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. [1] Semiconductor-based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers, called ...
The weakest of all the q-switched devices and somewhat similar to the Ruby laser in that the Alexandrite creates a red light which is highly absorbed by green and dark tattoo pigments.

The Alexandrite effect has also been observed in some other minerals, such as fluorite, sapphire, kyanite, monazite, spinel, garnet, tourmaline, and rare-earth oxalates. Not to be confused with the alexandrite effect, some minerals also exhibit pleochroism. The former is a response to different wavelengths of light in general, the latter an ...
Cryogen spray: sprayed directly onto the skin immediately before and/or after the laser pulse; Air cooling: forced cold air at -34 °C; In essence, the important output parameter when treating hair (and other skin conditions) is power density – this is a combination of energy, spot diameter and pulse duration.
