Alexandrite

What is an alexandrite laser?

An alexandrite laser is one that uses an alexandrite crystal is used as the laser source or medium. The alexandrite laser produces a specific wavelength of light in the infrared spectrum (755 nm). It is considered a red light laser.

How does an alexandrite laser work?

The wavelength of high energy light emitted by the laser is converted to heat energy and this damages the specific target area. Thus alexandrite lasers work by a process of photothermolysis: this means using light (photo) to heat (thermo) a selected area for destruction (lysis).

Alexandrite lasers cause very precise tissue destruction of the lesion and leave tissue in the surrounding area undamaged.

What is an alexandrite laser used for?

The US Food and Drug Administration (FDA) has approved a range of alexandrite laser machines emitting infrared light (wavelength 755 nm) for various skin disorders. The following skin disorders can be treated with Alexandrite laser beams.
