The term "LASER" denotes Light Amplification by Stimulated Emission of Radiation. A laser is a device that generates an intense beam of light. Laser light has three special qualities that distinguish it from the conventional light source.
Ordinary light from a lamp consists of a mixture of wavelengths radiating in different directions and out of phase.
The argon ion laser emits a specific wave length (488–514 nm) of blue-green light found in the visible portion of the electromagnetic spectrum. About 80% of the energy is at wavelengths of 488–514 nm
The excitation medium is the ionised argon gas in a sealed laser tube, which is excited by a direct current electrical discharge.
The US Food and Drug Administration (FDA) has approved a range of argon laser machines for various skin disorders. These include The LASOS® Ar-Ion lasers (LASOS Lasertechnik, Germany), and Modulaser™ (Modulaser,Utah, USA). Individual machines are designed to treat specific skin problems.
The following skin disorders can be treated with argon laser beams.
