A Brief Introduction to Laser

The word laser is an acronym for Light Amplification by Stimulated Emission of Radiation.

Laser is an absolutely outstanding inventions of the last century. It has become a valuable tool in various fields, including medicine. Laser is a light source, but different from the traditional light source, it is not used for illumination purposes.

Laser light is the result of a process called stimulated emission. Stimulated emission occurs when an incoming photon stimulates an excited atom so that it emits a photon identical to the incoming photon. The incoming photon has to have a wavelength (i.e. energy) which is identical to the energy which the atom will release when it falls from the excited level to a more stable one.

The use of laser in medicine is clearly evident. I have used laser for the purpose of surgical and non-surgical procedures, mostly in otorhinolaryngology head & neck surgeries. The results were significant, i.e. minimal bleeding in minimal invasive surgery.

From what I have experienced, I concluded that laser is the therapeutic modality which is beneficial in numerous medical conditions. Surely, it promotes better quality of life and affect humankind, especially through biostimulation and anti-inflammatory effects of low power laser.
