L-A-S-E-R is an acronym that stands for Light Amplification by Stimulated Emission or Radiation. Normal light consists of many wavelengths that scatter in different directions. A laser amplifies and focuses specific light frequencies into collimated beams of a single wavelength.
Although lasers can be found almost everywhere, from laser pointers in a classroom, to surgical lasers in operating rooms; therapeutic lasers are unique to the field of medicine. Therapeutic lasers are able to transmit energy below the skin level to the underlying tissue without harming the tissue it passes through. The light energy reacts in the body by creating physiological changes within the cells– a process called photobiomodulation. These benefits include pain reduction, decreased inflammation, increased blood circulation and improved healing time.
