acronym of Light Amplification by Stimulated Emission of Radiation or light amplifier by induced emission of radiation. Source of light radiation with a very large number of identical photons (elementary particles of light), concentrated in a very small space. The laser beam that hits the tissues has the following effects:
Reflection – Transmission – Absorption – Diffusion.
The Laser-Fabric interaction depends on:
Wavelength – Power – Exposure time – Irradiated surface – Characteristic of the irradiated tissue.
The active medium of the laser generates different wavelengths, each of which affects certain molecules
The Diode Laser (810nm. 450nm.) Is attracted by Melanin and Hemoglobin, and has a penetrability in the tissues which varies from 4 to 6 mm. The Nd: Yag Laser (1064 nm.) Is extracted from the water molecule and penetrates the tissues for 12 mm.
Fundamental effects produced by laser energy on tissues are:
Photochemical effect: ATP increase
Photomechanical effect: accelerates the movement of the lymph
Photothermic effect: biochemical reactions
Vaporization of tissue
Less use of anesthetic
Accuracy of execution
Reduced and quality healing times
Recovery from Traumatic Processes
