Laser is actually "light"
A laser is a device that emits light. The word ‘laser’ is actually an acronym. It stands for Light Amplification by the Stimulated Emission of Radiation. Lasers differ from other sources of light because they emit light coherently. This allows them to be ‘directed’ or focused on a particular area of the body.
WHAT IS "LOW LEVEL" LASER?
Soft laser, or low level laser, uses low intensity, coherent light in wavelengths typically up to about 1000nM. The light particles, known as photons, penetrate deeply into the tissue without heating or hurting the skin. The wavelength at which the laser emits determines the effective depth of penetration, within the tissue, of the laser energy delivered.
TIMELINE OF LOW-LEVEL LASER
While the history of photomedicine stretches back thousands of years, it was during the 20th century that the scientific application of particular wavelengths of light began.
