Nail Fungus Laser Machine

Theory

A laser is a device which emits light in a very narrow band which is concentrated in such a way that it maintains temproal and spacial cohesion. In other words it makes a laser beam. Lasers are used for many things, and some of the first laser were used as knives. The lasers used in toenail fungus removal are not knives. They are more like the rays of the sun which can be life giving, but too much of certain wavelengths of light can be bad for human tissue. In this case scientist have determined that laser light in certain narrow ranges are deadly for some living tissue and not for others. It is one of these wavelengths that is deadly towards fungus found in toenails and not to other tissue found in toes.

Nd:YAG crystals are used in most laser toenail fungus removal treatments. They focus light into a wavelength of 1064 nm where according to many studies it has been found effective in treating toenail fungus. The laser can be continuous wave or pulsed from a Nd:YAG crystal so that the light energy is still damaging to toenail fungus but does not damage foot tissue, mainly through heat build up. Different laser treatments will also intermittently pulse to other lightwaves such as at 660 nm which is red visible light or 940 nm which is infared light.
