is a Low Level Laser?
Strictly speaking, therefore, lasers are light amplifiers if the radiation produced is within the visible range, or radiation amplifiers if the radiation produced is within the infrared or the ultra-violet ranges.
The laser is a light source that generates extremely pure light. With pure light we mean light that has a single wavelength, not a whole spectrum. For illustration's sake imagine the following: the sound of a flute is purer than the sound of a can that has been filled with stones and is being shaken. The flute generates a sound with a specific tone (a certain wavelength). Just as in the case of the flute, the laser gives off waves that stay coherent for a long time. Light from laser is highly ordered, well organized, while the light from ordinary light bulbs is typically un-organized. Laser light is called coherent.
The "pure" sound of a flute can affect humans and matter in a way that is different from "un-pure" sounds such as traffic noise. The pure tone with the right frequency can cause a crystal glass to resonate, it may even shatter it. Similarly, coherent light can affect our tissue cells in the manner different from non-coherent light.
There are hundreds of different types of lasers. They can be manufactured as high power and low level lasers. Laser light can be of any color, or it can be invisible. The laser beam can be made small and parallel, or divergent.
light of the Low Level Lasers causes photochemical reactions in the cells.
Low Level Laser light photons are absorbed by antenna pigments (chromophores) within
the cells. This induces increased production of cellular energy (ATP)
which leads to normalization of cell function, pain relief and healing.
The effect of Low Level Laser Therapy (LLLT) is especially striking in
areas of the body where cells are under stress; it sometimes borders on
