Recent developments show that each wavelength has advantages but 650nm to 900nm is the best wavelength because it has the best combination of depth of penetration (low absorption), cellular interaction and energy transfer efficiency. There is a lot of literature emphasizing the optical window and how it is used to predict the best wavelength for therapy lasers. ![]() This is the optical window and it ranges from 650nm to 900nm and you can also see that the high-end extends up to about 940nm. In this graph, we can see a low valley in the center of the range where the light can travel the greatest distance. This graph shows the absorption of light into different component of the human body. ![]() Variations of this graph are used across the web. The following graph is republished from the book Laser Field Therapy by Anja Fuchtenbush, Volmar Kriesel and Peter Rosen. Near the end of this article we will analyze the overall therapy laser market to see some trends from the 25+ cold laser manufacturers and make some summary conclusions. Each of the wavelengths used in therapy lasers interacts with tissue in a unique way. The purpose of this article is to introduce laser newbies to the concepts of wavelength as an important operating parameter in cold lasers, PBM and laser therapy. ![]() The Most Options, Friendliest Service and Best Prices
