The Ultimate Guide to Red Light Therapy
3. How to Use
Your RLT Device
3.1 Difference Between
LEDs and Lasers
The history of RLT, also known as photobiomodulation (PBM), is closely tied to the
development of lasers.

Lasers, which stands for „light amplification by stimulated
emission of radiation,“ are special light sources that produce a focused beam of
light all at one wavelength (the distance between two consecutive peaks of a light
wave, which determines the color of the light). They were first invented in 1960 by
Theodore Maiman.
The use of lasers for healing began in the late 1960s when a Hungarian doctor named
Endre Mester discovered that red laser light could stimulate hair growth in mice and
help heal ulcers in humans.

This sparked interest in using red and near-infrared light
to treat various chronic diseases.
