The first active laser was invented in 1960 by Theodore Maiman, with the first high-powered lasers (surgical lasers) able to cut through skin appearing in 1965.

In 1966, Hungarian Professor Endre Mester was researching the possible adverse side effects of low-lower (soft) lasers, and when he discovered that not only do soft lasers lack any adverse side effects but on the contrary boast a beneficial biostimulative effect on the human body, it was immediately concluded that the cells and tissues lit by soft laser light are able to heal and regenerate faster.

Since 1963, the development of laser has been one of the primary focus areas of research for Karoly Rozsa, Ph.D., a research physicist and doctor at the Hungarian Academy of Sciences. In the late 1970s, a Hungarian research team consisting of doctors and physicists realized that the polarization of laser light plays a significant role in the biostimulative effect yielded; since lasers at that time were very expensive, of low-efficiency and were dangerous to human eyesight, this research team created a much cheaper and safer ordinary lamp, the light of which they polarized. Indeed, this was the predecessor of today’s polarized lamps (i.e. Bioptron).

The success story of the next 30 years proved how beneficial polarized light is to the human body – however, it is believed that recently-developed semiconductor lasers are much more powerful, efficient and cost-effective than the polarized lights, though still posing a danger to the human eye.

In 2012, after several years of research, Dr. Rozsa created a special diffusion soft laser that remains harmless to the human eye, thus making it possible to replace the polarized lights for a much more effective therapeutic laser light that can be used in the comfort of your own home.
