The History of Laser and the Polarized Light in Medicine 

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, 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.

Endre Mester was born on November 20, 1903 in Budapest, Hungary. He studied medicine at University of Pécs, Hungary until 1927. He then taught surgery at the Pazmany Peter University in Budapest, while working with Dr. Lajos Adam. He was certified both in surgery and in radiology.

Theodore H. Maiman worked as a private consultant in high technology fields (1983-2007). Prior institutional affiliations included TRW Electronics Company and Laser Video Corporation. His research interests included condensed matter physics and lasers.


Laser light increases cell metabolism to the point that new cells, tissues and capillaries are formed, with soft laser light stimulating the immune system – put succinctly, laser light stimulates the body’s own healing ability. In addition to the above, soft laser light boasts a number of beneficial effects on the body, including inflammation and swelling reduction, pain killing, muscle tension reduction and hair growth acceleration. 

 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.
