Medical effect of 650nm laser

The functional principle of 650 nm laser irradiation. Laser is a major technology produced in the early 1960s and is regarded as one of the four great inventions of the 20th century (laser, semiconductor, atomic energy and computer). In the early 1990s, Russia first applied low-intensity laser to medical treatment, Russian astronauts took the laser energy introduction instrument into space as an important tool for adjuvant treatment and health care, which shocked the medical circles all over the world and called it "the light of life". The light wave with the wavelength of 650nm is called the "light of life" in the golden band of the human body by the world medical community. It can not only penetrate the skin, fat, muscle, blood vessel wall and other tissues of the human body, but also do not harm the tissues and cells of the human body. The emitted laser power is 5MW. It belongs to low-energy laser, and the irradiation density is far less than the damage threshold of body and blood damage. During nasal laser irradiation, the laser penetrates the human body without causing any damage to the body. A large amount of laser energy penetrates the blood vessel wall and other tissues and is absorbed by blood, which has a good therapeutic effect. It seems that Zhidun lipid-lowering semiconductor laser therapeutic instrument produced by Rhong LTD adopts this kind of laser therapeutic instrument.
