Introduction to the development history of laser

It has been nearly 30 years since laser cosmetology. It is widely used in the cosmetology industry. Do you know the development history of laser cosmetology, research on the biological mechanism of laser and introduction to laser cosmetology.

The research on the biological mechanism of laser and the development of laser medical equipment have advanced by leaps and bounds, which has led to the creative application of laser in clinical treatment and gradually penetrated into various fields of medicine.

Laser is short for amplification by the stimulated emission of radiation. The concept of laser can be traced back to the beginning of this century. In 1905, Einstein first put forward the light quantum hypothesis based on the general relativity theory, which started the discussion of the concept of laser. Then in 1917, Einstein put forward the stimulated radiation theory, which accelerated the maturity of the laser theory.

In 1960, in the laboratory of Hughes company in the United States, Maiman engineer manufactured the world’s first ruby laser. In the following decades, various applications of laser developed very rapidly, especially the most successful medical applications. Laser is a kind of high-energy beam, which can release energy in a short time, produce thermal effect on tissues, and cause selective damage; Laser is not radiation or radiation, and there is no doubt that it will cause mutation or cancer to cells.

Laser can cut, seal and evaporate skin tissue and blood vessels. The laser can produce a strong single wavelength beam, and its intensity and pulse time can be adjusted at will. The wavelength and power output of a specific laser determines its use in medicine.

For example, Q-switched laser can pass the millisecond, microsecond or even nanosecond super pulse time. The laser can instantly reach the deep layer of the skin through the epidermis of the skin, so that the pigment particles inside the skin are instantly crushed. The crushed pigment particles will be swallowed by human macrophages and transported away slowly.

Since the laser with a specific wavelength can reach the diseased pigment tissue through the epidermis and dermis, and only play a role in the pigment particles, the epidermis of the skin is rarely damaged or even not damaged, and there is no obvious damage to the texture of the skin. Therefore, no scar will be left on the skin. Different wavelengths of laser can selectively absorb the black, blue, green, brown, red, brown, yellow and other pigments in the skin.
