YAG Laser Performance Interpretation and Main Uses
Because YAG crystal has the advantages of good optical homogeneity, good mechanical properties, high material stability, and good thermal conductivity, it is still the material of choice for solid-state lasers, and therefore it is widely used in the fields of industry, medical treatment, scientific research, communications, and military. Such as laser weapons, laser ranging, laser target indication, laser detection, laser marking, laser processing (including cutting, drilling, welding, and engraving, etc.), laser medical, laser beauty and so on.
Laser is a new type of light source that appeared in the early 1960s. Lasers have attracted widespread attention due to their high brightness, high monochromaticity, high directionality, and high coherence. They have rapidly become industrial and agricultural production, science and technology, and medical care. National defense and other fields have been widely used. Laser medicine is the product of the organic combination of laser technology and medical science. Lasers have been widely used in the clinic since the 1970s. In the 1990s, with the successful development of new lasers, lasers have been closely integrated with medical and biological tissue science, and the scope of research has been expanding.
Nd:YAG lasers have the advantages of high gain, low threshold, high quantum efficiency, small thermal effect, good mechanical properties, suitable for various working modes (continuous, pulsed, etc.), and the effect of applying the material interaction in various solid-state lasers is Different, different wavelengths of Nd:YAG lasers work in a continuous, pulsed manner such that the laser interacts with different parts of the biological tissue to obtain a good therapeutic effect. Medical Nd:YAG lasers are widely used in surgery, ophthalmology, dentistry, dentistry, otorhinolaryngology, dermatology, cosmetology, etc., especially in the treatment of skin pigmentary diseases, with unique advantages such as less trauma, better healing, and no scars. This article mainly introduces the characteristics of Nd:YAG lasers and their application in the treatment of skin diseases, so that the reader can understand the performance of various lasers and the therapeutic effects of different types of laser therapeutic apparatus.
