What are the medical uses of holmium laser?Holmium laser is a solid laser with holmium (Ho:YAG) as the activation medium. It is produced by doping holmium elements into yttrium aluminum garnet (YAG) crystals to generate laser beams under specific energy excitation. The wavelength of holmium laser is

What laser safety glasses should I wear for Class 4 lasers?For Class 4 lasers, the following key factors need to be considered when choosing laser safety glasses:1. Optical Density (OD)High optical density requirementsClass 4 lasers have very high power, and their protective glasses must have a high

The wavelength range of ultraviolet laser is usually between 190 nanometers and 400 nanometers. This wavelength range is shorter than the wavelength of visible light. For example, the shortest wavelength of violet light in visible light is about 400-450 nanometers, while the wavelength of ultraviole

If you work with fiber lasers, it's vital to always wear the correct laser safety glasses and other protective gear.Fiber lasers may cause serious damage to the eyes. The energy of the laser is highly concentrated, especially the high-power fiber laser, which can instantly focus on the retina and ca

When using CO2 lasers, specific safety glasses are required to protect the eyes from laser damage. The optical density (OD) level is considered. The following are the requirements for safety glasses suitable for CO2 lasers:I. Protective wavelengthThe wavelength of CO2 lasers is usually around 10.6 m

1064nm laser can accurately destroy pigment particles in the skin, such as melanin in freckles and sun spots. After the laser energy is absorbed by the pigment, the pigment particles will instantly break up and be gradually metabolized and excreted by the body's immune system. For more complex melas

The principle of laser hair removal is mainly based on selective photothermal effect, which refers to lasers of specific wavelengths, such as 808nm, 980nm etc. Because its wavelength matches the absorption peak of the target tissue (such as melanin in the hair follicles), the laser energy is mainly

Red laser is a laser beam with a specific wavelength and color. Red laser has high brightness and can be clearly seen in darker environments, making it very useful in some occasions where long-distance indication or marking is required. For example, when demonstrating in a large conference room, a r

The principle of laser engraving is to use the characteristics of the interaction between laser beam and material to perform cutting, punching, scribing, shadow engraving and other processing on materials.Laser engraving produces stunning precision but can harm your eyes and even cause permanent dam
