I believe we all know the laser, the laser's original Chinese name is radium. Later Qian Xuesen suggested to rename this radium light as laser. Laser means light amplification by excited radiation.
Laser light is also called laser light, now has been widely used in the field of beauty, medical field, at present, the field of fine arts is also beginning to apply the laser light, people began to use the laser light for fine handicrafts carving, many stages also use the laser has the penetrating power of the dissemination of the effect to beautify the whole performance.
What are the uses of laser light
1, laser light in the beauty, medical, industrial cutting, health care, engraving and other aspects have a wide range of applications. The wide application of laser radium has made a great change in our life. Laser therapeutic instrument, laser irradiator are commonly used in the medical process, due to laser laser penetration is particularly strong, it does not directly contact the material in the material processing, so do not have to fix the material, there is no requirement for the material's softness and hardness, flexibility, etc., so it can be processed on any material, high processing precision, speed, very widely used.
2, laser light applications are countless, in addition to the well-known stage lighting, it is also used as a medical beauty of the main instruments, laser light powerful emission can make female friends of the facial skin more delicate, we often hear the "laser therapy instrument" and other "laser" beginning with the word "laser". We often hear the "laser treatment device" and other "laser" beginning with the word "two" belong to this type of medical products.
3, another application of laser light is laser engraving, laser engraving can be on glass, wood, metal, cloth and other materials to deal with, carving out the required graphics. In the 2010 Shanghai World Expo light fireworks show on the world's top laser light show.
4, laser lights in industrial applications, it is more eye-opening, it can not only accurately cut the glass, but also wood, metal and these natural materials for the right treatment, to achieve the effect of people's satisfaction.
Laser light will hurt the eyes
1, laser light is a laser light, with bright colors, high brightness, good directivity, long range, easy to control and other advantages. We all know that although lasers can create an atmosphere, they are potentially harmful to human eyes and skin, especially the eyes. If you stare at the laser for a long time, it will cause great damage to your eyes.
2, the green laser light commonly used on stage lighting is more harmful to human eyes, generally speaking, the higher the power of the laser light, the greater the damage. And laser light damage to the human eye is cumulative, irreversible, so do not look more.
3, for some small laser pointer, even if the power is not greater than 5 milliwatts, but the same harm to the human eye, not to mention the direct irradiation of the human eye, will cause retinal burns, serious cases can cause blindness. Therefore, if you work in the environment of the laser lamp, you must do a good job of protection measures, and strictly in accordance with the procedures.
Laser lamp to the eyes how to do
1, laser lamp to the eyes is a more serious matter, if a long time to irradiate, the light is caused by retinal burns, heavy cause blindness. Therefore, if the laser light to the eyes must be based on the severity of the measures to be taken.
2, if the low-power laser light to the eyes, such as hand-held laser, especially red, there will be a slight discomfort, it is recommended to rest, avoid prolonged use of computers, cell phones and other equipment, to provide a comfortable environment for the eyes. Also pay attention to diet, supplement some protein, vitamin-rich foods, such as milk, spinach, carrots and so on.
3, if the eyes are illuminated by high-powered laser lights, such as the laser lights used on the stage, at this time, the eyes will experience a sharp stinging sensation, and there may be symptoms of blurred vision, it is recommended to go to the hospital in a timely manner to avoid delaying the condition.
