The mains switch of the green laser pointer could conveniently cut the power
World laser market can be divided into three regions: the United States (including North America) 55%, 22% Europe, Japan and the Pacific region accounted for 23%. The range of green laser pointer is the laser distance.Japanese market in the world of laser technology top the list in optoelectronics, the United States ranked second; in medical laser and laser detection is the United States top the list;
In the medical laser, the United States is a world leader. Laser medical equipment is widely available not only in the United States, and a large number of exports, the United States, laser medical equipment by the U.S. Food and Drug Administration (FDA) unified management, and only approved registered before use and production, thus ensuring the products of laser medical equipment quality and reliability and security. The range of 100mW laser pointer is usually above 200 meters. According to statistics, 21 million U.S. hospital surgeries have been 2.5 million cases in the use of CO2 laser scalpel, 12% of the total operation, the U.S. National 2 / 3 of outpatient has laser medical equipment. In the U.S. the new laser medical equipment and medical technology continues to occur, for example, disc 20-25 million U.S. patients each year, of which 10-20% can be removed with a laser; the United States, 14 million people who want to remove the tattoo, the United States each year 450,000 patients diagnosed with kidney stones, of which 1 / 3 or with endoscopic laser lithotripsy technology, characterization of the cornea with the excimer laser for vision correction has been made to more than 20,000 cases, 200-300 standards molecular lasers in the U.S. for the treatment of myopia. The range of Blue Laser Pointer depends on the power of itself. The output value of about 8000-12000 million dollars; remove wrinkles is called smooth skin and then laser therapy, the price of each treatment in the United States from $ 800 to $ 4,500 (not including insurance), which estimated the market size of the skin and then smooth up to 15 billion U.S. dollars, has attracted at least eight companies for the smooth skin and then release CO2 laser laser therapy system.
Japan began in Ar laser retinal laser coagulation of medical, surgical carbon dioxide laser knife, medical Nd: YAG laser endoscopy ushered in the first medical laser thermal energy generation. Higher the power of 5mW laser pointer is, larger the range is. With the advances in laser technology, laser therapy was born chemical efficiency, opening up the broad road of medical laser, Today, Japan are all in the medical field of laser applications.
Japan's use of Nd: YAG SHG laser (532nm) of medical lasers, the fundamental power of 60W, tone harmonic power of about 20W, through the KTP wavelength conversion has been widely used in health care.
Er: YAG laser light compared with the 2.94-micron to 10.6 micron carbon dioxide laser is more susceptible to water, Ca, P, etc. are absorbed, used for cutting, removal of more water body incision of soft tissue and bone, the performance is much better than carbon dioxide laser knife.The contactless distance of 200mW Laser Pointer refers to the distance between the emitter and receiver.
