green laser pointer also plays a significant role in exhibiting

Recent years, at an annual rate of new homes increased 200-300. 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. 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 (532 nm) 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. This type ofgreen laser pointer has the function of remote control.
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 . As can be fiber optic, in the future, if the 3-micron fiber optical power with the stability of the successful development of the affected area will be used for non-body cavity incision surgery. In addition, rare earth elements Ho: YAG laser has also been started. Laser treatment of cancer in Japan is very active, mainly Ar laser excitation, flash excitation, excimer dye laser excitation. With fiber optic technology, they are non-cut body cavity cancer therapy making new instruments. The appearance color of this kind of green laser pointer is argent.
Also the treatment of vascular stenosis, occlusion, to bring about a revolution cardiac surgery. Laparoscopy has been successfully applied onto the optical track, not an operation of the laser therapy of intra-abdominal disease, the elderly population in Japan has important practical significance. UV excimer beam with good photochemical effects, suitable for non-heat cut, cut, and can restrain the infrared beam cut by the Ministry of the common thermal denaturation and charring, part of the ArF laser (wavelength of 1.3 microns at the corner of Prince iodine solid-state lasers and diode laser excitation of UV excimer lasers is now more carbon dioxide laser power of 500W, and in theory up to 100KW, recent reports have reached 20kW. and its power is bigger, the better, so the carbon dioxide laser in Japan research and development sent to expectations. Effective range of green laser pointer is more than 1000m.
Development of the German laser industry in Europe is the fastest growing laser industry in Germany, especially in laser materials processing is a world leading position. In 1986, Germany proposed a 1987-1992 "laser research and laser technology" funding priorities of the BMFT-funded plan, the five-year period the actual investment of 200 million 62 million mark, funding priorities and allocation of funds as follows: laser and components 36 %, application technology and system integration 48.9%, laser measurement and laser analysis of 12.2%, other 2.3%; that about 72% of the cost for laser materials processing issues (lighting, components, systems and methods). Undertake a research project of the group (FHG, MPG, GFE) 6 个 research institutes, nine large laser center, university research institute of the 30 groups of about 900 researchers to participate. Users just need to simply press the “page down” and “page up” keys of green laser pointer in a wireless way.
During this period the establishment of more well-known institutes and centers are: Fraunhofer Institute for Laser Technology, Institute of solid-state laser in Berlin, Hannover Laser Center, Stuttgart beam applied research center. According to the German Machinery Manufacturers Institute - Alliance for laser materials processing statistics for 1994, sources for materials processing (CO2) and YAG lasers) produced a total of 1364 units, value of 165 million marks, an increase of 13% compared with 1993; laser devices Number of units increased by 39%. Especially for Mark and dental aspects of low power laser is YAG laser appeared disproportionate growth. Therefore, the laser processing technology for Germany, higher than any previous period. green laser pointer can be widely used in various occasions like product demonstration, e-teaching, in meeting rooms or training rooms and so on.
