Allow ultraviolet light Shu Youliang of the element's good actinic effect, incision of hot sex of appropriate Yu Fei, excision, can check place of infra-red beam of light cuts the “ that establishs an institute to participate in commonly to exceed ” of sophisticated treatment system, mix with accurate element laser namely ionic bundle for central tool, its target is to be in 93 years to grind the hot denaturation of the ministry and char, laser of one part ArF (horny dried meat has around 193nm absorb belt) apply to corneal incision, have the corneal operation of ophthalmic and myopic cure, but whether maintain remedial effect to still have doubt. ArF laser has outstanding bone incision function, there is the land of use force greatly in plastic surgery. Japanese defensive medical university follows molecular laser in clinical try out recently cleared and serious burn (dead) skin organization, time weak point, anguish is little, can control illuminate selectively, do not have ultraviolet excessive and send the new technology of cancerous care.
Wavelengh 780-830nm, the GaAlAs laser of power 10-1200mW uses muscle of palpebral and ophthalmic cataract, unusual treatment, surgical skin fiber of nerve of division of incision, nerve is stretchy restrain, control of temperature of the blood stream that fastens circularly, skin, reduce ache to wait. Before long in the future, semiconductor laser drive is small-sized once laser comes true, application of laser medical treatment will appear leap. Free electron laser will be henceforth the table column of medical treatment domain, it is future medical the delegate of laser equipment. Laser iatrical is main the task is to treat cancer, blame disease to bring good news to treat AIDS, difficulty.
Although research of Japanese laser medicine is more active, but from association of Technical Promotion of Japanese photoelectron industry the statistical number that publishs at the beginning of 1994 looks, japan is medical 1993 the total production value of laser device makes an appointment with 3 billion yen, by at present the dollar is not worth 30 million dollar to the rate of exchange of yen, what share holding in Japanese photoelectron equipment is the smallest.

3, German laser industry grows the current situation

Develop in industry of European area laser the fastest is Germany, especially the position that laser material machines a respect to be in the world to precede. Germany put forward 1987-1992 1986 year " laser research and laser technology " the BMFT that aids financially a key funds a plan, in these 5 years during real investment is 200 million 6 1000 2 1 million mark, aid financially key and funds to allocate for: Laser and component 36% , applied technology and system are compositive 48.9% , laser is measured analyse with laser 12.2% , other 2.3% ; The task that arranges the classics charge of 72% to be machined at laser material that is to say (illuminant, component, system and method) . Assume a task have scientific research group (FHG, MPG, GFE) place of 6 scientific research, 9 large laser centers, the group of 30 scientific research in college institute, make an appointment with 900 researchers to attend in all. The famouser institute that establishs during this and center have: Husband bright with institute of institute of cost laser technology, Berlin solid laser, Hannuowei laser center, Situjiate research center of application of beam of light.
