In the process that promotes photoelectricity industry to develop quickly in future, laser technology and the band that other technology uses a field have the following side: 1.

Laser is chemical: Traditional chemical procedure, it is commonly mix reactant together, often need to heat next (or even pressurization) . Heating defect, depend on an element producing irregular motion because of increasing energy, this kind of motion destroys original chemical bond, union becomes new key, and the key that these irregular motion are destroyed or arises, meet what the chemistry that block up anticipates reacts undertake. But if use laser to direct chemical reaction, can overcome afore-mentioned irregular motion not only, and still can score bigger gain. Because laser is being carried,this is height is centered and even energy, on the key that can be made accurately in the element, what use different wavelengh for instance is ultraviolet laser, hit on the element such as vulcanization hydrogen, change the two phasic difference that stimulate beam of light, controlled this element rupture process. Also can use the method that changes laser pulse weaveform, hit energy very accurately on molecular body with effective ground, spark some kind of expectant response. The application of laser chemistry is very wide. Pharmacy industry is the domain of the first benefit. Application stimulates actinic technology, can quicken the synthesis of medicaments not only, and can be in the by-product get rid of that does not need aside, make certain pharmaceuticals becomes more on the safe side, the price also can be reduced a few. Be like again, use laser to control semiconductor, can improve new optical switch, improve computer and communication system thereby. Although laser chemistry still is in start level, but its foreground is very bright. 2.

Laser medical treatment: Laser is two kinds big in the applied cent on medicine: Laser is diagnosed treat with laser, former be regard information as carrier with laser, latter regards energy as carrier with laser. Come for years, laser technology already made the efficient instrument of clinical cure, also make the crucial technology that development medicine diagnoses. It solved a lot of difficult problem in medicine, made contribution for medical development. Now, in basic research, new technology development and new facility are developed and all many sided such as production maintain last, powerful development momentum. The outstanding application of current laser medicine considers to basically express the following now respect: Joint of laser of; of operation of lens of thorax of laser of; of operation of lens of abdominal cavity of laser of; of operation of endoscope of fiber of laser of; of beauty culture of laser of; of benign hyperplasia of prostate of treatment of laser of; of art of corneal figuration of laser of accurate element of; of disease of heart and vessels of treatment of laser of; of cancer of law of smooth motivation cure lens operation. Near future of laser medical treatment studies the key includes: (1) studies the action between laser and biology organization concerns, the research of working relationship; between the laser that already obtained important applying in a lot of and effective treatment especially and biology organization is different laser parameter (include way of density of density of wavelengh, power, energy and movement to wait) the action that to different live thing organization of organ of organization, human body reachs pathological changes to organize concerns, the 　 of data; 　 that acquires a system (the cellular biology effect of 2) research weak laser and its action mechanism, include; weak laser and cellular biology appearance (gene adjusting control and cellular wither die) the molecular biology mechanism of analgesia of relation, weak laser and immunity of losing laser and cell (fight poison of bacterium, antitoxic, disease-resistant to wait) 　 of 　 of; of relation and its mechanism (, develop actively other technology of new laser medical treatment. (4) is right in medical photon technology important, novel photon parts of an apparatus and instrument setting undertake the gender studies developing, for example: Development is medical semiconductor laser system, corneal figuration and hemal figuration use hairdressing of equipment of accurate element laser, laser (change a skin to knit, establish is sent) equipment or equipment of other new laser, those who develop new job wave band is medical laser system and development Ho: YAG reachs Er: YAG laser scalpel. 3.

Super- exceed powerful laser quickly: Super- exceed powerful laser quickly main with flying the research of second laser and application are given priority to, regard a kind of distinctive science as the tool of research and method, the main application of flying second laser can be generalized for 3 respects, fly namely second laser is in exceed the application inside fast domain, in exceed strong field the application inside and the application in exceeding imperceptible treatment. What what flying second laser removes in exceeding fast phenomenon to research a field is the action that a kind of quick procedure diagnoses. It is OK that flying second laser mixes to exceed " of high-speed " camera like a very careful clock especially nature in especially the analysis of a few quick procedures on level of atomic, element, record comes down. The application of flying second laser in exceeding strong field (call strong field physics again) the peak value power of the flying second pulse that ascribe has certain energy and light intensity are very OK tall. The electric magnetic field of correspondence of such strong smooth place will be ambitious the coulomb field in atom, flake the electron in atom easily completely thereby go out. Accordingly, flying second laser is research atom, molecular system is high-ranking the main tool of process of nonlinear, much photon. With flying second laser corresponding energy density is only in nuclear explosion just may exist. Flying second can use ray of X of generation be concerned with and other by force solely the light of extremely short wavelengh, can use at the research of controlled nuclear fusion. Flying second laser is machined imperceptibly with Yuchao is flying second laser the fundamental application that fast phenomenon studies and exceeds technology of laser of another besides strong phenomenon research flying seconds with Yu Chao studies domain. This one application just begins development to rise in last few years, already had many significant progress at present. Exceeding what exceed strong research quickly to differ somewhat with flying second with flying second is flying second laser exceeds imperceptible treatment and advanced production the technology is close together and relevant, the progress that produces a technology to certain and crucial industry can rise directer urge action. Flying second laser exceeds imperceptible treatment is one of industry of current world laser, photoelectron very conspicuous forward position study way. 4.

New-style laser studies: Laser range finder is the starting point that laser uses on the military affairs, use its artillery system, raised artillery to shoot precision greatly. Lidar photograph is compared at radio radar, because laser diverge part is small, directional good, accordingly its measure precision to rise substantially. As a result of same reason, lidar is nonexistent " of " blind area, accordingly especially appropriate at initiative to missile phase dog measure. But because atmospheric is affected, lidar is not searched inside big range aptly, what still can regard radio as radar only is strong and complemental. Still have missile of accurate laser control and guide, and the laser weapon technology that uses on sciamachy field is applied. On the battlefield of maneuver of laser actual combat, be exactly like real battle scene. The advantage; of laser weapon need not undertake ballistic computation; is operated without recoil; handy, for emergency use is flexible, wide; of scope of application does not have radioactivity pollution, effect cost is compared tall. The classification of laser weapon: Different power density, different output is undee, the laser of different wavelengh, be in with interaction of different goal material when, meeting generation is killed and wound differently destroy effect. The sort of laser is various, name each different. Distinguish by working medium, have solid laser, liquid laser and member at present model, ion, accurate element aeriform laser. By its emissive position can be divided it is day radical, Liu Ji, carrier-borne, Che Zaihe airborne wait for a type, by its utility still can be divided for tactics model with the strategy model two kinds, namely tactical laser weapon and strategic laser weapon.
