In the past, fiber-optic laser applies extensively at telegraphic industry domain, can make the average time to failure of system of low power of high quality single standard achieves about 25 years, ensure after wanting communication technology to install only, OK get sth done once and for ever, need not worry for its at all. As on century of market of telecommunication of 90 time end break down, fiber-optic laser manufacturer already changed working centre of gravity to contented industry to make, the demand of military affairs, medical treatment and spaceflight domain. Need technology of corresponding laser of power of on any account to this one change of other industry from telecommunication, the key should satisfy regular operation and function objective, hold value thereby the one share share of market of processing of data of billions of laser. Of sort of all sorts of fiber-optic laser technology that market on the market at present startling, can satisfy the requirement of all sorts of industry application. The system of low power single standard that power level is less than 200W is labelling in small processing and more and more adoption get in medical treatment application, at the same time this technology also leads stage direction to develop quickly in Xiang Gaogong, won't damage fiber-optic. In addition, its still handle applied open up for laser material new scope of operation. Each manufacturer all rolled out fiber-optic laser system and component. The output power of the commercial range of products that GSI rolls out is as high as 200W, next year can amount to 2 kilowatt, and the product output power of IPG is less than 10kW. The manufacturer such as IMRA, Spectra- Physics Inc, Synchronous Inc and Optigain Inc basically runs low power and short pulse field. Apparent, laser of Chan Moguang fine already took the lead in holding the share of one share market of technology of laser of other low power, with existing CO2 and Nd:Y of lamp pump riversideAG technology competes. The article discusses the key high power the near future of fiber-optic laser technology develops, discuss brigadier of mark of existing and relevant technology to be what raise taller requirement now ceaselessly to the technology to make an industry bring He Chongxin opportunity. Fiber-optic laser designs high power fiber-optic laser is cabinet and reliable, efficiency is changed in quality of beam of light and power (about 20 ％ ) Nd:Y of riverside of pump of respect excel lampAG laser. Fiber-optic laser contains a long fiber-optic laser antrum (about 12 meters) , allocate pump riverside energy along whole length direction. Efficient can reduce heat government issue, and more than heat is OK the edge is entire fiber-optic and abreaction. Silicon of rare earth of major mix into is fiber-optic laser is the Er that is 1550nm and 1060nm about respectively by output or composition of Yb dopant content. Output photograph comparing with 1550nm, taller efficiency can achieve when 1060nm is outputted. Horizontal electromagnetism model distributings by fine core guide baud sex is controlled. What width is tens of micron is narrow fiber-optic and OK realize single standard to operate, and taller fine core diameter can produce more high-ranking pattern. In designing process of stable, responsible fiber-optic laser system, a series of other it is OK to be based on fiber-optic component compose builds sheet piece type " completely fiber-optic " laser antrum. Other document discussed the dominant position of completely fiber-optic design already extensively, among them two main advantages are be aimed without optics and appear optical surface. The mainest in these functional component is pump riverside closes bundle implement with Prague grating reflector. Graph this kind of 1 fiber-optic laser that is our design the sketch map of antrum. Output is fiber-optic use a diameter the core of single standard fine under 10 micron, its can ensure high quality beam of light is outputted. This framework aims to be able to be in construction of water-cooling carbon fin generation is as high as 500W to output power, and reach service life of whole of 100 thousand hours of diode, at the same time can indoors air temperature achieves 35 ℃ compulsive air is used below the circumstance cooling generation is as high as 120W to output power, and dependability and diode comparative. The function of fiber-optic laser system and dependability depend on diode of pump riverside laser. Came 10 years in the past, pump riverside source has realized the much model diode that can produce several tile to output power inside limits of wavelengh of 900 ～ 980nm business is used. Source of some pump riverside has extremely high reliability, its work normally the average time to failure below the condition has exceeded 500 thousand hours. Combine proper redundancy, source of riverside of this kind of pump can use MTBF at compose to build output power to achieve the fiber-optic laser of hundreds tile. What application machines quality of excellent to need model and tall focusing function to implement small body measure at showing personal computer to fetters is microscopical machining craft, these new-style laser can realize commercial application. Come for years, pulse Nd:YAG laser is metallic nicety cut, careful all the time solder and the first selection of bore. Around 1 micron wavelengh, compare with laser of coequal carbon dioxide, mirror of its focusing optics is less, simpler, and can realize smaller spot size. Exceed nicety to show small machining to be opposite the rapid growth that the demand of laser of quality of more efficient, cabinet, tall beam of light promoted fiber-optic laser to develop the work. These laser work around IR spectral area, with traditional laser photograph comparing has a variety of advantages, and small machining is shown newly to apply a respect to have larger latent capacity in implementation. Medical treatment industry is one of applied domains with laser small the most significant cut, fiber-optic laser is replacing Nd:Y of pulse lamp pump stage by stageAG laser. As a result of the following two main reasons, medical treatment device is common very small: It is they need to install narrow area normally; 2 it is its the stuff that make is expensive, reduce dimension to reduce cost namely. Can be in only the good solution that the laser that area of a few micron works is choiceness, costly equipment. The application with the strongest to small cut demand industry of medical treatment equipment may be bracket cut. Bracket is a kind permanent the tube of metal of account of fine, division that inserts artery. Its conduce to outspread artery, dredge blood stream. This kind in inserting sicken coronary artery cylindrical metallic bracket, can make blood restores to fill billabong to connect. Bracket place includes 316L stainless steel or nickel titanium alloy with material (appearance remembers alloy) . Typical diameter of the canal is 1 ～ 10 millimeter, the wall is large about 100 micron. The key is cut width wants small (30 micron of 20 ～ ) , this asks fiber-optic laser needs to provide quality of higher beam of light and laser power stability. Laser Cutting must have higher exterior quality, lesser heat affects area, and without residual. Graph 2 it is the typical bracket SEM after be being cleaned through cut and ultrasonic cleaner micrograph. Use 100W fiber-optic laser to be able to realize freeboard outline precision (<5 micron) without residual cut (width is 20 micron) . Use output of single standard laser and nitrogen to assist gas, cut ply is 0. The typical rate of the 316L stainless steel of 5 millimeter is 5 meters of ／ about minute. Graph 3 it is the speed of stainless steel cut between oxygen and nitrogen comparative figure. Relevant cut data comes from GSI 100W Chan Moguang fine laser. Fiber-optic laser also is the good choice that SMT pattern plate makes. The accurate rough sketch that all sorts of appearance make in the stainless steel of 500 micron of 250 ～ can is in ply. Besides apply to black metal and metalloid chip, fiber-optic laser is in the polycrystalline silicon with deep cut (silicon chip) the respect also has an advantage quite. Polycrystalline silicon material is very fragile, extremely easy in Laser Cutting process burst. Heretofore, nd:Y of pulse lamp pumpAG is used already successfully at cut this kind of material. The cut test that uses fiber-optic laser of single standard 100W to undertake on GSI at first is measured in cutin of edge of cut speed, cut and fine crackle (length makes an appointment with 10 ～ 15 micron) the positive result that the respect obtained special rise with force and spirit making a person. This and use pulse Nd:YAG laser source is very adjacent, just compare Nd:Y because of stripeAG laser needs level of a few amounts, inferior a bit only in brim quality respect thereby a few. Apply Yu Wei to because laser of Chan Moguang fine has quality of tall beam of light,solder, because this is soldering,can come true when black metal and chip of nonferrous metal data very tall solder speed. The chip that uses laser of GSI Chan Moguang fine to had proved to be able to realize titanium and stainless steel, high aspect ratio solders and alveolus solders. The spot welding that fiber-optic laser can use low power odd model at all sorts of material, conduct solder and alveolus solders, these material include steel of mild steel, Inconel, galvanization, aluminium alloy, copper alloy, stainless steel and titanium alloy to wait. Use CW fiber-optic laser to be able to solder only the stainless steel that the biggest ply is 1 millimeter, and use configuration high power, increase model Nd:Y of the high accuracy of control and equipment of complex pulse figuration, low average powerWhat AG laser can improve numerous data is small solder flexibility. Use pulse (pulse figuration) in the correct figuration that time energy changes, the high quality that can realize all sorts of material solders, include the tall reflectance material such as aluminium alloy, copper alloy and different metal stuff among them. Because have quality of very high beam of light and small spot diameter, laser of Chan Moguang fine suits small cut very much. But because its pulse energy and peak value power are at present inferior, and pulse width is very narrow, because this kind of laser is not small solder,receive applied first selection. Apply at macroscopical machining current, all sorts of users still undertake assessment in fiber-optic to high power laser, its basically apply include the industry such as car, aerospace and shipbuilding. In automobile industry, fiber-optic laser solders with Yu Bai automobile body, laser spells solder board and hydraulic forming cut to wait. With Nd:Y of traditional lamp pump riversideAG laser photograph is compared, because fiber-optic laser has quality of superior beam of light and what can be used at automobile industry is remote solder. Apparent, this kind of laser can come true extremely tall solder speed and deepness penetration. But, solve use small spot diameter and quality of tall beam of light to solder the problem that exists when large board still remains to be improved further, be like: Subassembly, more important is the laser that deepness penetrates alveolus arises heterogeneous other people of revulsive plasma ／ . Heterogeneous other people of this kind of plasma ／ can hamper solder shows depth, cause the instability of alveolus of fill of bath center vapour, create thick hole thereby, the material that exceeds 4 millimeter to ply especially such.
