Development Trend and Application Trend of Laser Technology

Laser technology as a core of industrial manufacturing driving force, itself is constantly moving forward. To sum up, the high power laser is toward the "faster, higher, better, shorter" in the four directions.

Laser power is getting higher and higher, the average power has more than 10 million watts. In 2013, the first commercial 100,000-watt fiber laser was installed at the NADEX Center in Nagoya, Japan for the welding of 300mm thick steel plates. Laser cutting applications are also toward a higher power development, laser cutting machine power continues to rise, has reached 8 ~ 12kW.

The beam quality of the laser output is getting better and better, and the beam quality of the fiber laser has reached a single mode of 100,000 watts. In the past year, fiber lasers, disc lasers, direct semiconductor lasers have a significant increase in brightness.

The output wavelength of the blue laser pointer covers a shorter band, and the short wavelength laser has been widely used. Many advanced manufacturing processes require cold processing, such as in the manufacture of smart phones, often need to use short wavelength, short pulse UV laser to deal with. Short wavelength lasers have been widely used in surface marking, semiconductor wafer processing, drilling, cutting and other fields.

The pulse speed of the laser is getting faster and faster, and the ultrafast laser has been developed rapidly. It has been driven into industrial applications by means of simpler structure, more convenient operation, lower cost and more stable performance.

With the enhancement of environmental awareness, a variety of environmental cleaning technology came into being, laser cleaning technology is one of them. Laser cleaning using high-energy red laser pointer beam and the workpiece surface to remove the material interaction, the occurrence of instantaneous evaporation or stripping, without a variety of chemical cleaning agents, green pollution. Can be used to remove paint, oil, oxide, cleaning screw, rust, cleaning weld. Laser cleaning in the microelectronics, construction, nuclear power plants, automobile manufacturing, medical care, cultural relics protection, steel rust and mold decontamination, automobile manufacturing, construction and other fields have a huge market space.

Metal 3D printing is also made of the material, usually using a selective laser cladding (SLM) technology, the use of laser energy to melt the layers of metal powder, and finally made the desired shape. In 2016, SLM system sales of more than 1000, which uses the laser source is mainly fiber laser, disc laser / CO2 laser and femtosecond fiber laser, power range of 30W to 1kW or more. 3D printing of the fine degree is also getting higher and higher, print out the fine structure of the resolution has reached the order of microns.

The next five years, the market will grow steadily, and the main driver of market growth comes from unmanned aerial vehicles, autopilot vehicles, robots, military and security. Part of the green laser pointers lighting market is car laser lighting, mainly car headlights. BMW, Audi and other well-known car manufacturers have adopted a laser lighting system. Another part of the market is safe laser lighting, such as the night environment for people riding a warning sign.

故郷の麦畑

車が高速道路を走って、車窓の麦の畑に限りなく広大な海洋の日光の下で緑の波のうねり。故郷の麦畑が思い出させてくれた。

晩秋の時、1台台のトラクターをピカピカ锋锐のすきの刃を故郷の大地。大地は新鮮で湿った土を露出し、土の中に土の雄渾を瀰漫。人々が持っている鉄馬鍬忙しい整地して畝で、そして木質の昔の種まき車を播洒土地に麦粒。麦の大地に放送して入り、まるで母の懐に入った。それらは土の中でそっと芽吹い、ばんばん土を突き抜けてあける地面、淺い緑の体。人々を眺めて田垄に立っ靑々とした麦の苗は、小柄で可愛い子供たちを眺めて、それらはすくすくと育って、それらを待ち望んで早く出穂注入、生え豊健碩の麦の穂。

麦の苗は二十四節気昼夜止まらない運転に一寸一寸に成長している。大自然のペアが自慢の仕事時間の線はそれらになった毛布紡織緑に覆われて遠い墓穴埌の平原、飾っている蕭条、寒いの村。昼間は淡い日差しが雨露みたいに沐浴ている。それらは風の中で陽気に舞う繊細な腰肢。夜に着いて、大自然のペアが自慢の仕事で寒霜織り成す厚い布団を麦の苗の身で、それらを眠らせて。彼らにとって、激しいの寒さは大自然の福祉を与え、それらの強さを磨き強か気骨を出産した、それらの成熟した夢も。

時間の足音で小寒と大寒を乗り越え、立春の季節になる。春は麦畑に力と希望を注ぎ込んた春。この時の麦の畑のようにスマートな若者は、春に照らされて満ち満ちている生気。春風が吹いてきて、ムギの穂波平原にさかまくような少年たちが、大地に走っているのを呼ぶ。人々は勤勉に働か、血税に麦畑をうるおすている。麦畑は黙々として実を醸して、人々の心の望みを充実させます。

小満芒種ターンが遠のいて行った後で、急いで来た。大自然のペアが自慢の仕事用太陽の七色の光に麦ばたけめっき層の金色。このころの麦畑は豊かで美しく、新進な若者人だ。人々を眺めて旺盛沉实の麦の穂恵比寿が鯛釣りしたよう。人々は収穫麦後、麦粒入れ穀倉として、家族を養うの食糧。

麦畑は、私たちの母です。それは二十四節気の流れで生死交代で、健康、十分であるの食糧は黙って育てた。
