2, Japanese laser industry grows the current situation

Association of Technical Promotion of industry of photoelectron of the Japan at the beginning of 1994 announced 1992-1993 of industry of photoelectron of Japanese laser — year production value, here introduces the case 1993 only. Japanese photoelectricity industry forecasted production value to be 3.785 trillion yen 1993 (if with 110 Japan: 1 dollar is calculated, should be 34.4 billion dollar) , grow 7.9% than the three thousand five hundred and six billion six hundred million yen 1992.
Photoelectron industry includes photoelectron equipment and photoelectron component two parts, among them photoelectron equipment is two thousand eight hundred and eight billion six hundred million yen (about 25.5 billion yuan) , photoelectron component is 976.4 billion yen (about 8.9 billion dollar) .
From the point of the detailed catalogue of photoelectron equipment, CD is one thousand four hundred and eighty-nine billion seven hundred million yen (occupy 53% ) , smooth input exports equipment 846.2 billion yen (30% ) , optical transmission equipment 244.6 billion yen (9% ) , smooth sensor 100.5 billion yen (4% ) , equipment of laser beam machining 42 billion yen (2% ) .
From the point of photoelectron component detailed catalogue, indication component 478.7 billion yen (occupy 49% ) , glow component 1387 yen (include laser, occupy 14% ) , fiber-optic 126.9 billion yen (13% ) , photosensitive component (light is close to component) 111.5 billion yen (11% ) , compound smooth component 57.2 billion yen (6% ) , optical transmission network 16.3 billion yen (2% ) , solar battery 15.7 billion yen (2% ) .
Develop the view of association by American photoelectron industry, the photoelectron that Japan reachs good copy to comprise in monitor, optical storage, glossy news report already exceeded the United States and Europe in the industry, dominant place is taken on the world. The equipment of laser beam machining that also can see Japan from the number above and medical treatment equipment take scale minimum. 37% what ever held total production value of Japanese photoelectricity property in equipment of the laser beam machining at the beginning of 80 time, as a result of light memory, glossy news report, monitor reachs the rapid development of semiconductor laser later, will more than 10 years already produced very big change.
At the beginning of 80 time, japanese industry group uses laser beam machining actively, and escalate arrives solder, drill rod solder. Statistic makes clear, japan occupies course of study of current world go to work to use laser device 30% the left and right sides, laser beam machining is Japan's main base makes one of technologies. Japan shows those who use at material treatment is laser of high-power carbon dioxide and Nd: YAG laser, a few accurate element laser already also were used, and the aeriform laser of new development has wavelengh laser of 10.6 micron carbon dioxide, wavelengh laser of 5 micron carbon monoxide, wavelengh of the iodic laser of 1.3 micron and laser of diode drive solid ultraviolet accurate element laser. Power of present carbon dioxide laser is 500W more, and theoretic can be as high as 100KW, near future report already achieved 20kW. And its power is greater, the effect is better, reason Japan considers to send to development of carbon dioxide laser in order to expect.
