Institute of Japanese job creation and heavy industry of 3 water chestnut develop laser of high-power carbon monoxide jointly, came true 89 years successive 4 hours of 5kW, short time amounts to 7kW oscillation output. 93 years its output power to already achieved 20kW, it solders in cut in cutting a figure, and Japanese industry creation studies He Chuanqi weighs labour weighs the iodic laser of high power to be developed together, came true 1989 close infra-red oscillation, it is chemical laser, the feature is oscillation efficiency extremely tall, device of laser of 5kW carbon monoxide, 1kW iodic laser already established the laser that will hold water in April in 92 years to apply labour to learn a center.
In addition, enlarge of laser of solid of arc lamp drive is 3kW, because its are put in power to increase,bring about horn of diverge of beam of light to slant to repeat the defect with low frequency with pulse oscillation greatly, japan is developing laser of semiconductor drive YAG to replace hard. According to report, laser of YAG of 1kW diode drive by making by Japanese national institute.
Current, laser of high-power accurate element and its machine medium application development to consider to arouse people pole large interest in material. It but the treatment that radiothermy grows high-energy photon not to produce caloric element standard. The 18 folk company that 86 years Japan tells courtyard of technology yield a province to put forward and 3 countries make 2kW class Xecl permit molecular laser equipment.
The flexibility of cut of laser beam machining, high accuracy, high rate, high reliability, efficient wait for an advantage, go up in laminose industry not only, and wide also in metal, plastic, ceramics to use. The closest 5 axes or 6 axes three-dimensional laser beam cutting machine implement the person already was in Japan car, mechanical, electric machinery weighs the distinguish oneself in labour.
In the meantime, laser beam welding is received in component of Japanese electron, electric machinery, car, car, OA machine small, large quantities of quantities get developing quickly in production. It is the success on this industrial group product line applied laser beam welding is fixed eyes upon for world place. The Japan in if be made in car bodywork,be being built is bold the new method that uses the punch after laser beam welding is being carried out to receive with respect to will thin stencil steel when having preform to shape (Tailorcd Blank Welding) , already went up for the world now place of manufacturer of great majority car is imitated.
Japan replaced glitter to undertake to solder steel rolling coils controlling steel industry with 5kW and laser beam welding of 10kW carbon dioxide the join of material. Be in thin, medium thick board steel tube, advanced thin model when stainless steel is made, be united in wedlock with photograph of solder of high frequency electric welding, TIG, assured the stability of quality.
Japan devotes oneself to laser to exceed the research that thin plate solders, be like board thick the foil under 100 micron piece, cannot fusion welding, but be able to succeed through having the YAG laser beam welding of weaveform of special output power, indicated the capacious future of laser beam welding. Japan brings those who feel proud is the maintenance that developed canaliculus of generator of the steam in using YAG laser beam welding at nuclear reactor successfully first on the world, this is Japanese utmost favourable geographical position uses YAG laser (1.06 micron of wavelengh) can with quartz fiber-optic remote control is transmitted and collect the becomes greatly sophisticated technology of peripheral. As the high power of 3kW above, Gao Liang will be spent henceforth and control maintainability all of the YAG laser of beautiful and laser of solid of high-power of drive of laser of new generation diode be born, the form a complete set of soft hardware, the laser technology that predicts this one domain still can have new breakthrough.
