The exposure laser revolution: the success of the high power laser

We must first of its profits.

The laser is a weapon of the field of advanced manufacturing, advanced manufacturing development of a country has a vital role, and the level of advanced manufacturing, reflecting the strength of the overall national strength.

29-year-old became the youngest of Semiconductors, Chinese Academy of Sciences researcher, he is most grateful to his mentor, the Chinese Academy of Engineering Xu Zuyan not only taught to give him a solid foundation of knowledge, but also taught him how to behave.

Crossing the Chasm, is a brand new

In 2005, the graduate school and later to the semiconductor by the Science and Technology Department has just The year the Lin Xuechun received a daunting task - to build all-solid-state light source laboratory.

From scratch, often have to pay unimaginable efforts. Created by the early, Lin Xuechun daytime technology at various transactional work filled to the brim, research can be placed only in the evening to do. High power laser experiments are highly dangerous, water, electricity, light is concentrated into a small area, a little inattentive, splashing out there will be catastrophic consequences, the invisible laser injection burned a hole to put the steel plate. Time, the laboratory, only Lin Xuechun a person at the same time the face of these possible dangers.

Dangerous, Lin Xuechun not afraid, but let his frustration is how to get the ideal experimental results. For a long period of time, he felt very far away from success, think of the Institute for Laboratory invested so much funding might want to go down the drain, he can not help but anxious.

A success is always a good at regulating their emotions. Soon, he suddenly see the light, to make achievements must be calm, determination and courage of the fearless. He put a laser components apart, repeatedly contrast each parameter, careful design of each step, often unknowingly, found that out the window was already broad daylight.

Although tired, he said, would like to thank the period of time, because the daily insistence, he not only see their own progress, to exercise their own will, "Whether encounter any difficulties are not afraid, with the past difficulties encountered than much smaller. "

Across the divide, the results followed. Laboratory breakthrough after another 3kW, 4kW, 6kW and 8kW laser output, shortening the gap with the field of international. In 2008, the assumed project responsible person with Lin Xuechun as "863" key project "high power 5 kW solid-state laser," the subject of high-power solid-state laser research "by the Ministry of Science and Technology Expert Group rigorous assessment, this is the first time China 5-kilowatt solid-state laser successfully developed to meet industrial needs, and have completely independent intellectual property rights. This achievement is of great significance, laser advanced manufacturing equipment engineered to break the international embargo.

Enter "laser Revolution"

The history of human civilization is the history of a human use light, laser is by far the brightest light, laser revolution "in changing the world. Let their manufacture laser services in the community, in this "revolution" achieved little results, Lin Xuechun biggest wish.

In recent years, in order to speed up the transformation of scientific and technological achievements, Lin Xuechun its research team of industrial applications demand-oriented, developed a series industrialized high stability, high reliability lasers and their equipment, are widely used in laser welding, surface treatment, precision machining and laser medical field and achieved remarkable results.

They have developed the high stability of all-solid-state laser metrology institute as a standard light source of domestic power meter calibration. They also developed a leading 1000W quasi-continuous (90ns) solid-state lasers for ship paint removal rust industry, currently used in Singapore IDI Laser Co., Ltd..

Lin Xuechun its research team developed an all-solid-state high-energy pulse (12J / pulse) laser texturing on the metal surface, so laden heavy rail normal driving in rain, snow and other inclement weather, the technology is expected to be applied to high-speed The railway, which will greatly enhance the operational capability of China's high-speed rail in inclement weather.

Of Lin Xuechun team developed for industrial use 1 ~ 5kW high-performance serialization of all-solid-state lasers in successful achievements into Jiangsu Province the Danyang City Tiankun Group signed agreements in 2010, Institute brought the cash income of 20 million yuan. This technology will be widely used in the automotive, marine, aviation, railway pivotal role in the national economy from the field of materials processing, as soon as possible to reverse the situation of our country in the field of advanced manufacturing key outfit basically rely on imports, improve the technological innovation capability .

Nevertheless, the young Lin Xuechun consistently humility: "We only under the guidance of the older generation of scientists to do work for reference., In the future, there are many things waiting for us to do." Renowned achievements of young scientists , which is commendable.
