Chinese Academy of Sciences, Institute of Integrated research resources under the command successfully developed a number of solid-state laser source series DUV edge equipment consists of three major components, including the deep ultraviolet nonlinear optical crystal with the device platform, deep UV solid state laser source platforms, and based on these two platforms developed eight new international initiative DUV laser research equipment. Meanwhile, the project core device DUV crystals and devices have implemented small batch production, and initially to create a Chinese 'Crystals - Light - Equipment - Research - industrialization' innovation chains(Best News - Breaking News Updates | Latest News Headlines | Photos News).

DUV laser nonlinear optical crystal, the Chinese Academy of Sciences researchers in the international growth of the first large-size KBBF (boron beryllium fluoride, potassium) crystals, on the basis of a prism coupler invention patents, pioneered the development of the direct harmonic generation DUV laser advanced technology, and fully carry out deep UV solid state laser source equipment development and interdisciplinary applied research, deep ultraviolet laser output is concerned, successfully developed the world's first set of practical, precision in one of the deep UV solid state laser source.

Chinese Academy of Sciences has successfully developed the eight international initiative new DUV laser research equipment, namely, deep ultraviolet laser Raman spectroscopy, deep ultraviolet laser photochemical reaction apparatus, deep ultraviolet laser light emission electron microscopy, DUV laser photoluminescence spectroscopy, deep ultraviolet laser spin-resolved angle-resolved photoelectron spectroscopy, tunable DUV laser photon energy photoelectron spectroscopy, temporal and spatial resolution DUV laser in situ electron tunneling spectroscopy, and energy analyzer based on flight time DUV laser angle-resolved photoemission spectroscopy Currently, it has eight scientific instruments graphene, high-temperature superconductivity, topological insulators, wide band gap semiconductor and catalyst to get other major research areas important results, and in physics, chemistry, materials, information and other fields to create a number of new multi- interdisciplinary frontier.

It is reported that the CAS has been activated DUV equipment industry development work, plans to gradually to the market. Meanwhile, the 'deep UV solid state laser source equipped with cutting-edge research project' in the successful completion of a task, based on the two work to start the implementation, Momentum will develop large cryogenic DUV laser photoelectron spectroscopy, deep ultraviolet laser modulated reflectance instrument, such as six international advanced level of equipment, technical depth to promote the development of deep ultraviolet.

Come on north vietnamese, i thought you are the Gods of everything

What have Vietnam ruled by the uncompetent corrupted north vietnamese ever invented? Just tell me.

 

[HongWu]

Now our enemies tremble in fear!

 

[Masters]

Not a single Indian in here congratulating us.

What does this do in layman term?

What does this do in layman term?

I don't know for other fields but in manufacturing shorter wavelengths on which UV lasers operate allows for greater precision, in layman's terms, they can engrave ever smaller and smaller features and iirc they don't do as much thermal damage. Industries using this would be semi conductor and solar cell makers. Probably more but i can't remember right now.

This is one of the key areas where I want to see an increasing presence by China。

China launches applicable deep UV laser device

By Chen Boyuan

China.org.cn, September 10, 2013

A deep ultraviolet (DUV) solid-state laser device, invented by the Chinese Academy of Sciences (CAS), has recently passed testing, making China the only country in possession of such technology.

"This is a successful example of China independently developing a sophisticated instrument," said the panel which acknowledged the achievement on September 6.

CAS President Bai Chunli said the success embodies the academy's "dedication to major innovation and breakthrough in seeking development." The use of potassium beryllium fluoroborate (KBBF) once bottlenecked the project. KBBF is a non-linear optical crystal that can transform laser light into DUV for use in solid state lasers. Nonetheless, China lacked the proper technology or equipment to cut it into sophisticated prisms.

Chen Chuangtian, a CAS member, joined hands with Xu Zuyuan, a member of the Chinese Academy of Engineering, and turned to the Hong Kong University of Science and Technology for help.

"We were allowed to use their labs because Chinese mainland research institutes did not have similar ones at that time," Xu said, adding that they eventually, after many strenuous efforts, invented a KBBF prism coupling device.

The device marks the world's first-ever output of 1,064-nanometer's 6-harmonic frequency multiplication, shortening the diode-pumped solid-state laser (DPL)'s wavelength to 177.3nm.

Based on the achievement, the pair later managed to develop an applicable DUV-DPL.

A DUV wave refers to the light wave whose wavelength is shorter than 200nm. Synchrotron radiation and gas discharge are among the main non-coherent light sources to produce DUV lasers. A KBBF prism coupling device-based DPL source features a smaller size, higher energy resolution and higher photon influx density.

China produces world's 1st DUV laser with practical use

《DailyEconomic》 2013-09-11 13:31:13

The Chinese Academy of Social Sciences has produced the first deep ultraviolet solid-state laser with practical applications. The institute created eight laser research stations, which have spurred scientific research into such things as grapheme, according to the China Science Daily.

Since the academy produced a boron beryllium fluoride, potassium crystal, in the 1990s, it has been studying how to turn it into a practical laser source. The crystal has a layered structure and is difficult to cut. The cut is necessary to produce the DUV laser.

To solve the problem, Chen Chuangtian, a member of the academy who developed the crystal, partnered with Xu Zuyan, a laser technology expert with the Chinese Academy of Engineering. They conducted their research at the laboratory of Hong Kong University of Science and Technology because China did not have sufficient research equipment then.

The two experts created a KBBF prism coupling device, which successfully produces a deep ultraviolet laser from the crystal. The device has already obtained patents in China, Japan and the United States.

The two continued their research and created a solid-state DUV laser source which was named DUV-DPL, which has been used to enhance synchrotron radiation and high-intensity discharge.

In 2007, China's Ministry of Finance launched a program headed by Chen and Xu to produce eight DUV-DPL devices. An engineering supervision unit was subsequently established to ensure the DUV technology continued to be the most advanced of its kinds in the world.

The eight devices have been used to enhance the production of grapheme, high-temperature superconductors, topological insulators, wide gap semiconductor and catalysis.

A small batch of the KBBF crystals under 2mm have been produced to supply the domestic market, said Zhen Wenshan, a physicochemical researcher and project managers of the Chinese academy. The institute is also trying to put a photoemission electron microscopy device using the DUV laser into production.

Xu said the program will enter the second phase, during which its scientists will begin developing six DUV devices that aims to expand the use of the technology from physics, chemicals and raw materials into the sectors of information technology, biotechnology and natural resources.

Technical Institute of Physics and Chemistry has also allied with KYKY Technology, a subsidiary of the Chinese Academy of Sciences, to industrialize the DUV technology and promote the DUV devices that have been successfully developed in the market.
