The domestic laser industry has formed a complete industrial chain, which is composed of laser crystal, key components, matching kit, laser, laser system, application and development, public service platform and so on.
Laser processing industry in China can be divided into four industrial zones, the Pearl River Delta, the Yangtze River Delta, central China and the central Bohai region. With the emphasis of these four industries, the Pearl River Delta in small and medium power laser processing machine, the Yangtze River Delta with high power laser cutting welding equipment, Bohai high-power laser cladding and solid-state laser, led by Wuhan, the central region is covered with large, medium and small laser processing equipment. With the transformation and upgrading of China's manufacturing industry, some of the old industrial base and small business base, began to transform the high-end manufacturing sector. For example, the Wenzhou laser industry cluster and Anshan vigorously develop the laser industry, etc..

Since the "65" countries have given special attention to laser technology, so there is today's booming China's laser industry. Now, the development of laser technology and industrialization in the world is very fast. Mature technology is more and more mature in gas lasers and applications. In the field of solid state lasers, new materials are emerging, and the new burning laser pointer technology is also developing. To keep up with the pace of development in the world, to provide technical support and Everfount talents for China laser industry support, we must strengthen the construction of laser technology innovation base, especially the construction of innovation base.

On the basis of many results obtained by the past, in recent years, the research on the three levels of system integration and application, high stability of laser and laser model and Realization of industrialization has made a breakthrough, but the industry still needs to solve the problem.
Integration and development of the system integration and development of the core of Wuhan laser processing industry. System integrator is a region, a leading industry development, only the strength of the system integrators grow, the entire industry can be driven up. Integration of system integration is the purpose of each enterprise has its own characteristics and advantages, there is a certain competitive relationship between each other. According to the characteristics of the current system integrators, may wish to set up solid 50mw laser pointer equipment, laser cutting equipment, laser medical equipment, large-scale laser processing equipment and laser processing stations and other forms of system integrators, owners of existing enterprises become the company's investment, in the process of integration of the existing system integrators, the government should play a good intermediary and service roles, create opportunities for enterprises to mature conditions on listing and financing, further optimize the structure of property rights, to lay a good foundation for further development.
Perfect supply chain was born and grow a number of parts suppliers with core technology. The basis of an industry is supported by many parts suppliers. For the Wuhan area, so the parts suppliers should include group optical devices (such as optical lens, focusing lens, reflector and optical fiber etc.), precision machining, laser power and precision of electronic and electrical etc.. At the same time, these parts suppliers should have the core technology of the field, which is important to promote the whole laser processing industry. Supporting enterprises is the basis of an industry, in particular, to master the core technology and have independent intellectual property rights of supporting enterprises, to promote the role of industrial development.

The introduction of a high starting point of digestion, encourage the development of a number of supporting enterprises is the first to encourage enterprises and research institutions cooperation, which is more efficient way; secondly, enterprises should focus on the development of technology trends, continuous innovation; third, development of government through the science and technology project plan arrangement, tax policy and other means to encourage supporting enterprises. Increase market dynamics, which requires systems integrators in the promotion of 1mw laser pointer processing technology and the establishment of market networks have greater investment, including in a certain time to open up overseas markets. Through the promotion of the application, technical radiation and personnel training, in the domestic establishment of laser processing demonstration application of the sub center, processing station, joint venture company, to promote the development of laser processing industry in china.
Capital platform domestic capital: the diversification of equity investment, the introduction of listed companies, state-owned investment companies, private capital; foreign capital: in Wuhan, Optics Valley, China, the proportion of foreign investment in the field of energy optoelectronics is very small. The introduction of foreign capital can start supporting industries to foreign investment, after all the technical advantages in most related with energy photoelectron matching field, and unlike the investment investment system supporting the integration as big; foreign: the proposed state and local governments to establish regional laser processing industry and the increase financial support strength, making full use of the structural characteristics of domestic the economy and society with high efficiency as the goal, application of advanced manufacturing technologies, high efficiency 5mw laser pointer, laser processing production line design and manufacturing with international leading level.

Industrial Applications of Micro Lasers

The combination of silicon materials and light emitting semiconductor materials is expected to help develop a new micro scale laser pointer, which is studied by Keh-Ting Ng Doris and colleagues at the Data Storage A*STAR Institute.

Silicon material completely changed the form of electrical equipment manufacturing. This semiconductor rich is easy to be processed into small components, such as transistors, and method which is used can be extended to the level of manufacturing industry, which makes the production of tens of thousands of components can be integrated on a single chip. Electronic engineers want to further expand the capabilities of these integrated circuits, so that they can create, process and detect light.
These optoelectronic devices can speed up the processing speed of digital information, and can realize the micro scale laser, for example, can be used in bar code scanner. The problem, however, is that the silicon material is not an effective light generator. Ng's team has designed and produced a combination of silicon and light emitting semiconductor green laser pointer, which are indium gallium arsenic compounds (InGaAsP). "Our results show that this method can achieve a high efficiency and compact active optoelectronic device for silicon substrate, that is, using a very thin III-V family of semiconductor silicon layers," Ng said.
One of the important considerations in any laser structure is the ability to capture light within the structure, namely, the ability to capture light in order to further drive the generation of light. In conventional lasers, this is achieved by placing a mirror on any side of the light producing area. Instead, Ng and the team used a cylindrical geometry device. This will capture some of the light that is generated on the wall of the device and force it to spread within the cylinder. This is called whispering gallery mode, because the same effect will occur in a circular room, such as the dome of the cathedral in the sound wave.
The team started using a silicon substrate, they deposited a thin layer of silicon oxide. Thin film with optically active InGaAsP, only 210 nm thick, is individually made, and then bonded to silicon oxide. Then, the team through a number of materials to create the cylinder, with two or three microns in diameter. Three micron devices emit a 30mw laser pointer light at a wavelength of 1519 nm, which is very close to the wavelength used in commercial optical communication systems.
This device has a unique feature that extends the whispering gallery mode to the silicon and InGaAsP regions. InGaAsP can provide light amplification, and silicon can be passive guide light. "The next step, we want to apply these ideas to the devices at room temperature," Ng said. "Operation at higher temperatures will require adjustments to the design and fabrication of the laser."
