Fujian Photoelectron Crystal and Laser Technology Major R&D Platform Accepted Acceptance

In the afternoon of March 1st, the research and development institute of Fujian Province's major research and development platform for optoelectronic crystal materials and laser technology led by Lin Wenxiong, a researcher at the Institute of Hercynian Studies of the Chinese Academy of Sciences, was accepted by experts from the Science and Technology Department of Fujian Province.

“Fujian Province major research and development platform for optoelectronic crystal materials and laser technology” is facing the international frontiers of optoelectronic materials, intelligent laser processing equipment and other major strategic needs of China’s socio-economic development, dedicated to optoelectronic crystal materials and devices, laser technology and their integrated applications Key common technology research in such fields.

Since the implementation of the project, a number of technological achievements with independent intellectual property rights have been formed and transformation of achievements has been achieved, including the development of a new type of fluorinated lithium gallium nitride laser crystal growth and device processing engineering preparation technology to solve the cracking and crystal processing process. Large slenderness ratio device polishing and other issues, to achieve the stable preparation of large-size high-quality cesium lithium fluoride laser crystal blanks; self-developed crystal dynamic mesoscopic defect measuring instrument, effectively achieve the crystal dynamic mesoscopic defect shape, position and distribution density Accurate measurement of other parameters; breaking through the key technologies of high-power continuous fiber laser system integration, developing high-power fiber lasers with output power up to 500W; breakthrough in key technologies such as seed injection locking, RTP resonance scanning, dual wavelength fast agility, and autonomy Developed a resonant pumped 3.3 μm OPO tunable laser that can be used in mid-infrared laser radar natural gas detection systems.

At the same time, during the implementation of the project, it provided technical consulting and diagnostic services for more than 20 related enterprises in Fujian Province; organized 14 professional technical training courses to assist enterprises in completing 456 engineering and technical personnel training; collected 31 technical requirements of enterprises and promoted 17 project achievements. , The completion of scientific research and the company's docking more than 5 items. During the implementation of the project, it also used the platform to newly purchase and rely on the existing equipment and equipment of the unit, and built and improved an open platform for crystal material and device performance test sharing and open-to-face service. The completed external testing service exceeded 500 batches/year for the enterprise. Transformation and upgrading and improving core competitiveness have played an important technical support role.

“Fujian Province's major research and development platform for optoelectronic crystal materials and laser technology” will continue to focus on the needs of the development of the optoelectronics industry in Fujian Province. It will focus on promoting the research and development of key common technologies, further promote the transformation and industrialization of scientific and technological achievements, and serve the structural adjustment and transformation of the optoelectronic industry in Fujian Province. Upgrades provide reliable technical support.
