Academician Yao Jianzheng: The "chaser" for promoting the industrialization of laser technology

Yao Jianzheng, an academician of the Chinese Academy of Sciences, the first batch of experts from the Chinese Science and Technology Think Tank and a member of the review committee, a laser and non -linear optical expert, a professor of Tianjin University, and the director of the Institute of Laser and Electronic Research.

Yao Jianzheng has long been engaged in research on laser and non -linear optical frequency transformation technology, and has developed the theory of high -power double -frequency laser. The accurate calculation theory of the best phase matching of the double -axis crystal is known as "Yao Technology" and "Yao Technology" and " Yao method.

Develop laser humidity sensor

After the laser appears, it has been applied in all aspects of military, medicine, and biology. In 1969, Yao Jianzheng began laser research, which was nearly ten years late than Western ruby ​​laser. Yao Jianzheng said that there are many applications for laser. In terms of medical care, laser can be used to use thrombosis in the blood vessels and treat cancer; in terms of energy, laser can be separated from isotopes and accepts nuclear fusion; in terms of life, laser holographic photos can be anti -counterfeit and increased three -dimensional sense, laser fiber communication communication, laser fiber communication communication The technical information capacity is large and the transmission speed is fast; in terms of environmental monitoring, laser can be used as an atmospheric pollution monitoring instrument.

In 2017, the development of major scientific instruments and equipment development of the Ministry of Science and Technology — the project “development and industrialization of laser high -temperature and humidity sensors for complex working conditions”. Yao Jianzheng is the head of the project expert group. He said that using laser to detect moisture and various gas is a revolutionary technology. Human production and life are inseparable from humidity measurement. For example, studying the formation and prevention of haze, the measurement of humidity is very critical. In the field of environmental protection, the humidity measurement of emission gas directly affects the accuracy of the calculation of environmental protection emissions.

Yao Jianzhen introduced that moisture or other gases with laser have many advantages. First of all, laser does not affect the components and forms of the measured gas; secondly, it can carry out remote non -contact measurement of dangerous gas to ensure the safety of testers. Furthermore, its measurement accuracy is very high and the laser response speed is very fast. Essence He also said that once the laser high -temperature humidity sensor is successfully developed, it can improve my country's humidity monitoring level, improve the accuracy of environmental protection emissions, and reduce industrial emissions. In the future, this technology application prospect is very extensive.

After years of research, Yao Jianzheng completed dozens of scientific research tasks. In 2021, the Weihai Laser and Optoelectronics Information Technology Research Institute was established. Yao Jianzheng was the dean. He led the team to the research and development of laser and optoelectronics and information optical related technologies, and actively promoted laser technology in industrial intelligence equipment, ocean, medical care, etc. Realize industrialization in the field. At the same time, Yao Jianzheng also made outstanding contributions in the aspects of laser downward communication technology, Taihez technology, micro -nano electronic materials and technology. He often said that scientific research should "stand up to the sky." "Dingtian" is to have an international level; "standing ground" is that scientific research results can be used for national economy and people's livelihood, and change the lives of ordinary people.

Taihez Technology escorted public safety

In recent years, Tahez technology has become a popular frontier technology, and it is a research hotspot in the field of material structure exploration, security inspection and communication. In 2015, Yao Jianzheng signed a workstation established by Beijing Aerospace Yilian Technology Development Co., Ltd., and guided many times that the technical development of the Aerospace Yilian Company Tahez An Instrument. After years of technical iteration, Taihez's human security inspection instrument has become increasingly mature and standardized, and escorted social public safety.

In addition, Yao Jianzheng believes that Taihezbobo has a penetrating ability similar to X -rays, but its photon energy is small and will not cause biological lithography. Therefore, the use of Taihezbo for biomedical imaging has the advantages of high safety. Yao Jianzheng suggested: "The cross -integration of physics, biology, medicine, and materials in the field of Tahezbo should be strengthened to promote the research and application of Taihezbo in the field of biomedicine."

Yao Jianzheng said that in the micro field, Taihezbo technology can provide new scientific methods to explain the laws of interaction between macromes and cells; at the macro level, this technology will be the diagnosis, treatment, evaluation of disease diagnosis, treatment, evaluation , Monitoring and early warning and the R & D and production of subsequent drugs have a revolutionary impact. At the same time, he said: "Only by strengthening the cross -integration of disciplines in related fields and joint research can we achieve substantial breakthroughs in this field."

Promote the integration of "government, production, learning, research, and business"

The Internet of Things can connect cities, from the connection between people to people to the connection of people and things. Yao Jianzheng said that in recent years, China has developed rapidly in the field of information. Among them, the Internet of Things industry has entered a period of stable development. He said, "From the Internet to the Internet of Things to cloud computing, big data, virtual reality systems, blockchain, artificial intelligence, this is a steady development process." In Yao Jianzheng, in the future The data is analyzed in integration to inject new wisdom into the urban network space of all things, human -computer interactions, and world network space.

At the same time, Yao Jianzheng believes that the development of the Internet of Things in my country still faces major issues. First, high -end core technologies have not yet achieved essential breakthroughs. At present, 95%of my country's high -end chips rely on imports, while chips are the core of the Internet of Things. The second is that the operating model is severely fragmented. Like a city, the intelligent construction of transportation, tourism, culture, health, and technology lacks unified planning and design.

In this regard, Yao Jianzheng suggested that my country should seize opportunities and accelerate the "three network integration" combined with the integration of the Internet of Things, the Internet, and the mobile communications network to promote the integration and development; improve the infrastructure of scientific research and industrial development; grasp core technology, study business model issues, and issue issues. Realize the true cross -border integration of "politics, production, learning, research, and business".
