Academician Liu Songhao is a famous optical and laser expert and the first doctoral supervisor in China. He has made many important achievements and made extraordinary contributions in the frontier fields of optics, laser and its applications.
During Science and Technology Week in May and Science and Technology Month in June, it was difficult to interview Academician Liu Songhao because he was too busy. Academician Liu Songhao was invited to give lectures, one after another, which overwhelmed him. Moreover, in the 10 month of scientific and technological activities in Guangdong Province, his popular science books for young people are also in the final publishing stage, and the busy work can be imagined.
Academician Liu Songhao's personal life is over 70 years old, healthy and energetic. He said that science knows no borders, but scientists have their motherland. Science makes human progress and social development, and science can also make the country rich and strong. History has proved time and time again that we will be beaten if we fall behind, so science is a powerful weapon for a powerful country to save the country.
Academician Liu Songhao told the reporter about his personal experience as a child. 1937, during the occupation of Guangzhou, when he went back to his hometown with his grandfather, he saw the Japanese brutally frisk China people and forced them to bow their heads. When he was a teenager, he made a great wish: "Make progress, devote yourself to science, strive for the prosperity of the motherland and win a sigh of relief for the people of China."
From then on, "relieving people's suffering with science and achieving the future of the motherland with painstaking efforts" became the lifelong belief of Academician Liu Songhao. This belief made him step into the threshold of science. In the mysterious and interesting optical world, he tirelessly conducted scientific research and applied it, and made contributions to China's national defense, medicine, agriculture, communications and other fields.
What is science? Academician Liu Songhao believes that science is discovery, that is, the courage to deny past theories. Innovation is the only mission of scientists.
Academician Liu Songhao constantly challenges himself with a rigorous scientific attitude. In 1950s, he focused on the field of optics. The difficulty he overcame was optical glass. He invented a new variety of rare earth optical glass and got rid of the situation of relying on imports.
In the 1960s and 1970s, he studied the field of laser, focusing on the interaction between laser and matter. He provided important parameters and valuable information for the research of laser weapons, and put forward an important development direction, which was highly valued by the Ministry of National Defense.
In 1980s and 1990s, he focused on the relationship between laser and interdisciplinary fields, applied laser spectroscopy technology to biology and medicine, established the first laser life science laboratory in China, and applied laser technology to agriculture and communication fields.
In recent years, with the social attention to the optical field and the change of scientific research environment, the work of Academician Liu Songhao has made a new breakthrough. He organized the establishment of a high-level and powerful optical Industry-University-Research research base and four laboratories with advanced equipment and cutting-edge disciplines. For example, the Laser Life Science Laboratory combines experts, technologies and research methods from different fields, such as physics, laser, biology and medicine. And engage in innovative research in marginal science together. 199 1 year became the provincial key laboratory. In the same year, with the approval of the state, the first postdoctoral mobile station with photobiology as the main direction was established in China. They have played an important role in promoting optical research and industrial development in South China.
At present, Academician Liu Songhao, as the main member of Guangdong Optical Valley Expert Group, has participated in the construction of Guangdong Optical Valley and done a lot of work for the preparation of Guangdong Optical Valley.

On February 7th, 65438, Academician Liu attended the "National Primary School Science Teaching Seminar" in Shunde. More than 200 experts from the Ministry of Education and representatives from Guangdong 10 provinces, autonomous regions and municipalities attended the meeting. Academician Liu attended the opening ceremony and gave a report on "Science and Technology Development and Photonic Technology in 2 1 Century" at the forum that afternoon, and had a pleasant dialogue with the primary school students.
On February 8, 65438, Academician Liu attended the opening ceremony of the Third International Symposium on Energy and Environmental Materials sponsored by Sun Yat-sen University and delivered a speech. During the meeting, Academician Liu had an exchange with experts in energy and environmental materials from all over the world.
During the "Science and Technology Week", Dongshan District of Guangzhou invited two scientists to have a face-to-face dialogue with primary and secondary school students. In this activity, Liu Songhao told the children about the development of photoelectric science and technology and its influence on production and life in the form of multimedia. The students were fascinated and asked him many related questions.
This incident touched Liu Songhao a lot. He feels that he has too much to say and that children need to master and understand too much knowledge. He decided to publish popular science books to arouse young people's interest and dreams in science. His suggestion was strongly supported by Guangdong Association for Science and Technology. With the support of more than a dozen professors and experts, it took them more than 20 days to complete the book "265438+ 100 cases of popular science knowledge in the 20th century". The book introduces the latest scientific and technological knowledge and its application in an illustrated way, so that primary and secondary school students can roam freely in the ocean of knowledge, set up lofty aspirations and become builders and successors of rejuvenating the country through science and education.
This book focuses on the key development of science and technology and related industries in China during the Tenth Five-Year Plan period, including the latest science and technology, cutting-edge science and hot issues. Pointing to the title of "Photonic Chinese Medicine" in the catalogue, he said: "I have spent more than 20 years on this research. There are more than 5000 words on the same topic, but in this book, there are only 300 words. It is enough for children to master relevant knowledge. "
Liu Songhao believes that science should start from an early age, which is similar to art and sports. It is necessary to create learning conditions for young people, such as books, exhibitions, various scientific and technological activities and competitions. Youth is prosperous, and the country is prosperous; Young people are strong and the country is strong.
Academician Liu Songhao has devoted himself to science for 50 years, but he is still pursuing and exploring. ...
