At 14:00 on May 13, 2024, Professor Fu Hongbing from Capital Normal University came to the University of Chinese Academy of Sciences at the invitation of Professor Huang Hui to give a lecture on the theme of "Exploration of Organic Electric Pump Lasers". The lecture was held in Classroom 108 on the first floor.

      All-solid-state lasers have the characteristics of small size, good monochromaticity, strong directionality, and high brightness, and have received great attention in recent years. Especially today, when the development of science and technology requires the miniaturization and multi-functionality of devices, organic micro-nano laser materials have the advantages of low price, the ability to control the full spectrum of laser wavelengths through molecular tailoring, and the ability to be integrated on a flexible substrate on a large scale. Huge application potential.

      Professor Fu started from four aspects: organic micro-nano single crystal microcavity effect, highly conductive laser gain materials, organic TADF and phosphorescent gain materials, and organic laser excitons. Based on the key scientific and technological issues of laser devices, from the source of material design Starting from the beginning, through precise and controllable self-assembly technology, breakthroughs in the two core technologies of laser gain medium and laser resonant cavity were achieved.

      At present, high-performance laser devices have achieved full spectrum coverage of wavelengths from the ultraviolet region to the near-infrared region; through laser micromachining technology and patterned assembly technology, the design of organic, organic/inorganic hybrid micro-nanocrystalline laser arrays has been achieved ; Realize the design and application of micro-nano photonic devices based on organic micro-nano crystal laser materials. Aiming at the important scientific frontier of organic electrical pump laser, we try to solve its key scientific and technological problems from the perspective of new materials, new technologies and new principles.

      During the lecture, the teacher and classmates actively discussed the content of the report. The report aroused widespread interest among teachers and students.
