主讲人

Professor Vitalyi E. Gusevis a Distinguished Professor at Le Mans University, France. He obtained his Ph.D. and Habilitation in physics and mathematics from M. V. Lomonosov Moscow State University, Russia, and another Habilitation from Le Mans University. His research focuses on the theoretical foundations of nonlinear acoustics, optoacoustics, photothermal, and thermoacoustic phenomena.Prof. Gusev has authored over 365 journal publications and a book titled "Laser Optoacoustics." He has received numerous prestigious awards, including the Lenin Comsomol Prize in Science and Technology, the French Medal of the French Acoustical Society, and the Gay-Lussac Humboldt Research Award. He is also a Fellow of several notable societies, such as the Acoustical Society of America and the American Physical Society.

报告主题

In Le Mans University (France) the research on laser ultrasonics is under progress for already about 20 years. Laser ultrasonics traditionally includes the generation and detection of the coherent acoustic waves by lasers for a variety of applications. In Le Mans University there are certain achievements in applied and fundamental laser ultrasonic research both in the ultrasonic frequency range(MHz, laser ultrasonics, LU) and in the hypersonic frequency range (GHz - sub-THz, picosecond laser ultrasonics, PLU) with the use of nanosecond and picosecond / femtosecond lasers, respectively. The applications of LU to non- destructive testing of the materials and of PLU to characterization of nanostructures and nanostructured materials will be presented.
