The 7th International Symposium on Laser Ultrasonics and Advanced Sensing (LU2024) is dedicated to the latest scientific results, methodological and technological advancements, and applications of Laser Ultrasound, Optoacoustics, Phononics and light-matter-sound interactions. The symposium was started in order to bring together world leading researchers in this field and offer a forum for those involved with basic researches and industrial applications of laser ultrasonics, bringing a remarkable impact to this field. The LU2024 focused on the laser generation and/or detection of acoustic waves, application to nondestructive testing, ultrafast optoacoustics, innovative instruments and research achievements in biomedical applications, guided waves, advanced sensing including noncontact, micro/nanoscale or nonlinear measurements and so on.
