Laser Ultrasound

Laser ultrasound is the physical process in which pulsed lasers generate ultrasound waves in a medium or use lasers to generate ultrasound. Lasers can produce ultrasound in solids, gases, and liquids. Due to the advantages of ultrasound such as short wavelengths, strong directionality, and the ability to diffract and scatter when encountering obstacles, ultrasound detection technology has become an invaluable method for non-destructive testing, studying material properties, and structural analysis. It is also widely used in medical diagnostics, geological exploration, and construction engineering.

Beamtech’s Dawa series, Nimma series, and Gama series lasers are suitable for various engineering fields, including defect detection and localization in different materials, monitoring internal damage processes, and studying fracture mechanisms. The mechanical and thermal properties of solid materials, as well as the photochemical reaction dynamics and thermodynamics of biologically active chemical and biological substances, can be effectively studied using laser ultrasound technology, showcasing its features and advantages.

Over the past decade, Beamtech has accumulated significant engineering and technical experience, providing nearly 100 solid-state pulsed lasers as laser ultrasound sources to many research institutions and companies domestically and internationally. The stability of laser output, excellent beam quality, ability to externally synchronize with ultrasound detection equipment, environmental adaptability, and reproducibility of experimental data have all contributed to the successful application of lasers in laser ultrasound.

Additionally, the Tolar series, representing high repetition rate quasi-continuous pulse lasers, can be effectively applied in time-domain resolved ultrasound, industrial online monitoring ultrasound, and ultrasound imaging of biological tissues. Beamtech can also provide custom-designed laser ultrasound excitation sources according to customer needs and collaborate with ultrasound detection suppliers to offer comprehensive solutions.
