Z optoakustičnim pojavom lahko vplivamo na dele materiala globoko pod obsevano površino. Ta pretvori energijo laserske svetlobe v tlačno valovanje, ki se širi v notranjost. S fokusiranjem valov dosežemo lokalno velike amplitude, kar ima velik potencial na področju medicine. Problem obstoječih siste ...

The optoacoustic (OA) generation of pressure waves above the cavitation threshold causes the rupture of the liquid and the formation of dispersed cavities. The OA lenses involved in this process are generally associated with an ultra-short laser pulse to generate high-frequency ultrasound. OA elemen ...
