Picosecond ultrasonics with miniaturized semiconductor lasers [PDF]
Ultrasonics, 2020 There is a great desire to extend ultrasonic techniques to the imaging and characterization of nanoobjects. This can be achieved by picosecond ultrasonics, where by using ultrafast lasers it is possible to generate and detect acoustic waves with frequencies up to terahertz and wavelengths down to nanometers.
