Time-resolved detection of propagating Lamb waves in thin silicon membranes with frequencies up to 197 GHz

Guided acoustic waves are generated in nanopatterned silicon membranes with aluminum gratings by optical excitation with a femtosecond laser. The spatial modulation of the photoacoustic excitation leads to Lamb waves with wavelengths determined by the grating period. The excited Lamb waves are optically detected for different grating periods and at distances up to several lm between pump and pr...

The Acoustic Characteristic Investigation of Micro Plasma Shock Wave Obtained by Femtosecond Laser Ablation of Silicon Wafer Surface

We experimentally investigate the acoustic characteristic of micro plasma shock wave obtained by femtosecond laser ablation of silicon wafer surface using F-P optical fiber acoustic sensor with anti electromagnetic interference. The experimental results show that each of the femtosecond laser pulse can only produce a plasma shock wave. Under the different femtosecond laser energy, the acoustic ...

Picosecond time resolved opto-acoustic imaging with 48 MHz frequency resolution.

A compact femtosecond dual-oscillator pump-probe setup with 48 MHz-repetition rate, relying on asynchronous optical sampling, is presented. The relative timing jitter between both lasers over the whole pump-probe delay range is of the order of or lower than 500 fs. We demonstrate that both a picosecond temporal resolution and a 48 MHz spectral resolution combined with the fast acquisition rate ...

Preparation and Characterization of Aluminum Nitride Thin Films with the Potential Application in Electro-Acoustic Devices

In this work, aluminum nitride (AlN) thin films with different thicknesses were deposited on quartz and  silicon  substrates  using  single  ion  beam  sputtering  technique.  The  physical  and  chemical properties  of  prepared  films  were  investigated  by  different  characterization  technique.  X-ray diffraction (XRD) spectra revealed that all of the deposited films have an amorphous str...

Spatiotemporal Imaging of the Acoustic Field Emitted by a Single Copper Nanowire.

The monochromatic and geometrically anisotropic acoustic field generated by 400 and 120 nm diameter copper nanowires simply dropped on a 10 μm silicon membrane is investigated in transmission using three-dimensional time-resolved femtosecond pump-probe experiments. Two pump-probe time-resolved experiments are carried out at the same time on both sides of the silicon substrate. In reflection, th...
