Two-dimensional photoacoustic imaging of femtosecond filament in water

We report a first-of-its-kind optoacoustic tomography of femtoseconds filament in water. Using wide-band (about 100 MHz) piezoelectric detector and back-projection reconstruction technique a filament profile was retrieved. Obtained pressure distribution induced by the femtosecond filament determines...

More Information
Summary:We report a first-of-its-kind optoacoustic tomography of femtoseconds filament in water. Using wide-band (about 100 MHz) piezoelectric detector and back-projection reconstruction technique a filament profile was retrieved. Obtained pressure distribution induced by the femtosecond filament determines the filament location and its radial size with spatial resolution better than 10μm
