- Аннотация: A procedure of inspection of mass transfer processes by induced femtosecond laser has been suggested that is based on pump-probe Doppler tomography. In the experiments we used mode-locked Ti:sapphire laser with output power up to 150 mW. Pulse duration was 100fs at 100MHz repetition rate. In our experiments focused laser radiation induced on the surface of the target mass transfer processes (melting and convection). The Doppler shifted backscattered radiation was registered by heterodyne scheme based on Michelson interferometer. We have obtained information about depth and distribution of convection flows within malted paraffin bath with high spatial resolution (Deltaz similar to 15 mum).
