Heterodyne Optical Sampling for Picosecond Ultrasonics and Nanoscale Heat Transfer
Résumé
We present a novel ultrafast pump-probe system, allowing for a drastic reduction in acquisition time, typically a few tens of minutes for 20,000 frames. We present acoustic waves and heat transfer measurements in nanometric layers.
