Efficient optomechanical mode-shape mapping of micromechanical devices
David Hoch, Kevin-Jeremy Haas, Leopold Moller +4
We demonstrate a method to optically map multiple modes of mechanical structures simultaneously. The fast and robust method, based on a modified phase-lock-loop, is demonstrated on…

Dimensional crossover of acoustic phonon lifetime in -MoSe
P. Soubelet, A. A. Reynoso, A. Fainstein +4
A time-resolved observation of coherent interlayer longitudinal acoustic phonons in 2-MoSe is reported. A femtosecond pump-probe technique is used to investigate the evoluti…
