Surface acoustic waves have become a key phononic technology to probe and control a wide range of excitations in condensed matter. Here wide-passband transducers establish stable phase locking between a pulsed source and electrically generated ``nanoquakes'' on a chip. An inherently stable, yet tunable, phase locking between a free-running pulsed laser and the sound wave is used for time-domain optomechanical spectroscopy of a dynamically strained quantum dot. This technique can be directly…
