Abstract
We apply a spatially multiplexed low-noise solid-state dual-comb oscillator delivering two pulse trains at slightly different repetition rates for picosecond ultrasonics measurements. This novel laser delivers more than 2 W of average power per pulse train with 200fs pulses. We characterize the laser performance demonstrating its ultra-low relative timing jitter and relative intensity noise. By employing a high-sensitivity detection scheme we achieve <5e-5 pump-probe detection sensitivity in a single 12-ns-long trace with 250-fs delay resolution and an acquisition time of only 2 ms. We explain how to predict the measurement performance and optimize the data acquisition scheme accordingly. Mehr anzeigen
