Sub-100 fs time-domain spectroscopy using high-speed ASOPS


Asynchronous optical sampling (ASOPS) was first demonstrated in 1987 [1]. It employs two mode-locked lasers operating at slightly different repetition rates f and f+Δf which serve as pump and probe lasers. Thus the relative time-delay of the pulses from the pump laser compared to the pulses from the probe laser is repetitively ramped from zero to 1… (More)
