摘要

We have designed and built an ultrafast pump-probe apparatus based on a dual-color scheme for the measurement of spin dynamics, via the MOKE signal, with pulse durations in both pump and probe lines of <10 fs. Such temporal resolution is obtained using hollow-fiber and chirped mirror pulse compression techniques.
