Abstract :
Here we study electron relaxation in two high-Tc cuprate superconductors, where EPI is expected to be strong. We use sub-20 fs pulses from two synchronized broad-band non-collinear optical parametric amplifiers (NOPAs), in order to improve the time resolution compared to previous experiments.
