Abstract
We report for the first time, measurements of ultrafast transients from YBC O in which the contributions from a- and b-axis response are separately ide ntified using polarised light. A new signal is observed for E parallel to a which has been obscured in all previous thin film experiments. Comparing t he two contributions we find the new signal to be sensitive to T-c whilst t he signal for E parallel to b exhibits pseudogap behaviour.
