Abstract
We present the first measurements of the ultrafast optical response of Tl2B a2CuO6+delta and show that the optical response is clearly sensitive to the electronic groundstate. In the superconducting state its decay can be inte rpreted as following the reformation of superconducting pairs and the dynam ics of quasiparticles near the nodes in a d-mave gap.
