Abstract

We measured the Cooper pair breaking and condensate recovery dynamics in MgB₂ by means of time-resolved optical pump - terahertz probe spectroscopy. The observed photoexcitation intensity dependence of Cooper-pair breaking is attributed to the presence of two superconducting gaps in MgB₂.
