Abstract

Journal ArticleWe have studied the transient electronic response of YBa2Cu30y . 5 epitaxialy grown HTC superconductor thin films in the femtosecond time domain, using transient photoinduced reflectivity (∆R) with 60 fsec time resolution. For temperatures T>TC only a bolometric signal was observed with ∆R>0. For T0. The results for T<TC are explained in terms of quasi-particle (QP) electronic response giving ∆R<0. Thus the femtosecond rise time is interpreted as avalanche multiplication of QP across the gap 2A and the subsequent picosecond relaxation as QP recombination. The QP optical response is explained within the two fluid model
