摘要 Quasiparticle dynamics of an optimally doped Bi2 Sr2 CaCu2 O8+δ single crystal is investigated by the femtosecond pump--probe technique. Temperature dependences of amplitude of the photoinduced differential reflectivity and the relaxation time show the evidence of strong phonon bottleneck. The experimental results are analysed by the Rothwarf--Taylor model.
