Abstract

We probe the mid-infrared conductivity of YBa2Cu3O_7-δ parallel and perpendicular to the CuO₂ planes after 12-fs optical excitation. Quasiparticle excitations and specific lattice modes are traced simultaneously during the photoinduced non-thermal transition to the normal state. The condensate is completely destroyed within 150 fs, while characteristic phonon resonances undergo a blue-shift on distinctly slower times of up to 0.9 ps. The results indicate selective electronphonon coupling and strong lattice anharmonicities.
