In this thesis time-dependent configurations are studied in the formalism of first-quantized string. These configurations are exact: solutions of the corresponding two-dimensional conformal field theory can be found. We can compute perturbative string amplitudes and try to understand the interplay between the time-dependent geometry and the quantized string. In a first chapter, we explain why we study these configurations. In a second chapter we describe the perturbative formalism and explain how to solve some of the technical problems we encountered. A third chapter is devoted to the physical description of the phenomena involved in these configurations, to the specific computations we made and to the insights we gained. Eventually, we con...
