| . | Picture: Reference and signal spectrometers (front ) and Nd:YAG pump laser (back) As probe light a white light continuum from a 400nm femtosecond source is used. A passively Q-switched YAG laser with 100ps pulse duration serves as excitation source at 500 Hz. It is synchronized to the fs laser system through a programmable delay generator. Time resolution in the ns range is achieved through a high-resolution time delay counter and a shot-to-shot sorting algorithm. The upper limiting time delay is about 800μs, dictated by the repetition rate of the fs laser system. |
