ATOMIC SPECTROSCOPY WITH ULTRASHORT LASER PULSES USING FREQUENCY-RESOLVED OPTICAL GATING

摘要

The D-2 absorption line of rubidium vapour was detected using ultrashort laser pulses as light source. By the application of a frequency-resolved optical gating technique using second-harmonic generation it was possible to measure the absorption line in spite of the strong mismatch between absorption linewidth and pulse bandwidth. The experimental results are explained by a theoretical model. [References: 8]
