In the asynchronous optical sampling technique two femtosecond lasers with slightly detuned repetition rates are used to do fast time domain scanning. This is advantageous for ultrafast time-domain spectroscopy that can evaluate carrier relaxation, lattice vibrations, and other collective dynamic phenomena (polaritons, plasmons, superconductivity, phase transitions etc.) in solids, semiconductors and gases.
