Abstract :
We experimentally observed revival signals of high-order harmonics under field-free molecular alignment by applying chirp-free and chirped laser pulses. The revival signal obtained even with chirp-free laser pulses exhibited linearly dependant spectral phase with respect to frequency, and the slope of the spectral phase changed with the laser chirp condition.
