Abstract

An optimized pulse shaping technique was used to examine optical control of two-photon excitation efficiency of an α-perylene crystal in the temperature region from 30 to 290 K. It was observed that a pulse train with a pulse interval of 90 fs and an alternately reversing phase relation increased the excitation efficiency by a factor of 2 for the whole temperature region. A sliding-window Fourier transform of the pulse shape was used to discuss the mechanism of the efficiency increase. It was concluded on the basis of double pulse experimental results that a pulse interval of 90 fs and an alternately reversing phase relation play important roles in the efficiency increase.
