Abstract

In order to achieve the shaping and control of infrared femtosecond pulse, 4f system phase control technology was used and pulse shaping device was set up by experiment. By using pulse shaping, coherent of population transfer of the excited double states in the rubidium atoms system was controlled. The results show that saturation population can be realized in excited double state by controlling the additional phase of pumping pulse. Population of the upper and lower excited state can be reversed by modifying the function of additional phase. Coherent control of population transfer by pulse shaping can also be applied in other atom and molecular systems.
