It is theoretically shown that, when nano- and femtosecond laser pulses act consecutively on a fullerene-containing medium, bleaching of the medium is observed. The dependences of this effect on the parameters of the medium and of the laser radiation have been studied. This effect can serve as a basis for creating optical shutters with a femtosecond response time.
