1. Pulse shaping apparatus, comprising:

  • a source of input laser pulses;

    means for spatially dispersing frequency components of each of said pulses;

    means for collimating the dispersed frequency components to produce collimated frequency components;

    an acousto-optic modulator (AOM) positioned in the paths of the collimated frequency components;

    means including a transducer for applying modulated radio frequency voltage waves to said acousto-optic modulator;

    means for focussing the collimated frequency components after they have passed through the acousto-optic modulator; and

    means for forming shaped pulses of light from the focussed collimated frequency components.
