1. A method for rapidly scanning a first pulse output from a first short-pulse laser and a second pulse output from a second short-pulse laser, comprising the steps of:

  • detecting a difference between the first and second pulses;

    generating a time delay control signal based on said difference detected in said detecting step;

    altering a time delay of the second pulse by changing the frequency of pulses output from the second short-pulse laser based on said time delay control signal, thereby stabilizing the second pulse with respect to the first pulse; and

    scanning the first pulse and the second pulse altered in said altering step, by changing the time delay of one of the first and second pulses in a predetermined manner.
