ABSTRACT:
Reducing the widths of pulses in a beam from a laser by passing the beam through means to rotate the plane of polarization of the beam when a voltage is applied and reflecting the beam back through the means to rotate to a polarizer, the voltage being applied for a length of time equal to the desired pulse width, the portions of the pulses that have passed through the means to rotate when the voltage was applied being deflected by the polarizer into an output beam, the portions of the pulses that have passed through the means to rotate when the voltage was not applied being passed directly through the polarizer without being deflected into the output beam.
