Ultrafast Square Pulses

Executive SummaryIt is desirable in many applications to precisely control the output pulse shape for high speed and high power laser systems. A flat top, fist rise and fast fall pulse is a desired pulse shape. In the case of a bandwidth-limited Gaussian pulse, the peak of the pulse is near the threshold but the rest of the pulse is well below the...
