Influences of input optical pulses including the control pulse and probe pulse on the switching window of ultrafast nonlinear interferometer (UNI) are studied by numerical simulation and experiment.
Pulse signal of proportional amplifier is sent to counter after reduced noise by window voltage comparer.
