Pulse length is usually expressed in microseconds, but is also measured in kilometers. The terms "short pulse" and "ultrashort pulse" are a bit general--typically 200 picoseconds down to femtosecond level durations--but when the pulse length becomes this short, material removal becomes a function of vaporization or sublimation rather than absorption. the extent of something from side to side. Dictionary English-German Informatics. Here, as the name suggests, the width of the pulse is varied in proportional to the amplitude of the signal. Interpretation Translation  pulse length. Injector pulse width is the amount of time, measured in milliseconds (ms), that a fuel injector stays open (delivers fuel) during a cylinder intake cycle.
