Pulse Duration In radar, measurement of pulse transmission time in microseconds, that is, the
time the radar’s transmitter is energized during each cycle.
Pulse Repetition
Frequency
In radar, the number of pulses the occur each second. Not to be confused with
transmission frequency which is determined by the rate at which cycles are
repeated within the transmitted pulse.
Pulsed Power
EMR
Radiated fields that have very high instantaneous peak field strengths or power
density but significantly lower average values.
Pumping The raising of the molecules or atoms of a lasant to an energy state above the
