Rise fronts attained values of up to tens kilovolts per microsecond and voltage pulse repetition frequency up to some tens of kilohertz.
Since only moderate pulse energies are needed to drill small holes in nonreinforced polymers (indeed, high pulse energies can damage materials), higher laser power is best utilized by increasing the laser's pulse repetition frequency (PRF).
At 636 pages for about 30 [euro], it will explain, for example, what the French call 'low pulse repetition frequency radar'.
It does this by comparing the incoming signal with an extensive threat library, usually one prepared by the user, that contains the parameters such as wavelength, pulse repetition frequency and pulse width of both hostile and friendly radars.
