= 25 Hz).

Harmonics of Femtosecond Laser Radiation from Laser Produced Plasma Plumes at 1kHz Pulse Repetition Rate
Owing to the overheating caused by avalanching, the pulse repetition rate
is limited to the kilohertz to megahertz range.
Rational modes of operation of CHVIA installation for the tested working chambers take place at amplitudes of pulsed electric field strength E [approximately equal to] 30 kV/cm in the liquid in the working chamber and at the treatment duration of 20 s with high-voltage pulses of duration 300-1200 ns at pulse repetition rate
n [approximately equal to] 400 pulses/s.
As shown in these figures, the removed depth increased with the increase of both pulse repetition rate
and peak power.
Average power of the laser was varied between 4.5-7.5 W, while pulse repetition rate
was fixed as 25 kHz.
225 A peak for one hour using a 250-Hz, 160-ms sine-wave burst and a pulse repetition rate
of 0.5 Hz.
These sounds can therefore be described, not only by their spectral components, but also by the pulse repetition rate
(pulses/s) or interval between the beginning of consecutive pulses (interpulse interval, IPI).
Generators with semiconductor switches provide a pulse repetition rate
of 50,000 pulses per second [3, 4].
