This possibility arises when the bunch repetition rate and the frequency of the excited wake field are disturbed, which leads to a sequential displacement of the bunches in phase of the wake field excited by them. In our experiments, the frequency of the wake field is fixed and determined by the Cherenkov resonance. The bunch repetition rate was varied by changing the frequency of the Rubin master oscillator of the klystron amplifier. The dynamics of wake fields and driver relativistic electron bunches in a three-zone dielectric resonator under asymmetric injection of bunches is theoretically investigated. Experimental studies were performed on the long-term stability of the operating parameters of an Nd-YAG pump laser with an additional amplifier. The prospect of increasing the output power of a CPA laser system to about 2.8 TW for a pulse duration of 17 fs by optimizing the operating parameters of an existing laser setup is presented.
