Generation of dissipative temporal solitons in ring self-oscillating systems with amplifier klystrons

Theoretical and experimental results are presented that show the possibility of forming periodic pulsed signal sequences with a profile similar to that of bright solitons in a ring self-oscillating system with an amplifier klystron. The generated pulse sequences are dissipative temporal solitons formed in the ring due to the establishment of balance both between gain and loss and between time dispersion and cubic nonlinearity of the klystron. Analytical solutions have been obtained for a generator model with a two-cavity amplifier klystron and an additional cavity resonator, which confirm the possibility of forming these dissipative structures.
