Evolution of transient oscillation regimes in monolithic ring lasers

The evolution of the regions of existence and stability of quasi-periodic and chaotic oscillation regimes in a monolithic ring Nd:YAG laser caused by changing the pump power is studied experimentally. It is shown that the dynamic chaos regime appearing upon modulation of the pump power is alternated by windows in which different quasi-periodic lasing regimes take place. A scenario of the passage from the self-modulation lasing regime to dynamic chaos is considered.
