Dynamics of high repetition rate regenerative amplifiers

Dynamics features of high repetition rate continuously pumped solid- state regenerative amplifiers were studied numerically. A space independent rate equations and discrete- time dynamical system approach were used for system state evolution analysis. Regular single- energy operation, quasi- periodic pulsing and chaotic behavior regions are distinguished in space of control parameters. Diagrams of dynamical regimes comprehensively exhibiting operation features of the system are presented. Seed energy is shown to be an important parameter determining the stability space. Conditions of stable operation are described quantitatively. (c) 2007 Optical Society of America.
