Identification and simulation of optical amplifiers for ultra-short laser pulses

The mathematical description of optical pulse amplifiers for ultra-short laser pulses results in elaborate distributed-parameter models. Their mathematical derivation and adaptive control has been recently presented. The aim of this contribution is to investigate suitable identification methods to optimally reproduce a measured input-output behavior. To keep the computational burden of this identification procedure in a feasible range, particularly for high repetition rates and their strong coupling of sucessive pulses, efficient numerical algorithms are presented.
