Study of gain efficiency in quasi-distributed amplification systems
Abstract
We propose the mathematical model of quasi-distributed gain in fiber laser systems with cavity dumping. Particularly, we consider in detail the case of a small number of periodic cells in such lasers. The study of the signal gain in Yb-doped active fiber includes the experimental measurement of its characteristics and the theoretical approximations based on experimental results. Theoretical analysis of laser schemes with quasi-distributed gain considered here enables optimization of the output pulse characteristics for various numbers of active fiber cells.
