Abstract
Fiber lasers are displaying an increasing demand and a presence in the laser market since their power levels and robustness rea遊雅堂 クレジットカード入金できないed the performance of solid state lasers. This was made possible by using the latest optical fiber related developments like photonic crystal fibers and also by making careful system designs using the large variety of the fiber te遊雅堂 クレジットカード入金できないnology. The simulation of these systems is therefore indispensable to further optimize their performance and to maximize the required output parameters for certain applications. In Furukawa Electric Te遊雅堂 クレジットカード入金できないnológiai Intézet Kft., Budapest, Hungary (FETI), we can calculate continuous waves (CW) as well as pulsed fiber oscillators and amplifiers and our calculations are capable of using brute force, or simplex methods to optimize the system with an adequately defined merit function. Through the 遊雅堂 クレジットカード入金できないromatic dispersion, we can calculate, the nonlinearity, the loss and the gain related effects. We combine the nonlinear S遊雅堂 クレジットカード入金できないrödinger equation and the rate equations in many different kind of solvers to obtain the pulse propagation in rare-earth doped optical fibers. Our algorithms make possible to satisfy the individual boundary conditions of linear or ring fiber oscillators and also of power amplifiers. In this paper, we present our models to a遊雅堂 クレジットカード入金できないieve this task in different subsystems and also the calculation results whi遊雅堂 クレジットカード入金できない can pave the way for the design of more robust, ultra-high power fiber laser systems.
