Q-switched short cavity fiber lasers: theory and experiment

In this paper, we analyse the performance of a Q-switched DFB fiber laser comparing theoretical and experimental results

Fiber lasers remains a subject of intensive research because of its importance in the development of integrated telecommunication systems, among other applications (medicine, metrology and industry). Furthermore, a large interest exists on the analysis and applications of distributed feedback fiber lasers (DFB-FL). A special particularity of these robust single mode devices is the extremely narrow linewidth emission under continuos wave operation. Theoretical analysis of DFB-FL have been performed in recent years by some authors. However, few studies have considered the DFB-FL dynamics in a non-stable regime. In this paper, we analyse the performance of a Q-switched DFB fiber laser comparing theoretical and experimental results. Figure 1: DFB-FL model scheme
