Power analysis of optical fiber laser

Abstract

The laser fields are very wide and advance for the coming optical generations. Fiber lasers are worth to play a vital role in the upcoming new uprising of science due to their role in experimental operations and to their strong experimental arrangement for any starter. Different categories of optical laser found for widespread use such as Erbium Doped Fibre laser (EDFL), Ytterbium Doped Fibre Laser (YDFL). We consider about EDFL and YDFL which are made by doping the fibre core with rare-earth elements of Erbium and Ytterbium respectively. The system has been designed to analyze the gain and pump power and output power dependence of the optical laser EDFL and YDFL for various fiber lengths. The output power of YDFL in ring resonator is 40mW and in linear resonator is 25mW, which is better than EDFL which gives 20mW in ring and 10mW in linear. The YDFL gives better output power then EDFL. Ring resonator is better than linear resonator.
