Abstract: (1471 Views)
In this paper, we simulate the main part of a fiber laser which is the amplifier and a cavity and optimized based on effective parameters. The chosen fiber laser operates in 1908 nm and pumped by diode laser at 790 nm with pump power of 443 Watt. The important parameters such as input pump power, fiber Bragg grating reflectivity (which use as a mirror in laser cavity) and active fiber length determine the amount of laser output power. In this paper, by optimization the active fiber length and the fiber Bragg grating reflectivity (as the end mirror of the cavity) we have obtained the amount of maximum output of fiber laser. The results of this simulation can use for comprehensive design of CW fiber laser and Increase the laser efficiency by optimization the other important parameters of this type of lasers.
