Abstract

This paper uses SeeFiberLaser simulation software to simulate and optimize a new type of double-ended output fiber laser. Using the controlled variable method, the reflectance range of the high reflectivity fiber grating is set to 50%-95%, with 5% Step, change the reflectivity of the low reflectivity fiber grating, step by 2%, respectively simulate the laser output power of different reflectivity combinations. The simulation results show that the double-ended laser output and the power can be controlled by changing the reflectivity of the fiber grating. When the reflectivity of the high-reflectivity fiber grating is 50%, and the reflectivity of the low-reflectivity fiber grating is 5%, The total output power of the forward and backward directions is the largest; when the reflectivity of the two fiber gratings are both 50%, the output power of the front and rear ends of the laser is the closest; no matter which direction the fiber grating reflectivity is increased, the output power in this direction will become lower, the output power in the other direction becomes higher and the total output power becomes lower.
