Paper Abstract

Linear cavity optical fiber lasers have the advantages of small size, light weight, stable mode, and easy large-scale multiplexing. However, due to the spatial hole burning effect in linear cavity lasers, the long linear cavity fiber lasers have the problem of multi-mode oscillation. In this paper, the quarter-wave plate made by polarization-maintaining fiber and the special combination of fiber grating are used to control the polarization of light transmitted in different directions, which reduces the hole burning effect and realizes the laser few-mode output. The laser performance test results showed that the structure have obvious effect of eliminating space burning holes,which played an important role in eliminating the space burning hole of the line cavity laser and narrowing the laser line width.
