Abstract

Technique of residual cladding pump light detection in active fiber is researched, which is used in assembling the fiber laser system. With this technology, a fiber probe is used to detect the pump light leaking from the cladding with fiber’s coating on or stripped. It’s found that there is a linear relationship between leaking light power and pump light power, and the proportional coefficient is measured. Therefore, there’s no need to cut and fuse the active fiber many times to get the best length of active fiber, and it can save the measuring period and experiment expense a lot. Two types of fiber probes are used, tapered fiber probes and bevel fiber probes. The testing results of low light using these two fiber probes are given and the detecting method is verified.
