Abstract

A lasing wavelength red shift from the reflection center of fiber Bragg grating in a Yb doped fiber laser has been observed. The wavelength shift is about half of the grating bandwidth and it is not depend on the temperature or the reflection of fiber Bragg grating. Theory of lasing gain profile is used to explore this wavelength shift and it is well coincided with the experimental results.
