In this paper,a review on the Brillion fiber laser and the development prospects are presented.Photonic crystal fiber （PCF）,as a new type of specialty fiber,possesses unique structure and stress and has obvious advantage in realizing multi-wavelength Brillion fiber laser.Brillion fiber laser are developed into high-repetition-rate and multi-wavelength,high-power and single frequency.Furthermore,taking advantage of specialty fiber,Brillion fiber laser with high stability are generated.
