Abstract

Here, the influence of rejection bandwidth of chirped and tilted fiber Bragg gratings on Raman suppression is studied in a 5 kilowatt-level direct LD pumped MOPA fiber laser. A better suppression could be achieved with a broader-band CTFBG, which is quite useful for further power scaling.
