Paper Abstract

We present recent developments regarding fiber Bragg gratings for kilowatt-level fiber lasers. First, we show that writing grating reflectors through the fiber coating using an ultrafast laser improves reliability and enables higher pump power handling. The use of ultrafast laser technology also offers more options to produce gratings in larger core fibers. Finally, we show that Raman suppression gratings are a good solution for SRS mitigation with their large (<20 dB) rejection over 15 nm and low reflectivity at Raman wavelengths, and negligible insertion loss at the laser wavelength.
