All-fiber laser pump reflector based on a fs-written VBG

29 Aug 2019 Talbot Lauris Paradis Pascal Bernier Martin

We report on the writing of chirped volume Bragg gratings using 400 nm femtosecond pulses and the phase-mask inscription technique in the pure silica inner cladding of the gain fiber. The usefulness of such fiber component is demonstrated as a pump reflector in a cladding-pumped all-fiber laser... (read more)
