- Abstract
- This report describes the development of in-fiber Bragg gratings used as cavity mirrors for fiber lasers. The principal difficulty is to fabricate a 99% total reflector and a 4 % output reflector with similar bandwidths and an identical operating wavelength. Photosensitivity at a light wavelength of 193 nm using an eximer laser and a zero-order-nulled phase mask was used to photoimprint the reflectors directly in Erbium-doped fiber. Two laser cavities were successfully fabricated and delivered to DREV. The long term resistance of the Bragg gratings to high light intensities in a Q-switched laser cavity looks promising.
