Raman Device

Raman Device

A Raman device has a length of optical fibre, means 102 for introducing pump radiation 101 into the fibre, the fibre having a first optical cavity defined by first and second spatially separate reflectors 104, 115 thereby forming a fibre laser. The device further comprises a plurality of pairs of sp...

description A Raman device has a length of optical fibre, means 102 for introducing pump radiation 101 into the fibre, the fibre having a first optical cavity defined by first and second spatially separate reflectors 104, 115 thereby forming a fibre laser. The device further comprises a plurality of pairs of spatially separate grating pairs 120,121,130,131 which pairs of gratings define an optical cavity for a pre-determined wavelength. The pairs of gratings being arranged in the fibre such that, in use, stimulated Raman scattering occurs, wherein at least some of the Raman scattering occurs within the fibre laser cavity. As an alternative to grating pairs, inter-coupled wavelength division multiplex coupler feedback means may be used.
