Research abstract
Theoretical and experimental study of coherent combining of the beams of fiber lasers is proposed. The key element of the proposed scheme is the use of new corner geometry of Volume Bragg Gratings (VBG) for mixing of the field amplitudes of individual lasers and for the coherent feedback. The development of the technology of recording such corner VBGs is proposed. Software package for computational study of coherent combining via corner VBGs is to be developed. Demonstration of coherent combining of CW fiber lasers with YB doping is proposed. BENEFIT: The successful implementation of the proposed work will pave the road to creation of high power continuous-wave composite multi-fiber lasers with the diffraction quality beams.
