Summary on Grant Application Form |

Progress in optical fibre technology has opened up the new possibility for extending the method of SPC through SBS to CW laser sources. This offers an attractive approach for generating power scalable, diffraction limited outputs based on rugged and inexpensive state of the art fibre technology. The HWU group, funded by the EPSRC (GR/L95229), pioneered this field with the successful demonstration of high fidelity, polarised SPC of CW and also long pulse laser radiation in multi mode optical fibre, and from this the generation of diffraction limited output in a test of principle CW Nd:YAG MOPA. These developments are the basis for now taking our research through, in collaboration with DERA, to a real application of this new technology for beam clean up of a high power diode pumped Nd:YAG MOPA. In basic science the proposal addresses new behavious of SBS and SPC/SBS in fibres, shown in our earlier work to be generic to the waveguiding nature of these phenomena in an optical fibre. All areas are today points of high interest worldwide, motivated by the needs for laser systems with diffraction limited output, scalable power and controllable operation from pulsed to CW.
