Summary on Grant Application Form |

Ultra-broadband Multifrequency Raman Generation (UMRG) is one of the most novel non-linear optical processes to have emerged over the last few years. Excited by two incident beams (pump and Stokes), a non-linear medium can generate tens or hundreds of equally-spaced Raman lines with an overall bandwidth that can approach the carrier frequency.In the light of our earlier work and experimental results, we propose to develop the theory of the process with particular emphasis on the role of competing Raman processes, the consequences of pump beam detuning, and the potential benefits of UMRG in a cavity environment. The relationship with analogous four-wave mixing effects in optical fibres will be explored. Projects on chirped-pulse Raman amplification and optical parametric amplification, directly relevant to experiments in the TITANIA and VULCAN groups at RAL, and at St Andrews, will also be pursued.Research on the theory of excess noise will continue, in collaboration with experimentalists at the University of Leiden, and will start by extending the analysis to the case of resonators with triangular cross-section.
