| Abstract | High-order stimulated Raman scattering has been known for many years and provides an efficient transfer to a tremendously broad spectrum with many lines spreading from the far IR to the extreme UV. The aim to use this broadband spectrum for sub-fs pulse generation raises several fundamental questions: Are the Raman lines phase locked and is the generation of trains of sub-fs pulses or single sub-fs pulses possible? We explore this subject for realistic conditions with ps- and sub-ps excitation, with the account of linear dispersion and the Kerr effect and without the usually applied approximations. We find that SRS does not lead to phase locking. For ps-pulse excitation pulse trains with chirped pulses not shorter than /spl ap/2 fs are generated. With a broadband phase modulator these pulses can be shortened below 1 fs. For shorter sub-ps input pulses we show a novel feature in SRS as the generation of quasi-continuous spectra and the possibility to generate single sub-fs pulses by external phase control. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
