| Abstract | Excitation of the /sup 3/P/sub 0 /state is detected in optical-optical double resonance via the dark periods in the fluorescence on the fast /sup 1/S/sub 0/ /sup 3/P/sub 1/ transition. The dye laser formerly used to excite this line was recently replaced by a diode-based laser system: a grating stabilized diode at 922 nm, further frequency stabilized onto a Fabry-Perot interferometer, is seeded into a tapered amplifier. Subsequent frequency-quadrupling employing a periodically poled KTP and a BBO crystal, each placed in an external enhancement cavity, leads to the right frequency at 231 nm. For the /sup 1/S/sub 0/ /sup 3/P/sub 0/ transition a resolution of 1.3 /spl times/ 10/sup -13 /has been achieved so far, limited by the frequency instability of the Nd:YAG laser. The short-term frequency stability of this laser has been strongly improved recently. With a new laser setup a linewidth < 5 Hz (FWHM) for integration times /spl times/30 s has been achieved using active vibration isolation platforms for the reference cavity. Recent progress of that work is reported. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
