| Abstract | Stoichiometric LiNbO/sub 3/ and LiTaO/sub 3/ single crystals have been commercialized by a spin-out company from NIMS called "Oxide Corporation." Stoichiometric crystals are superior to their conventional congruently grown counterparts in almost every respect, and will find widespread use in tele-communications, optical storage and frequency doubling and parametric conversion. Unlike congruently grown crystals which are typically lithium deficient, stoichiometric materials maintain the almost ideal 50/50 lithium to niobium ratio, thereby reducing the defect density by two orders of magnitude. This in turn leads to larger nonlinear and electro-optic coefficients, improved transparency in the UV, increased resistance to optical damage, and most importantly for nonlinear and parametric processes, factors of between 5 and 10 reduction in the poling field required. Commercial availability of these materials has been long awaited, and the expectation is that improved device performance can be expected imminently. |

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.
