| Abstract | Summary form only. Thin-film microoptical arrays are promising tools for ultrashort-pulse laser beam shaping and characterization. Short optical path lengths, minimum spectral dispersion, low absorption and broadband transmission are advantageous features for the handling of high-power few-cycle pulses. The beam shaping in space, time and spectrum is of great practical interest for many applications (multiphoton excitation, material processing, acceleration, atom guiding, measurement techniques) and also relevant for an evaluation of damage risks. In our experiments, we investigated three different kinds of interference phenomena: (a) free-space interference of converging beams (quasi-Bessel beams with extended focal zones and transversal fringes), (b) self-imaging of array structures (Talbot effect with regular intensity patterns), (c) interference caused by internal reflectance of spatially variable Fabry-Perot etalons (Newton rings). |

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.
