| Abstract | In this work we describe two optical frequency comb systems based on homemade high-repetition rate mode- locked femtosecond Ti:sapphire lasers. One of them uses a laser that has the spectrum broadened with a microstructure fiber to cover a whole optical octave. Its repetition rate can be easily adjusted form 750 MHz to 1 GHz. The other system is based in a ultra-broadband femtosecond high repetition rate Ti:sapphire laser whose spectrum covers a range from 585 nm to 1200 nm (at 20 dB below the maximum) without the use of the microstructure fibers. We have increased the repetition rate from 1 GHz to 2.12 GHz without observing any significant change in the width of the spectrum. The repetition rate of both lasers has been phase- locked to stable microwave oscillators, and could also be frequency tuned in a range of 30 kHz with respect to the reference oscillator. We are going to use these systems in a direct optical frequency measurement technique and in an optical atomic clock based on the Calcium intercombination transition at 457 THz. |

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.
