Abstract | Summary form only given. Shaped, amplified fs-pulses have applications in the fields of coherent control of molecules and short pulse x-ray generation. For the generation of amplified shaped pulses with high average power, we utilized an acousto-optic shaping device named Dazzler (Fastlite). The acousto-optic wave in the crystal diffracts individual frequencies in the pulses with varying efficiencies, thus creating amplitude and phase modulated pulses. In our experiments, we temporally modify our pulses prior to the stretcher of a chirped pulse amplifier. We have been able to pre-compensate for higher order phase dispersion in the amplification process, which cannot be compensated by a compression grating. Using a feedback controlled adaptive algorithm, we show phase compensation results in a cleaner pulse than grating compression. For each case, we detuned the regenerative amplifier, by changing the number of round trips by one, which has the effect of adding dispersion. With phase-only shaping, phase information is kept through the amplification process, and can pre-compensate for phase distortion in a high peak power CPA-system. |

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.
