| Abstract | A flash-lamp-pumped Nd:YAG laser that contains two laser rods and dual-telescopic elements is investigated theoretically and experimentally. The two intracavity telescopes of the resonator are appropriately chosen and adjusted to achieve a large-volume TEM00 mode inside the laser rods, and to minimize the variational effects of the thermal lens in the rods. The drift of the optimal operating point of the resonator caused by variation in the pump energy is compensated by adjusting defocusing of the two telescopes over a broad pump energy range. It is experimentally shown that our resonator geometry with appropriate parameters obtained the output energy of 560 mJ with 100 #x03BC;s duration and slope efficiency of 3.5#x0025;, at a pump energy of 16J, even though the misalignment tilting angle of the end mirror reached #x00B1;5mrad. The bi-focusing effect caused by the thermally-induced stress birefringence was compensated by a 90#x00B0; quartz rotator. Output energy was increased by 18#x0025; at the pump energy of 16J. The misalignment tilting angle of the end mirror with intracavity telescope was 4 times larger than that without intracavity telescope. |

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.
