| Abstract | The summary form only given. In this paper, we present an RF gas discharge excited diffusively cooled CO/sub 2/ laser with a folded optical resonator. In this laser, two slab waveguide discharge regions are constructed by two grounded copper electrodes and a live central copper electrode, which are cooled with tap water. Each discharge region has a size of 500 mmlength/spl times/98mm/spl times/width2 mm height. In the experiments, the slab waveguide regions were excited by a RF transverse gas discharge at a frequency of 93 MHz, a folded unstable optical resonator consisting of a concave mirror with a curvature radius of 6616 mm, a convex mirror with a curvature radius of 4456 mm and two 45 degree incidence flat copper mirror was employed, the output aperture size is 2 mm/spl times/ 32 mm, the four resonator mirrors form a "U" shape optical path. A gas composition of CO/sub 2/:N/sub 2/:He:Xe at a ratio of 19:19:57:5 with operation pressures at 10 KPa was employed. The whole setup of electrodes and optical resonator was enclosed in a stainless steel vacuum chamber. The vacuum chamber was sealed with copper "O" rings. By the use of the above laser head, a maximum of laser power output of over 1 Kilowatts was obtained. |

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.
