A four-arm Nd:phosphate glass laser system is being built and is being test
ed. Major design features include Nd:phosphate glass rods up to a diameter
of XO mm and a disc amplifier system of diameter 100 mm. The system has a s
equentially-relayed and spatially-filtered architecture. Since this project
is a technology demonstrator, the main aim of this project has been to dev
elop indigenously Nd:phosphate glass rods and discs and the dielectric coat
ed optics for this laser. A program has also been taken up for large diamet
er deuterated KDP pockels cells and harmonic converters. (C) 1999 Published
