Development of high power laser and relevant technology in India

A four-arm Nd:phosphate glass laser system is being built and is being tested. Major design features include Nd:phosphate glass rods up to a diameter of 80 mm and a disc amplifier system of diameter 100 mm. The system has a sequentially-relayed and spatially-filtered architecture. Since this project is a technology demonstrator, the main aim of this project has been to develop indigenously Nd:phosphate glass rods and discs and the dielectric coated optics for this laser. A program has also been taken up for large diameter deuterated KDP pockels cells and harmonic converters.
