Referring to laser technology applications in defence, Mr Narayanan emphasised new option of electro optical counter measures for low intensity conflict such as counter-insurgency operations. Laser may provide the ultimate solution to the energy needs through controlled thermo-nuclear reactions without the need for nuclear fission explosion, he said.

Terming laser application as one of the most potent emerging technologies, the President said that introduction of laser technology for medical diagnostics such as eye and skin disorder treatment and painless surgery has been most rewarding for the common man. Referring to other key areas of laser applications, the President said that laser technology in a radar mode could be used in environmental monitoring, pollution control and remote sensing. Another significant application of high power laser could be nuclear waste and oil spill clean up, he said.

The President underlined the importance of building a technology base in the country for optimum utilisation of laser applications. To achieve this, Mr Narayanan said, a long-term plan for close cooperation between academicians, scientists and the industry is imperative.

The symposium was organised in collaboration with the Indian Laser Association and was sponsored by Department of Atomic Energy. This symposium was divided into eight technical sessions covering 16 disciplines. Spread over three days, the symposium was attended by about 400 delegates from various parts of the country. About 26 industries exhibited their state-of-the-art products at a specially organised exhibition.
