LASER TECHNOLOGY IN INDIA
LASER TECHNOLOGY IN INDIA
At present various research institutions are working on various aspects of lasers, like their fabrications, development of laser materials and their applications to various field like meteorology, communications, medicine, isotope separation and in basic researches.
LASER SCIENCE AND TECHNOLOGY CENTRE (LASTEC)
- LASTEC is a laboratory of the Defence Research & Development Organization (DRDO) located in Delhi. It is the main DRDO lab involved in the development of Lasers and related technologies. LASTEC functions under the DRDO Directorate of Electronics & Computer Science.
- LASTEC is the oldest laboratory in DRDO, established in 1950 as Defence Science Laboratory (DSL) which was a nucleus laboratory with the objective to conduct research in frontier areas of physics, chemistry and mathematics with a special focus on lasers and opto-electronics.
- LASTEC’s primary focus is the research and development of various laser materials, components and laser systems, including High Power Lasers (HPL) for defence-applications.
- LASTEC also develops and delivers directed energy weapon systems for the Indian Armed Forces, based on High-power laser technology.
- As a defence technology spin off, LASTEC has also been engaged in the development of lasers for medical and other civilian applications.
Bhabha Atomic Research Centre (BARC)
- initiated an attempt to develop semiconductor lasers in 1964 though at that time laser was in its infancy and its applications were limited.
- The first semiconductor laser in India, was developed at BARC in 1965. This was a major achievement for India. In another significant breakthrough an optical communication link using Indian-made semiconductor laser was established in 1966 between BARC and the Tata Institute of Fundamental Research (TIFR).
Centre for Advanced Technology (CAT) | LASER TECHNOLOGY IN INDIA
- The laser-related activity in the Department of Atomic Energy got a fillip in 1987 when a new research institute called Centre for Advanced Technology (CAT) was established at lndore to carry out major R & D programmes in the areas of lasers and accelerators.
- Since its inception, CAT has made commendable progress in both the areas and is widely recognised as an important R & D centre of India. Even CAT scientists were approached by the Bharat Heavy Electricals Ltd. (BHEL), which makes large steam turbines for power stations, to explore the possibility of repairing eroded turbine blades by laser alloying.
- CAT has also been developing lasers for surgery. It has promoted research in this area in various hospitals through a National Laser Programme. Apart from the surgical CO2 laser, CAT has developed nitrogen laser for medical use.
- Nitrogen laser has been found useful for treatment of tuberculosis. Many patients of TB develop cavities in their lungs which become breeding ground of the TB bacillus. CAT also has a programme on use of lasers in medical diagnosis. It has taken up development of analytical instruments based on lasers.
Raman Research Institute, Bangalore is using laser system in the metrology work for their radio telescope, whereas Central Machine tools institute, Bangalore is measuring the accuracy of machine tools with lasers. LASER TECHNOLOGY IN INDIA
