History

LASTEC is the oldest laboratory in DRDO. It was 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. On 9 April 1960, DSL was shifted to Metcalfe House and inaugurated by then

. Its first Director was S. P. Chakravarti, the father of Electronics and Telecommunication engineering in India, who later founded LRDE, DRDL and DLRL. With time, many DSC activities were given to newly formed, specialized DRDO laboratories. DSL served as a precursor for as many as 15 present DRDO labs, including DRDL, SSPL, INMAS, FRL, ISSA, DESIDOC, DIFR, SAG, ITM etc. In 1982, the laboratory moved to a new technical building in Metcalfe House complex and was renamed as Defence Science Centre. The centre consolidated its R&D activities towards more specific and application oriented areas, such as liquid fuel technology, spectroscopy, crystallography, system engineering, biotechnology etc. DSL now started concentrating in the area of pure sciences such as physics, chemistry and mathematics. The chemistry division developed G-fuel and

The lab was renamed LASTEC on 1 Aug 1999 to emphasize its core focus of laser technology. As of 2020, LASTEC is no longer functional or act as an independent laboratory. All the staff members have been transferred to DRDO labs in Hyderabad.

Application

In the field of high-power lasers, LASTEC works in the following fields: * Chemical oxygen iodine laser * Gas dynamic laser * Hf-Df laser

Areas of work

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. The main charter of the lab revolves around progressing in areas of photonics, electro-optic counter measures (EOCM), low and high-power lasers (HPL). LASTEC also develops and delivers
