KOCHI: A "subpicosecond" laser system was officially inaugurated at the Centre of Excellence in Laser and Optoelectronic Sciences (CELOS) in the Cochin University of Science and Technology (Cusat) on Saturday.

Vice-Chancellor P.K. Abdul Azis inaugurated the system. CELOS authorities claimed that Cusat had become the second university in the country to acquire such a system.

The system produces 80 femto second laser pulses at a repetition rate of 1,000 pulses per second. When focussed, this laser beam is capable of producing Terrawatt of pure light power at the focal spot of the beam.

Atoms and molecules in the focal spot virtually explode under this intense laser field and they undergo explosive ionisation giving rise to many interesting physical and chemical phenomena.

The new system is one of the most advanced and powerful lasers available in the world. It was imported from the U.S. at a cost of Rs.1.5 crores.

Director of CELOS C.P. Girijavallabhan said that the system would be operated as a national facility for the benefit of research workers from all over the country.
