Moscow: Though lagging behind US and France in building a laser station, Russia says once its USD 1.5 billion dual-purpose facility is built it will be the world's most powerful.

Though there is no specific date for construction has been finalised but, the station might be built near the Sarov Federal Nuclear Centre in Russia's Nizhny Novgorod region, the head of the nuclear centre, Ildar Ilkayev said on Thursday.

"The Russian leadership made a decision to build the world's largest laser station... The United States has already constructed a similar station and France is about to complete the construction of their own station. We [Russia] are behind them because it costs a lot, but it will be the best one in the world," Ilkayev said.

The laser station will be both used for military and scientific purposes, particularly in the research of laser thermonuclear fusion, which scientists believe to be the backbone of the energy production in the future, he said.

Ilkayev said it would take at least 10 years to build the station.

Describing its potential, he said it will be capable of directing 2.8 million joules of ultraviolet laser energy compared to the output of the US and French stations of two mega joules.

The official also opts for the station, which will be 360 metres in width and as tall as a 10-storey building, to be open for all scientists, including from other countries.

The current world's largest laser system in US, the California-based the National Ignition Facility (NIF), was put into operation in 2009 and it occupies the area approximately to three football fields.

Its 192 intense laser beams are capable of delivering 60 times the energy of any previous laser systems to a target.
