A team of scientists have developed the world’s sharpest laser costing 44 million euros. Named as 'Super Laser', it is 10 times more powerful than any other on the planet and has the potential to revolutionize engineering in aeronautics, power and automotive industries.
The Physical Review Letters journal published about the development of Super Laser on 29 June 2017.
This laser was developed within the scope of a nearly 10-year-long joint project with researchers from Physikalisch Technische Bundesanstalt (PTB) and JILA, a joint institute of the National Institute of Standards and Technology and the University of Colorado Boulder in the US.
The new laser is now being used both at PTB and at JILA in Boulder to further improve the quality of optical atomic clocks and to carry out new precision measurements on ultracold atoms.
• Theoretically, laser light has only one colour, frequency or wavelength. However, there is always a certain linewidth. This laser with a linewidth of only 10 miliHertz (mHz) is closer to the ideal laser than ever before.
• It has an average power output of 1000 watts which is a benchmark in sustained high energy pulses and is far greater than the world’s other high-power beams in Osaka and Texas.
• This laser, with record-breaking precision, can help make optical atomic clocks more precise as well as can test Einstein’s theory of relativity.
More than 50 years have passed since the first technical realisation of the laser. Laser light is used in numerous applications in industry, medicine and information technologies. Lasers have brought about a real revolution in many fields of research and in metrology. The first laser was built in 1960.
