World’s most powerful laser will be sextillion times brighter than the Sun
Powerful lasers are helping us unravel the mysteries of the unverse and do great things, and now they're staggeringly powerful.
Key takeaways
- A single pulse from the laser will deliver more power than the entire UK national grid, in a blast lasting a trillionth of a second on a minuscule target.
- Construction of the laser will take six years to complete, creating a number of jobs in the science sector, as well as for designers, engineers and technicians.

The world's most powerful laser, a 20 Petawatt laser monster which will be at least double the power of the world’s next most powerful laser which is at the LLNL facility in the US, will be built in Oxfordshire in the UK thanks to £85m in new funding for the technology.
Scientists are aiming to develop the technology which will be a "million, billion, billion times brighter than the brightest sunlight" in the world.
It is thought the technology will have practical applications in nuclear fusion, renewable energy and batteries.
The most powerful laser currently at the Central Laser Facility in Oxfordshire is the Vulcan, which is used in plasma physics, and the Vulcan 20-20 will have a 20-fold increase in power with eight additional beams, making it the strongest laser in the world.
A single pulse from the laser will deliver more power than the entire UK national grid, in a blast lasting a trillionth of a second on a minuscule target.
Construction of the laser will take six years to complete, creating a number of jobs in the science sector, as well as for designers, engineers and technicians.
Professor Mark Thomson, executive chair of the Science and Technology Facilities Council (STFC), which provided the funding, said: "The Central Laser Facility has been a driving force behind discoveries that have advanced our understanding of diverse areas from the fundamental properties of matter under extreme conditions to the formation of stars and planets."
Professor John Collier, director of the Central Laser Facility, added: "Vulcan has been the flagship laser at CLF for many years, and widely recognised internationally as a pioneering facility.
"Over the past 40 years, it has made important contributions to plasma physics research and hundreds of PhD students have been trained at the facility.
"It is timely for Vulcan to undergo its next major upgrade, making it ready to serve a new generation of scientists, ensuring the UK retains its leadership role in this field."
The current Vulcan project helped map how COVID infects and damages cells during the pandemic, as well as developing new techniques for security screening in airports.
Science minister George Freeman said: "Re-establishing Britain as home to the world's most powerful laser is an exciting opportunity to explore the unexplored in astronomy and physics, stride towards new clean energy sources for the good of our planet and much more. By investing £85m to give our research community the edge in leading crucial scientific discoveries, we are also delivering hundreds of highly skilled jobs in science and engineering that boost the UK science sector and grow our economy."
