An international group of physicists from the University of California at San Diego and Extreme Light Infrastructure-Nuclear Physics facility in Romania devised an experiment that uses a tightly focused high-power laser with a peak power density of 5×1022 W/cm2 to generate a magnetic field as strong as that of a neutron star (100 million times stronger than Earth's magnetic field).
China is building a laser that can produce 100 quadrillion watts – about 50,000 times the planet’s total power consumption — a light so intense that it would equal the amount of power our Earth receives from the Sun. Station of Extreme Light At the heart of the Shanghai Superintense Ultrafast Laser Facility (SULF), due to go online in 2025,is a single cylinder of titanium-doped sapphire about the width of a Frisbee. After kindling light in the crystal and shunting it through a system of lenses and mirrors, the SULF distills it into pulses of mind-boggling power, achieving an unprec...
