The world's new brightest ever laser is almost ready to fire

The Linac Coherent Light Source II (LCLS-II) will be the world's brightest laser, and it's due to be finished not long into 2022.

The next-generation laser made by researchers from the Department of Energy's SLAC National Accelerator Laboratory is almost complete.

The laser will be the world's bright x-ray laser, called the Linac Coherent Light Source II (LCLS-II). It will be approximately 10,000 times as bright as its predecessor, the Linac Coherent Light Source (LCLS). The LCLS became operational in 2009 and can create a beam that pulses light 120 times per second.

In comparison, the LCLS-II will produce one million light pulses per second, a rate of one pulse every femtosecond. The beam will be shot into a series of alternating magnets (known as an undulator) to produce X-rays, which can then be used to take snapshots during experiments. The laser apparatus of the LCLS-II spans two miles (3.2 kilometers) of a long tunnel excavated near Stanford University.

"If you think about a strobe light that goes off 120 times, you see one image. If it goes off a million times in a second, you get a much different image. So you can create a much better movie," said Andrew Burrill, SLAC associate lab director.

Adam grew up watching his dad play Turok 2 and Age of Empires on a PC in his computer room, and learned a love for video games through him. Adam was always working with computers, which helped build his natural affinity for working with them, leading to him building his own at 14, after taking apart and tinkering with other old computers and tech lying around. Adam has always been very interested in STEM subjects, and is always trying to learn more about the world and the way it works.
