The World’s Most Powerful Laser Could Unlock Major Scientific Discoveries

EP-OPAL, a laser reaching an astonishing 25 petawatts of power, has received an $18 million grant for development, capable of propelling new discoveries in physics and revolutionary cancer therapies.

Scientists have received an $18 million grant to develop what may become the world’s most powerful laser, called EP-OPAL.

If constructed as planned, this laser could propel new discoveries in physics, emulate conditions of the early universe, and pave the way for more targeted cancer therapies.

The World’s Most Powerful Laser

EP-OPAL would consist of two separate lasers, each reaching an astonishing 25 petawatts of power.

For perspective, this is over 1000 times greater than the total global energy grid, though only sustained for millionths of a billionth of a second when fired.

UC Irvine physicist Franklin Dollar, part of the recipient team, said that while the power levels seem incredibly high already, just a bit more power could unlock many scientific puzzles that are currently intractable.

The project is funded by the National Science Foundation and would be constructed at the University of Rochester’s laser facility, according to the Laboratory for Laser Energetics website.

This breaks the current record held by the University of Michigan’s ZEUS laser at 3 petawatts.

How Powerful is 25 Petawatts?

One petawatt is equivalent to 1,000,000,000,000,000 watts, and that means that 25 petawatts of power is equivalent to 25,000,000,000,000,000 watts.

To put this into perspective, here are some examples of power consumption:

  • The world’s total energy consumption in 2019 was approximately 170,000 terawatt-hours. This is equivalent to an average power consumption of 19,388,127,853 watts.
  • The largest nuclear power plant in the world, the Kashiwazaki-Kariwa Nuclear Power Plant in Japan, has a maximum output of 8,212,000,000 watts.
  • The largest hydroelectric power plant in the world, the Three Gorges Dam in China, has a maximum output of 22,500,000,000 watts.

Therefore, 25 petawatts of power is an enormous amount, one that is not currently produced by any known power plant or facility.

Pushing the Frontiers of Physics

What could such immense laser power enable? The grant outlines four research areas that would benefit:

  • Particle acceleration to probe quantum states of matter
  • Recreating conditions of the early universe
  • Advancing light source technology
  • Exploring laser-driven nuclear physics

Dollar explained that with OPAL, electrons with energies higher than can be produced even at the current largest particle accelerator facilities will be possible.

He added that the researchers would like to test all aspects of quantum electrodynamics, as some phenomena can only be examined at extremely high electric fields.

Potential Cancer Treatment Applications

In addition to expanding scientific knowledge, the researchers believe EP-OPAL could eventually have medical uses.

The high-energy beams may allow doctors to target tumor sites in cancer patients with greater precision.

This could permit higher radiation doses to destroy cancerous areas while minimizing damage to surrounding healthy tissue.

Dollar stated that laser technology is advancing rapidly, and there is no clear limit to how much further it can be pushed.

Next Steps

The lasers would be constructed atop the Laboratory for Laser Energetics at the University of Rochester.

With the NSF grant now approved, the physics community will watch eagerly as the EP-OPAL project progresses.

If successful, this groundbreaking laser could usher in new breakthroughs in multiple scientific domains and pave the way for as-yet unimagined technologies.
