The U.S. has a new most powerful laser — and it’s at U-M

A view through the titanium-sapphire crystal that helps to transfer power into ZEUS’s laser pulses. At two petawatts, ZEUS is now the most powerful laser in the U.S.

The ZEUS laser facility has roughly doubled the peak power of any other laser in the U.S. with its first official experiment at 2 petawatts (2 quadrillion watts). “This milestone marks the beginning of experiments that move into unexplored territory for American high field science,” says Karl Krushelnick, director of U-M’s Gérard Mourou Center for Ultrafast Optical Science.

  1. Researchers predict record Gulf of Mexico 'dead zone' due to Mississippi River flooding

    Extreme flooding of the Mississippi River this spring is expected to result in the largest Gulf of Mexico “dead zone” on record, according to a University of Michigan aquatic ecologist and his colleagues.

    Great big trouble for the Great Lakes

    Already under stress by invasive species and pollution, the Great Lakes are now seeing the reappearance of a problem once believed solved: dead zones, where no life survives. Worse yet, climate projections indicate that the problem is likely to grow.

  3. America's heart

    When alumnus Bill Sparrow decided to kayak the entire length of the Mississippi River, he and his wife Laura expected adventure. But they didn’t expect a whole new understanding of their country, its grandeur and its people.

  4. How have you changed?

    The U-M College of Engineering asked students how they have changed since their arrival on campus. The answers are surprising, poignant and inspiring, and they might just get you thinking about your own time in Ann Arbor.

  5. Teeny-tiny antennas

    U-M researchers have found a way to mass-produce antennas so small that they approach the fundamental minimum size limit for their bandwidth, or data rate, of operation. It could lead to new generations of wireless consumer electronics and mobile devices.

  6. The universe may have been born spinning

    Physicists and astronomers have long believed that the universe has mirror symmetry, like a basketball. But recent findings from the University of Michigan suggest that the shape of the Big Bang might be more complicated than previously thought, and that the early universe spun on an axis.

  • Synchrotron in a closet

    For the first time, researchers can study the microstructures inside metals, ceramics, and rocks with X-rays in a standard laboratory without needing to travel to a particle accelerator, according to a study led by U-M engineers. The newly developed laboratory-scale, three-dimensional x-ray diffraction (Lab-3DXRD) opens up more opportunities for student use. (Image credit: Marcin Szczepanski, Michigan Engineering.)

  • Why a next-gen semiconductor doesn’t fall to pieces

    A new class of semiconductors that can store information in electric fields could enable computers that run on less power, sensors with quantum precision, and the conversion of signals between electrical, optical, and acoustic forms. But how they maintained two opposite electric polarizations in the same material was a mystery. Now, a team led by U-M engineers has discovered the reason why the materials, called wurtzite ferroelectric nitrides, don’t tear themselves apart.

  • Researchers unveil bacterial villain behind ‘potent toxin’

    In the warm summertime waters of Lake Erie, cyanobacteria, or blue-green algae, can proliferate out of control, creating algal blooms that produce toxins at a rate that can harm wildlife and human health. Now, researchers have identified the organism responsible for producing the toxins: a type of cyanobacteria called Dolichospermum. (Satellite image of Lake Erie. Credit: NOAA Great Lakes Coast.)

  • Drug that treats flu shows additional benefit

    One dose of the antiviral baloxavir marboxil lowers the chance of transmitting the influenza virus to family members by about 30%, according to research in the New England Journal of Medicine. In a Phase III global trial of baloxavir marboxil (brand name Xofluza) led by U-M epidemiologist Arnold Monto, researchers found the drug significantly slowed the viral shedding that infects close contacts.

  • E-I-E-I-Omics: Genetics, corn, and more resilient crops

    By analyzing DNA from different cells in nearly 200 lines of maize plants, research led by the University of Michigan has revealed insights that could help growers better adapt their crops to a fast-changing environment. The new study, led by Alexandre Marand, reveals previously hidden information about the activity of genes inside different cell types. (Image credit: Alexandre Marand.)

  • Making desalination more eco-friendly

    Desalination plants, a major and growing source of freshwater in dry regions, could produce less harmful waste using electricity and new membranes made at U-M. The membranes could help desalination plants minimize or eliminate brine waste produced as a byproduct of turning seawater into drinking water.

  • How extreme weather threatens nature’s essential services

    How much will strawberry harvests shrink when extreme heat harms pollinators? How much will timber production decline when windstorms flatten forests? How much will recreational value disappear when large wildfires sweep through mountain towns? These are some critical questions that a new computer simulation, modeled at Michigan, is helping answer.
