Researchers use lasers to display ‘true’ 3-D objects

Researchers use lasers to display ‘true’ 3-D objects

June 29, 2017

3-D displays, once only found in science fiction, are now closer to reality using a 3-D volumetric display where viewers can see images in three dimensions without the use of special glasses or filters.

Imaging at the speed of light

Imaging at the speed of light

March 13, 2017

Chunlei Guo and his team have used lasers to make materials extremely water repellent. Now the researchers can visualize, for the first time, the complete evolution of micro- and nanoscale structural formation on the material’s surface.

A first for direct-drive fusion

A first for direct-drive fusion

September 6, 2016

Experiments have created the conditions capable of producing a fusion yield that’s five times higher than the current record laser-fusion energy yield. The new work represents an important advance in a long-standing national research initiative to develop fusion as an energy source.

Using power of optics, scientists make predictions about breast cancer

Using power of optics, scientists make predictions about breast cancer

December 1, 2015

A University biomedical engineering lab has discovered a new way to judge whether breast cancer cells are likely to spread, by viewing tumor biopsies with a powerful multi-photon laser microscope and watching for certain optical patterns emitted by cancer.

Funding aimed at fusion energy awarded to Laboratory for Laser Energetics, Sandia National Laboratories collaboration

Funding aimed at fusion energy awarded to Laboratory for Laser Energetics, Sandia National Laboratories collaboration

June 30, 2015

The award seeks to build upon recent successes of Sandia’s Magnetized Liner Inertial Fusion (MagLIF) concept. The concept uses a laser to heat fusion fuel contained in a small cylinder as it is compressed by the huge magnetic field of Sandia’s massive Z accelerator.

Generating broadband terahertz radiation from a microplasma in air

Generating broadband terahertz radiation from a microplasma in air

April 24, 2015

Researchers in the Institute of Optics have shown that a microplasma created by focusing intense laser pulses in air emits not only visible light, but also electromagnetic pulses at terahertz frequencies that can be used to detect complex molecules, such as explosives and drugs.
