Surgical Lasers

Chemists at Stanford University have developed a non-invasive technique using lasers and carbon nanotubes that visualizes blood flow in the brain, which could help provide powerful insights into strokes and possibly Alzheimer's disease. Current non-invasive technologies like CT scans or MRI visualize...

A team of engineers at The University of Texas (UT) at Austin have designed an optical device that, they say, may offer a fast, comprehensive, noninvasive, and lower-cost solution to detect melanoma and other skin cancer lesions, thereby reducing unnecessary biopsies. Their device is a probe that uses light in...

A research team at the Cockrell School of Engineering at The University of Texas at Austin has created a new nonlinear metasurface, or meta mirror, that may help advance the miniaturization of laser systems for biomedical research and other applications.

Using precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan, Ann Arbor, researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam. They say that their first-time polariton laser is fueled by...

A team of physics researchers at the University of Adelaide, Australia, say that they have developed a new type of laser that will enable advances in areas as diverse as breath analysis for disease diagnosis and remote sensing of critical greenhouse gases.

Microbeam radiation therapy (MRT) provides tremendous promise for cancer patients due to its ability to destroy tumor cells while protecting surrounding healthy tissue. Yet its clinical use has been limited by the size of the massive electron accelerators called synchrotrons needed to generate the...

Tabletop femtosecond lasers are already used in eye surgery, but researchers believe that they may be the future of microsurgery, offering benefits in applications inside the body, ranging from repairing the vocal cords to removing small tumors in the spinal cord or other tissues. Scientists at the University of Texas...
