A completely new type of display that creates 3D images by using a laser to form tiny bubbles inside a liquid ‘screen’ has been created by researchers. Instead of rendering a 3D scene on a flat surface, the display itself is three-dimensional, a property known as volumetric. This allows viewers to see a 3D image in the columnar display from all angles without any 3D glasses or headsets. In The…

A material that could reduce signal losses in photonic devices has been developed by engineers at the University of California San Diego. The advance has the potential to boost the efficiency of various light-based technologies including fiber optic communication systems, lasers and photovoltaics. The discovery addresses one of the biggest challenges in the field of photonics: minimizing loss of optical (light-based) signals in devices known as plasmonic metamaterials. Plasmonic metamaterials…

BAE Systems has said it will develop a laser-powered mirage-maker for the military within 50 years. The system, Laser Developed Atmospheric Lens (LDAL), would work by using a ‘high pulsed laser system’ to ionize a specific area of the atmosphere, and use that area to manipulate levels of refraction, reflection or diffraction. Essentially, BAE wants to hand the British military – or anyone that will pay the price and pass…

January 4, 2017

A plasmonic nanolaser that operates at visible light frequencies and uses so-called dark lattice modes has been developed by researchers at Aalto University, Finland for the first time. The laser works at length scales 1000 times smaller than the thickness of a human hair. The lifetimes of light captured in such small dimensions are so short that the light wave has time to wiggle up and down only a few…

It’s hard to believe, but after having unraveled many of the laws that make the universe tick, physicists still haven’t reached an agreement on whether something as seemingly simple as “hot” or “cold” can be measured in a system under certain circumstances. “Imagine you threw an iceberg into the sun and right before it’s melted and gone, you wanted to know, ‘How hot is that iceberg at that moment?’ Would…

A software suite that significantly reduces or eliminates the need for user interface development and maintenance has been released by ACS Motion Control. Designed for high precision laser processing equipment, SPiiPlusSPC (smart processing commander) software provides complete machine control. The software easily integrates, manages, and coordinates the motion control system, laser, and other machine peripherals (vision, galvo, etc.). Leveraging the sophisticated SPiiPlus EtherCAT based motion control product line, SPiiPlusSPC software…

After making several improvements to the system, scientists restarted the twin detectors of LIGO, the Laser Interferometer Gravitational-wave Observatory. Over the last year, they have made enhancements to LIGO’s lasers, electronics, and optics that have increased the observatory’s sensitivity by 10 to 25%. The detectors, scientists hope, will now be able to tune in to gravitational waves — and the extreme events from which they arise — that emanate from…

Laser emissions created with light and water waves

November 30, 2016

For the first time, Technion researchers have demonstrated that laser emissions can be created through the interaction of light and water waves. This ‘water-wave laser’ could someday be used in tiny sensors that combine light waves, sound and water waves, or as a feature on microfluidic ‘lab-on-a-chip’ devices used to study cell biology and to test new drug therapies. For now, the water-wave laser offers a ‘playground’ for scientists studying…
