Femtosecond

Scientists have stored the entire human genome on a five-dimensional crystal capable of storing up to 360 terabytes of information and is built to survive for billions of years. The tech could be used to create an enduring record of human, animal, and plant genomes.

All previous records absolutely pale in comparison to the new record holder for the world’s fastest camera, boasting a mind-boggling rate of 70 trillion frames per second. That’s fast enough to capture light waves in movement.

The world’s fastest camera, developed by researchers at Caltech and INRS, captures the world at a mind-boggling 10 trillion frames per second – fast enough to probe the nanoscale interactions between light and matter.

Laser physicists have captured an atomic-level event – an electron being ejected from a helium atom after being struck by a photon – with an accuracy of a trillionth of a billionth of a second, showing the definitive correlation between quantum theory and experimental proof.

Researchers from Tsukuba University in Japan have created holograms that respond to human touch. Involving femtosecond lasers, which can stimulate physical matter to emit light in 3D form, the research could eventually lead to the creation of holograms that humans are able to interact with.

At 3.2 million watts, the Lawrence Livermore National Laboratory laser diode array is the most powerful ever built, and will form part of an even larger quadrillion watt femtosecond pulsed laser currently under construction for the European Union's Beamline facility in the Czech Republic.

Two collaborating Japanese universities have laid claim to creating the world’s fastest camera. Taking pictures at a resolution of 450 x 450 pixels, it is said to be able take pictures at a mind-boggling 4.4 trillion frames per second.

Gizmag spoke with Raydiance, a company specializing in cutting-edge laser fabrication methods, about its new R-Cut femtosecond laser system that promises a "new paradigm" in high-tech glass fabrication.

A newly-developed laser scalpel is able to precisely remove unwanted diseased or damaged tissue, while leaving adjacent healthy tissue unharmed.

Researchers in MIT’s Media Lab have developed a system using a femtosecond laser that can reproduce low-resolution 3D images of objects that lie outside a camera’s line of sight.

A process for changing the color of metal also results in the metal being able to detect the notoriously difficult to detect terahertz waves, or T-rays, which have potential applications in medical and scientific imaging and security scanning.

Scientists found that femtosecond comb lasers might be the right solution for measuring distances in space to a few microns.
