In a study published today in the journal Nature Communications, Australian […]

Concept for Exawatt-class lasers. Credit: Osaka University Researchers from Osaka University propose a concept for next-generation ultra-intense lasers, possibly increasing the current record from 10 Petawatts to 500 Petawatts. Ultra-intense lasers with ultra-short pulses and ultra-high energies are powerful tools for exploring unknowns in physics, cosmology, material science, etc. With […]

The LDG/MIP-based electrochemical sensor sensitively and selectively detects BPA in water samples. Credit: © 2020 KAUST A simple method developed at KAUST uses laser beams to create grapheneelectrodes that have better performance than those produced through older methods. Electrodes consisting of graphene, an atypical form of carbon, may transform the way […]

Original artwork by Ludmila Odintsova Lasers were created 60 years ago this year, when three different laser devices were unveiled by independent laboratories in the United States. A few years later, one of these inventors called the unusual light sources “a solution seeking a problem”. Today, the laser has been […]

Electrically pumped surface plasmon-polariton nanolaser. Credit: Dmitry Fedyanin Researchers from the Moscow Institute of Physics and Technology and King’s College London cleared the obstacle that had prevented the creation of electrically driven nanolasers for integrated circuits. The approach, reported in a recent paper in Nanophotonics, enables coherent light source design on […]

A new study in Nature Photonics details the unique properties of the UCF-developed laser beam. The speed of a message traveling in these packets is no longer affected by traveling through different materials of different densities. University of Central Florida researchers have developed a new type of laser beam that […]

Electrons in the crystal of calcium fluoride; Christian HackenbergerElectrons in the Crystal of Calcium Fluoride. Credit: University of Rostock The researchers used powerful laser flashes to irradiate thin, films of crystalline materials. These laser pulses drove crystal electrons into a fast wiggling motion. As the electrons bounced off with the […]

An MIT-designed miniature “squeezer” reduces quantum noise in lasers at room temperature. The marble-sized system could enable better laser precision for quantum computing and gravitational-wave detection. This illustration shows an artist’s interpretation of the system.

New ground-breaking research from the University of Surrey could change the way scientists understand and describe lasers – establishing a new relationship between classical and quantum physics. In a comprehensive study published by the journal Progress in Quantum Electronics, a researcher from Surrey, in partnership with a colleague from Karlsruhe Institute […]
