New nanomechanical oscillators with record-low loss

The vibrational modes of nanomechanical resonators are analogous to different notes of a guitar string and have similar properties such as frequency (pitch) and lifetime. The lifetime is characterized by the quality factor, ...

Research produces intense light beams with quantum correlations

The properties of quantum states of light are already leveraged by such highly sophisticated leading-edge technologies as those of the latest sensitivity upgrades to LIGO, the Laser Interferometer Gravitational-Wave Observatory, ...

Laser prototype for space-based gravitational wave detector

Researchers have announced a prototype for a laser at the heart of the first space-based gravitational wave observatory, known as the Laser Interferometer Space Antenna (LISA) mission. The team's new laser nearly meets the ...

The economic impact of a Very Large Telescope

The European Southern Observatory's VLT, Very Large Telescope, is a group of four 8.2-metre diameter optical telescopes located in northern Chile. It also has four movable 1.8-metre diameter auxiliary telescopes and they ...

Very Large Telescope celebrates 15 years of success

(Phys.org) —With this new view of a spectacular stellar nursery ESO is celebrating 15 years of the Very Large Telescope—the world's most advanced optical instrument. This picture reveals thick clumps of dust silhouetted ...

Scaling up breakthrough optical fibre micro sensors for market

Scientist Davide Iannuzzi and his team have developed a method to place novel miniaturised mechanical devices on the tips of optical fibres. The technology has many applications, such as providing a new generation of small, ...
