A lot of what I write is about measurement, not because I'm in love with calipers, but because the cutting edge of physics is at the limit of what we can measure. That means that when you want to ...

Certain detection of gravitational waves requires at least two detectors located at widely separated sites. Regional phenomena such as micro-earthquakes, acoustic noise, and laser fluctuations can ...

This article outlines how to measure, control, and stabilize the relative distance of two interferometer paths to sub-wavelength precision over numerous wavelengths, using the Zurich Instruments MFLI ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

The following application note describes how to use the Zurich Instruments MFLI, a 500 kHz Lock-in Amplifier, for the purpose of measuring, stabilizing, and controlling the relative distance of two ...

Inconceivable, but true: if you want to detect gravitational waves one day using an installation such as GEO600, you must measure the mutual shift of two light waves by a hundred billionth of a degree ...

A significant advance in our understanding of the early evolution of the universe has been achieved by a team of scientists associated with the Laser Interferometer Gravitational-Wave Observatory ...

The resolution of an interferometer is dependent on the linewidth of the illuminating laser, wavelength stability and its absolute wavelength. UniKLasers introduce a range of single frequency lasers ...

The event was momentous—and the statement announcing it to the world came in a duly excited tone, while also being spare and to the point: “Ladies and gentlemen, we…have detected…gravitational waves!

UniKLasers have recently launched second-generation Solo 640 Series of lasers, which deliver impressive output power of 1000 mW. The new series now include customer-focused specification enhancements: ...
