The source emits a laser beam which hits the beam splitter; half of the beam gets sent to the target and then back to the beam splitter; the other half of the beam gets sent to the mirror and then ...

From a telescope network that spans much of the globe to a psychology study that spans 67 countries, here are the biggest ...

The Verifire™ Laser Interferometer provides flatness metrology and surface form of optical components and wavefront of optical systems and subassemblies like windows, lenses, mirrors, prisms—and even ...

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a huge installation measured in kilometers that is listening for wrinkles in space-time. Pulling this off is a true story of ...

For experiments that require ultra-precise measurements and control over atoms — think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates — lasers are the technology of ...

A beam splitter in a Fizeau laser interferometer splits the beam from a laser source ... created short coherence source models for quantifying plane-parallel optics, headed the field with ...

These smaller lasers will enable scalable laser solutions for actual quantum systems, as well as lasers for portable, ...

But if we apply many laser pulses of light to boost the atom interferometer's ability to amplify small signals, those errors will compound. And they will compound fast. In practice, we saw that ...
