A chip-scale broadband light source in silicon carbide

Optical frequency combs have changed science and technology as we know it. Responsible for measuring things like infrared and ultraviolet light, greenhouse gases, atomic clocks, and disease, optical frequency combs act as ...

The sound of light: Photoacoustics for biomedical applications

Medical imaging techniques provide a unique view inside the body and are invaluable for diagnosis and disease monitoring. From X-ray, over MRI to ultrasound, the field is vast and diverse. When imaging biological tissue, ...

Three-dimensional imaging with optical frequency combs

Holography is a powerful technique of photography of a light field without a lens for 3D imaging and display. Now, scientists at the Max-Planck Institute of Quantum Optics are moving holography forward by implementing it ...

'Agricomb' measures multiple gas emissions from... cows

After the optical frequency comb made its debut as a ruler for light, spinoffs followed, including the astrocomb to measure starlight and a radar-like comb system to detect natural gas leaks. And now, researchers have unveiled ...

Comb of a lifetime: A new method for fluorescence microscopy

Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light within a specific ...

Single laser produces high-power dual comb femtosecond pulses

Researchers have developed a new approach that uses a single laser cavity to create two high-power optical frequency combs emitting high-power femtosecond pulses. The new development paves the way for portable dual-comb light ...

Scientists boost microwave signal stability a hundredfold

Researchers at the National Institute of Standards and Technology (NIST) have used state-of-the-art atomic clocks, advanced light detectors, and a measurement tool called a frequency comb to boost the stability of microwave ...
