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 ...

Researchers use infrared light to detect molecules

Ordinary solid-state lasers, as used in laser pointers, generate light in the visible range. For many applications, however, such as the detection of molecules, radiation in the mid-infrared range is needed. Such infrared ...

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 ...

Silicon core fishbone waveguide extends frequency comb

Frequency combs are becoming one of the great enabling technologies of the 21st century. High-precision atomic clocks, and high-precision spectroscopy are just two technologies that have benefited from the development of ...

Researchers achieve broadest microcomb spectral span on record

Xu Yi, assistant professor of electrical and computer engineering at the University of Virginia, collaborated with Yun-Feng Xiao's group from Peking University and researchers at Caltech to achieve the broadest recorded spectral ...
