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 ...

Terahertz zaps alter gene activity in stem cells

Terahertz light pulses change gene expression in stem cells, report researchers from Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) and Tokai University in Japan in the journal Optics Letters. ...

An innovative method to tune lasers toward infrared wavelengths

Researchers at Institut national de la recherche scientifique (INRS) have discovered a cost-effective way to tune the spectrum of a laser to the infrared, a band of great interest for many laser applications. They collaborated ...

Record high values of peak power with picosecond generators

Powerful picosecond generators are in demand in various fields of experimental electrophysics to produce ultrashort electron beams and X-ray pulses in vacuum diodes and to form runaway electron flows in gases.

Custom fabricated microscope lens inspired by lighthouse

An optical device that resembles a miniaturized lighthouse lens can make it easier to peer into Petri dishes and observe molecular-level details of biological processes, including cancer cell growth. Developed by KAUST, the ...
