The CW-MHF Mid-IR Laser is ideal for high-resolution mid-IR spectroscopy. If users require excellent spectral resolution, phase-continuous tuning to avoid hopping across spectral lines, or both, the ...

Free-electron laser (FEL) sources can generate tunable short-wavelength coherent pulses that can be used for studying structure and dynamics of matter in different forms. In this open collection, we ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.220002 considers femtosecond laser induced periodic surface structures. The laser induced periodic surface structures (LIPSS) is a ...

Scientists show that it is possible to make a femtosecond laser that fits in the palm of one's hand using a glass substrate. Is it possible to make a femtosecond laser entirely out of glass? That's ...

Femtosecond lasers are turning nanostructures into a new kind of thermal hardware, where heat can be sculpted almost as precisely as light. By carving periodic patterns and buried modifications into ...

Physicists routinely exploit femtosecond light pulses to track the movement of atoms in molecules, and are now developing sources that emit even shorter bursts of X-rays to study and control the ...

A project at Swiss research center EPFL has manufactured a palm-sized all-glass GHz femtosecond laser cavity, potentially offering a novel route to free-space femtosecond lasers. Conventional ...

Ultrafast laser processing creates silicon surfaces that absorb nearly all infrared light and remain stable under heat and wear, enabling coating-free infrared sensing and calibration. (Nanowerk ...

The interactions in photovoltaic materials that convert light into electricity happens in femtoseconds. How fast is that? One femtosecond is a quadrillionth of a second­­. To put that in perspective, ...
