Its imaging system is based on a compact and low-cost pulsed laser illuminator and a light-intensifier equipped CCD camera. By precisely synchronizing both the illuminator and the camera shutter, it ...

Abstract: We report the phase-locking of a quantum cascade laser (QCL) at 10 μm to the secondary frequency standard of this spectral region, a CO2 laser stabilized on a saturated absorption line of ...

The objective of this work was the optical trapping of λ-DNA on a metallic nanostructure with femtosecond-pulsed (fs) laser irradiation. Continuous-wave laser irradiation, which is generally used for ...

It works by firing pulses of laser light (often in the near-infrared spectrum) and measuring the time it takes for them to bounce off objects and return. This helps create precise 3-D maps of the ...
