Impact of pre-pulse current and delay time on 46.9 nm laser with... In this Letter, we firstly, to the best of our knowledge, demonstrated the influence of pre-pulse current and delay time on the intensity of a discharge pumped Ne-like Ar soft X-ray laser operating at 46.9 nm by employing an alumina capillary having an ...
Synthetic optical vortex beams from the analogous trajectory cha... We propose a method to generate specially shaped high-order singular beams of pre-designed intensity distributions. Such a method does not

The validity of this propos
Reflection of intense laser light from microstructured targets a... The spatial-intensity profile of light reflected during the interaction of an intense laser pulse with a microstructured target is investigated experimentally and the potential to apply this as a diagnostic of the interaction physics is explored ...

If HR (or heartbeat) can be detected with high accuracy from the optical intensity, this will undoubtedly benefit a lot to many NIRS studies. Previous studies have used the

The quality factor Q and the spontaneous emission coupling ...
Experimental investigation on pulse-contrast degradation caused ... ... obtained by changing the seed-pulse or pump-pulse energy and inserting etalons with different reflection coefficients, respectively. The contrast measurements show that the generated first pre-pulse intensity is proportional to the product of the surfa
Single fiber dual-functionality optical tweezers based on graded... ... the multimode fiber tip to be a special tapered shape, contributing to focus the outgoing beam with a large intensity gradient for the first functionality—three-dimensional contactless trapping of a microparticle. By adjusting the radial direction offset ...
Nonlinear gallium phosphide nanoscale photonics [Invited] We introduce a nanoscale photonic platform based on gallium phosphide. Owing to the favorable material properties, peak power intensity levels of 50 GW/cm2 are safely reached in a suspended membrane. Consequently, the field enhancement is exploited to a ...
