Spatiotemporal self-similar fiber laser
, 2019 In this Letter, we demonstrate, to the best of our knowledge, the first spatiotemporally mode-locked fiber laser with self-similar pulse evolution. The multimode fiber oscillator generates parabolic amplifier similaritons at 1030 nm with 90 mW average ...

Advanced Healthcare Materials, EarlyView.Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

Multimode fiber optic sensors [PDF]
The Journal of the Acoustical Society of America, 1990 A theoretical approach useful in the design of multimode optical fiber sensors is described. An intensity distribution function is derived when assuming that a multimode optical fiber is illuminated by a light source that can be approximated by infinite uniangular beams carrying equal power.
