Comparison of Refractive Outcomes Between Small Lenticule Extraction Using a 500 KHz and a 2 MHz Femtosecond Laser [PDF]
DiagnosticsBackground/Objectives: The aim of this study was to compare the efficacy of correcting myopia and myopic astigmatism between small incision lenticule extraction (SMILE) surgery performed using VisuMax 500 and that using VisuMax 800. Methods: Patients who

Gate-tunable negative refraction of mid-infrared polaritons [PDF]
Science, 2022 Negative refraction provides a platform to manipulate mid-infrared and terahertz radiation for molecular sensing and thermal emission applications. However, its implementation based on metamaterials and plasmonic media presents challenges with optical ...

Negative refraction in hyperbolic hetero-bicrystals [PDF]
Science, 2022 We visualized negative refraction of phonon polaritons, which occurs at the interface between two natural crystals. The polaritons—hybrids of infrared photons and lattice vibrations—form collimated rays that display negative refraction when passing ...

Application of Schlieren photography for visualisation of a pulsed gaseous target [PDF]
Biuletyn Wojskowej Akademii Technicznej, 2023 The article describes Schlieren photography, realised using a laser plasma as a radiationsource. Optical systems prepared for visualisation of a stationary gas outflow and a pulsed gaseoustarget, produced in an atmosphere or vacuum environment are ...

Time-refraction optics with single cycle modulation
Nanophotonics, 2023 We present an experimental study of optical time-refraction caused by time-interfaces as short as a single optical cycle. Specifically, we study the propagation of a probe pulse through a sample undergoing a large refractive index change induced by an ...

Refraction Correction for Spectrally Derived Bathymetry Using UAS Imagery
Remote Sensing, 2023 Spectrally derived bathymetry (SDB) algorithms are rapidly gaining in acceptance and widespread use for nearshore bathymetric mapping. In the past, refraction correction could generally be ignored in SDB, due to the relatively small fields of view (FOVs)

Negative refraction makes a perfect lens [PDF]
Physical Review Letters, 2000 With a conventional lens sharpness of the image is always limited by the wavelength of light. An unconventional alternative to a lens, a slab of negative refractive index material, has the power to focus all Fourier components of a 2D image, even those ...
