Near-field holography(NFH), with its virtues of precise critical dimensions and high throughput, has a great potential for the realization of soft x-ray diffraction gratings. We show that NFH with reflections reduce...

The combination of deep wet etching and a magneto-rheological finishing (MRF) process is investigated to simultaneously improve laser damage resistance of a fused-silica surface at 355 nm. The subsequently deposited...
A model is developed to improve thickness uniformity of coatings on spherical substrates rapidly and au- tomatically using fixed shadow masks in a planetary rotation system. The coating thickness is accurately represe...
For high precise laser systems like laser gyro, gravitational waves interferometers, the optical components which lie in the cavity or laser path need to control the total loss, scattering, reflection, absorption, and...
The infrared emissivity of low emissivity coating can be significantly reduced by adding high content concentrations of parallel distributed metallic flake pigment. However, the infrared emissivity is very difficult t...
We discuss a merit function F as judgment of photo-thermal conversion efficiency instead of two indepen- dent parameters: solar absorptance α and thermal emittance ε. The merit function F is developed using Essenti...
Optical microfibers (OMs) are good alternatives in the field of sensing. In this letter, a simple and effective miniature temperature sensor based on OM is proposed and experimentally verified. Using pure water and ...

A simplified modal method to explain the resonance phenomenon in guided mode resonance (GMR) grat- ings with asymmetric coatings is presented. The resonance observed is due to the interaction of two propagation mode...
The accumulation effects in high-reflectivity (HR) HfO2/SiO2 coatings under laser irradiation are investigated. The HR HfO2/SiO2 coatings are prepared by electron beam evaporation at 1 064 nm. The laser-induced dama...
A camera-based model is established to predict the total difference for samples of metallic panels with effect coatings under directional illumination, and the testing results indicate that the model can precisely pre...
