Cornell engineers have created a deep-ultraviolet laser using semiconductor materials that show great promise for improving the use of ultraviolet light for sterilizing medical tools, purifying water,...
Characterization of Automotive Paint Clear Coats by Ultraviolet Absorption Microspectrophotometry with Subsequent Chemometric Analysis
forensics automative paint clear coats microspectrophotometry
2015/1/7
Clear coats have been a staple in automobile paints for almost thirty years and are of forensic interest when comparing transferred and native paints. However, the ultraviolet (UV) absorbers in these ...
Fabrication of Microfiber-Based Bragg Gratings with Ultraviolet-Light Exposure
Fiber Bragg gratings Integrated optics devices Microstructure fabrication
2015/5/22
We fabricated microfiber-based Bragg gratings with ultraviolet-light exposure. Bragg reflections are observed for gratings with diameters of several micron-meters. The dependence of Bragg grating char...
Fabrication of First-Order Periodically Poled MgO: LiNbO3 Bulks for Ultraviolet Light Generation
QPM SHG Domain inversion
2009/6/8
We propose a novel method for controlling the shape of a short period domain-inverted structure utilizing a multi-pulse poling method. Using this technique, periodically domain-inverted structures wit...
Progress on All Solid State Deep-ultraviolet Laser with KBe2BO3F2 Crystal
DUV KBBF Solid state laser
2009/6/1
General review for the progress on all solid state deep ultraviolet (DUV) laser with a KBe2BO3F2 (KBBF) crystal was given in the paper. The frequency-conversion characteristics of KBBF crystal and the...
Ultraviolet photoconductive detector with high visible rejection and fast photoresponse based on ZnO thin film
ZnO MSM Photoconductive detector Responsivity
2011/12/8
In this study, metal–semiconductor–metal (MSM) photoconductive detector was fabricated on c-axis preferred oriented ZnO film prepared on quartz by radio frequency magnetron sputtering. With the applie...
