We have demonstrated a high resolution (10 micron) X-ray scintillator plate as part of an indirect X-ray detection system. Scintillator plates are typically integrated with a 2-dimensional array of photodiodes based upon amorphous Si. This paper desc

Radiation Detectors in Medicine, Industry, and National Security XIX.
In digital X-ray imaging, a crucial factor determining image resolution of all indirect detection systems is the spread of light in the X-ray scintillator. Currently deployed clinical x-ray detectors, with a resolution between 75 and 300 microns, are

We numerically model the performance of high-power 977-nm fiber lasers and amplifiers pumped at 915 nm, in which the Yb is doped in a ring inside the core of a high-order-mode (HOM) fiber. Light in the spatially coherent LP07 mode is amplified in the

Minimum infiltration times during isothermal chemical vapor infiltration were calculated for the formation of a silicon carbide matrix composite from methyltrichlorosilane (MTS). Several different reaction models were used to describe the SiC deposit

We report spectral characteristics of amplified spontaneous emission (ASE) from an Er–Tm co-doped silica fiber. When pumped at 980 nm, the ASE yielded a 3 dB bandwidth over 90, 1460–1550 nm. The changes in ASE with regard to temperature, pumping

We demonstrate a single-frequency fiber laser cavity that allows for measuring changes in the relative phase of two independent orthogonal polarization modes. Longitudinal-mode selection is carried out by a matched-pair of fiber Bragg gratings in a F
