Potassium titanyl phoshate (KTP) crystal has superior nonlinear properties as well as excellent electro-optic characteristics. In this paper, a single KTP crystal used as both intracavity voltage-increased electro-optic Q-switch and optical parametric generator simultaneously is researched theoretically. The external applied voltage and optimum type-II phase matching angles for KTP crystal is theoretically...
Picosecond x-ray diffraction using a quasi-collimating polycapillary optic and a laser plasma based x-ray source is demonstrated, significantly reducing data acquisition time for time-resolved studies.
In this paper, XLPE laminate was employed as test sample to investigate the effect of cross-linking temperature on characteristics of electrical treeing. The samples were cross-linked at the temperature ranged from 150°C to 220°C by adding dicumyl peroxide (DCP) as cross-linking agent into low density polyethylene (LDPE). A pair of needle-plate electrodes was employed to initiate the tree by applying...
Er3+-doped fluoride glass ceramics planar waveguides containing LaF3 or binary LaF3-ZrF4 nanocrystals have been fabricated by Physical Vapor Deposition (PVD). A quantitative analysis of the photoluminescence of the 1.54 µm emission band of Er3+ ions has demonstrated that erbium ions are partitioned in both crystals and vitreous phase. The solubility of Er3+ in the segregated LaF3 nanocrystals can...
