Staged acceleration, driven by terahertz (THz) frequency radiation pulses in a lattice with alternating orientation dielectric-lined waveguides and intervening matching optics, is shown to mitigate transverse emittance and energy spread growth, openi

Periodically-poled lithium niobate (PPLN) sources consisting of custom-built stacks of large-area wafers provide a unique opportunity to systematically study the multi-cycle terahertz (THz) generation mechanism as they are assembled layer-by-layer. H

The inclusion of NaF or LiF into rare-earth (R 3+ ) doped CaF 2 and SrF 2 increases the concentration of isolated R 3+ ions to the point where these cubic symmetry centers dominate the defect site distribution. The optical spectra of these centers ar

Ruby, with a high concentration of chromium ions, emits sharp line emission from single ions and from exchange-coupled ion pairs. Large variations in the intensities and lifetimes of these sharp lines are observed, when the temperature is varied (X.X

The temperature dependence of fluorescence depolarization has been investigated in C4v(F−) centers in Pr3+ and Eu3+ doped CaF2 and SrF2 crystals. A single potential barrier for the reorientation of the interstitial fluorine was sufficient for the E

Site-selective laser spectroscopy, Zeeman infrared, and optical absorption have been employed to investigate trivalent dysprosium centers in rare-earth-doped alkaline-earth fluoride crystals. These studies have characterized the two dominant centers
