A diode-pumped, repetitively Q-switched 1% doped Yb 3+ :Sr 5 (PO 4 ) 3 F laser has been demonstrated for the first time, pumped with a strained InGaAs continuous-wave diode laser. The maximum output energy per pulse was 125 μJ at 1.047 μm, with a p

Lattice vibrations of oriented GdLiF4 and YLiF4 single crystals are studied by polarized Raman spectroscopy. The Raman spectra show identical symmetry properties in both materials implying that the vibrational modes of the new laser crystal GdLiF4 ha

The structures of CaYAlO 4 , CaNdAlO 4 , and SrLaAlO 4 have been refined using single-crystal X-ray diffraction data. These compounds possess the full symmetry of the K 2 NiF 4 structure type, I4 mmm , with lattice parameters a = 3.6451(1) and c = 11

We have studied the electron channeling patterns (ECPs) of both pure a-axis and pure c-axis epitaxial YBa2Cu3O7−δ thin films on various substrates. ECPs from three representative a-axis films [on PrBa2Cu3O7−δ buffered LaAlO3 (001), MgO (001), a

A new class of ordered langasite structure compounds, namely, Sr3NbGa3Si2OI4 (SNGS), Sr3TaGa7Si2OI4 (STGS), Ca3NbGa3Si2OI4 (CNGS) and Ca3TaGa&O14 (CTGS), have been reported [I]. Lower acoustic loss is expected among these compounds. We report our eff

We evaluate the scintillator properties of LYSO (Lu/sub (2-x)/Y/sub x/SiO/sub 5/:Ce) crystals with the amount of lutetium ranging from 15 to 100%. The radii of the cations Lu/sup 3+/ and Y/sup 3+/ differ by only 5%, therefore, one can substitute yttr

This paper discusses the results from two rounds of experimental mapping (with gross and refined incremental cut angle) for BAW device potentials of singly rotated Y-cut plates of the ordered Langasite-structure compounds CNGS, CTGS, SNGS, and STGS.

Summary form only given. Recent publications show high slope efficiencies, high emission cross section, and low laser threshold for Yb/sup 3+/ in appatite host structures. We have developed a Czochralski technique for producing SVAP crystalline boule
