a b s t r a c tMonoclinic 2 at% Eu-doped KY(WO 4 ) 2 is grown by top-seeded solution growth method. Polarizationresolved absorption and stimulated-emission cross-section spectra are determined for this crystal. Spectroscopic properties of Eu:KY(WO 4 ) 2 are modeled within conventional Judd-Ofelt theory, as well as theory of f-f transition intensities for systems with anomalously strong configuration interaction, yielding absorption oscillator strengths, luminescence branching ratios and radiative lifetime of 5 D 0 state. The impact of excited-state absorption from this state on possibility of laser operation is discussed. Photoluminescent properties of Eu:KY(WO 4 ) 2 are determined. This crystal provides intense red emission with CIE coordinates x¼0.670, y¼0.329.

“…3 shows the polarized effective stimulated emission cross section of the same sample for the F -I and F -I transitions. This was calculated from the fluorescence spectra , using the relation [24], [25] (1) where refractive index; radiative lifetime of the upper manifold, F ; (superscript) polarization (TE) or (TM). The values used for the branching ratios are given in Table III and the radiative lifetime was taken to be 550 s. The calculated emission cross section for the 1.06-m band shown in Fig.…”

Abstract-We report the first fabrication and laser operation of channel waveguides based on LaF 3 planar thin films grown by molecular beam epitaxy. To our knowledge, this is the lowest phonon energy dielectric material to have shown guided-wave laser operation to date. A full characterization, in terms of spectroscopy, laser results, and propagation losses, is given for the planar thin films upon which the channel waveguides are based. Two channel-fabrication methods are then described, the first involves ion milling and the second takes the novel approach of using a photo-definable polymer overlay. Laser operation in Nd-doped samples is demonstrated at 1.06, 1.05, and 1.3 m, and the potential for mid-infrared laser sources based on such guides is discussed.

“…The other method for obtaining stimulated emission cross-section spectra is due to Fuchtbauer and Ladenburg, which obtains its result from measured fluorescence spectra. The derivation is given nicely in Aull and Jenssen (14), with the resulting equation given here after removing an extraneous factor from their equation:…”
