Wide-Wavelength-Range Operation of a Distributed-Feedback Dye Laser with a Plastic Waveguide

Abstract

Results of polarized neutron diffraction on the compound CeB 6 are used to obtain its magnetization density distribution. The measurements are performed at two different points of the magnetic phase diagram (phase I and II). The data are analysed in direct space using the maximum entropy method, as well as in reciprocal space using the cerium form factor expansion and anisotropy. The conclusion is that, in both phases, the magnetization is localized on the cerium sites only. This result is in contradiction to a recent paper by Saitoh et al (2002 J. Phys. Soc. Japan 71 2369), claiming that, in phase II, a localized spin moment was observed at non-atomic sites.

Importance of dye host on absorption, propagation losses, and amplified spontaneous emission for dye-doped polymer thin films

“…Dye-doped polymer thin films have been extensively studied for the past six years as promising gain media. Indeed, they present the advantages of the large spectral range and tuning ability of the dyes 1 and are easily structured into various devices by using different techniques. [2][3][4][5] The materials used for the fabrication of these integrated laser devices fall into three categories: luminescent conjugated polymers, 6,7 dyedoped organic, 8,9 or organomineral solgel 10,11 polymers.…”

Low-Threshold Photopumped Distributed Feedback Plastic Laser Made by Replica Molding

“…[3][4][5][6][7] The second condition, optical feedback, can be accomplished by suitable resonator geometry. [8][9][10][11][12][13][14][15] The most promising method is the use of a periodically structured substrate that provides distributed feedback (DFB) in the lateral direction. This approach can easily be combined with techniques for depositing an organic emissive layer and can be readily used for large-area geometries.…”
