The two spectra show different composition dependence, which can be accounted for by taking related electronic wave functions and the densities-of-states into account. This interpretation can be extended to understand high optical nonlinearity in heavy-metal oxide glasses.American Institute of PhysicsJournal Articleapplication/pdfhttp://hdl.handle.net/2115/5726https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5726/1/APL83-15.pdf0003-6951Applied Physics Letters8315301230142003-10-13enginfo:doi/10.1063/1.1618929Copyright © 2003 American Institute of Physicspublisher
