摘要：

Active rare-earth Et3+-Yb3+ co-doped phosphate glass films are produced in a single step by pulsed laser deposition. The films are multimode waveguides and exhibit the highest refractive index, optical density and 1.54 mu m photoluminescence intensity and lifetime when deposited at low oxygen pressure (P-ox less than or equal to 4 x 10(-5) Torr). The density of the films obtained under these conditions is higher than that of the target material as a consequence of the high kinetic energy of the species generated during ablation. Luminescent emission can be excited by optical pumping the Er3+ ions either directly or through cross-relaxation of the Yb3+. Post-deposition annealing allows us to improve the luminescence performance. (C) 1998 American Institute of Physics. [S0021-8979(98)00316-8].
