Resumo: | Modelling of laser oscillation at 0.9 µm in Ti waveguides in LiNb03 doped with Nd ions is presented. Laser emission at 0.9 µmin Ti waveguides in Nd:LiNb03 crystals was recently demonstrated. However, lasing was reported as unstable and lasting only a few seconds, with parasitic lasing at the higher gain transition at 1.08 µm shown to be a problem. In this work the possibility of obtaining efficient and stable laser oscillation at 0.9 µmin Ti:LiNb03 waveguides, fabricated in substrates doped with Nd ions by thermal diffusion of thin metallic stripes or planar thin films, was theoretically evaluated. It was concluded that emission at 0.9 µm, with complete suppression of the parasitic emission at 1.08 µm, should be possible by selective increase of the losses at 1.08 µm, through optimization of waveguide and laser cavity, spatial localization of the Nd ions and the use of the dependence on polarization of the emission cross sections at 0.9 and l.08µm. |
