在这项工作中,我们报告了有效的掺钕钛扩散脊波导激光器在x切一致的铌酸锂在814 nm的激发下。对于样品制造,我们使用了我们的三面蒸发和内扩散的新技术,将Nd和Ti掺入到预定义的脊中。由于提高了抗光折变损伤的氧化铟锡(ITO)涂层,我们实现了稳定的激光器在1084.7 nm的最大输出功率为108 mW和34%的斜率效率超过最佳文献值的Nd:Ti:LiNbO3脊波导激光器。
In this work, we report on efficient neodymium-doped titanium in-diffused ridge waveguide lasers in x-cut congruent LiNbO3 under excitation at 814 nm. For the sample fabrication we used our novel technique of three-side evaporation and in-diffusion for Nd and Ti incorporation into pre-defined ridges. Due to improved photorefractive damage resistance by indium tin oxide (ITO) coating we achieved stable laser operation at 1084.7 nm with a maximum output power of 108 mW and a slope efficiency of 34% exceeding the best literature values for Nd:Ti:LiNbO3 ridge waveguide lasers.
