研制了1486 nm泵浦的x切同成分铌酸锂（LiNbO_3）掺铒钛扩散脊波导光放大器和激光器。在4.6cm长的波导中，当耦合泵浦功率为200 mW时，获得了14 dB的总增益。我们证明了激光器工作在1561 nm的斜率效率为33%，超过最佳文献值的Er：Ti：LiNbO 3波导激光器。为了提高放大器/激光器的性能，我们的三面Er和Ti内扩散到预定义的脊的新的制造技术被使用。(C)2017美国光学学会
Highly efficient erbium-doped titanium in-diffused ridge waveguide optical amplifiers and lasers in x-cut congruent LiNbO3 pumped at 1486 nm have been developed. A total internal gain of 14 dB has been achieved in 4.6 cm-long waveguides for a coupled pump power of 200 mW. We demonstrated a laser operating at 1561 nm with a slope efficiency of 33% exceeding the best literature values for Er:Ti:LiNbO3 waveguide lasers. To improve the amplifier/laser performance, our novel fabrication technique of three-side Er and Ti in-diffusion into pre-defined ridges was used. (C) 2017 Optical Society of America
