摘要

采用新开发的颗粒负载油墨喷涂方法制备了多层透明陶瓷平面波导，并对其进行了表征和激光处理。具有5个Yb:YAG增益区域和4个Lu:YAG折射率匹配区域的波导被制作成“带状激光器”，以及均匀的Yb:YAG波导。元素映射显示，波导厚度从40 μm到69 μm不等，由小于10 μm的层组成。Yb浓度曲线符合扩散曲线。均匀波导和多层波导在激光腔中进行了测试，并产生了相似的斜率效率，最高达到31%。他们的光束轮廓提供了条带结构影响首选模式的证据。

Ink-sprayed transparent ceramic multilayer planar waveguides for ribbon lasers.

Multilayer transparent ceramic planar waveguides were fabricated using a newly developed particle-loaded ink spraying method, characterized, and lased. Waveguides with five Yb:YAG gain regions and four Lu:YAG index-matched regions were produced for application as a "ribbon laser," as well as a homogeneous Yb:YAG waveguide. Elemental mapping revealed that the waveguide thicknesses varied from 40 to 69 μm, comprised of layers of less than 10 µm. The Yb concentration profiles were fit to a diffusion profile. The homogeneous and multilayer waveguides were tested in a laser cavity and produced similar slope efficiencies, with a maximum of 31% achieved. Their beam profiles provided evidence of the ribbon structure affecting the preferred mode.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
