LIMONCELLO: Laser wrItten millimeter long nanocrystalline lanthanide waveguide lasers with rare earth doping

光子学科学和技术尚未发展，以满足基础科学，激光-物质相互作用，医学和通信等广泛应用中不断的需求。RE 3+掺杂的纳米晶材料最近显示出并入坚固的可加工玻璃的巨大前景。该提案的目标是蒙特利尔理工学院（PM）与拉瓦尔大学合作开发的掺杂RE 3+离子的氟氧化物玻璃，用于高效激光辅助冷却、高功率激光器/放大器系统和其他光学集成电路应用。我们对材料的更好理解和纯化导致了具有纳米晶稀土掺杂的坚固的氟氧化物玻璃的制造，最近我们已经证明了这些玻璃在用激光泵浦时的净加热接近零。这项建议将使我们能够利用飞秒激光写入技术的最低损耗波导的PI，和纳米晶体镧系元素纳入低声子能量玻璃在拉瓦尔大学的紧凑和环境稳健的激光源，需要为现实生活中的应用，往往需要振动不敏感的光学腔，各种便携式，高功率电器。因此，该项目的最终目标是允许使用高纯度，低成本，可模塑的纳米晶体（NC）掺杂稀土掺杂的镧系玻璃的高效率激光泵浦制冷机和低损耗波导的飞秒激光直写（FLDW）技术的制造，用于开发具有成本效益的微型集成电路结合布拉格光栅。

Photonics science and technology has yet to evolve to meet the incessant demands in a wide range of applications such as in basic sciences, laser-matter interaction, medicine, and communications. RE3+-doped nanocrystalline materials have recently shown great promise for incorporation into robust processable glasses. This proposal targets oxyfluoride glasses doped with RE3+ ions at Polytechnique Montreal (PM) in partnership with Laval University, for high efficiency laser assisted cooling, high power laser/amplifier systems and other optical integrated circuit applications. Our better understanding and purification of materials has led to the fabrication of robust oxy-fluoride glasses with nanocrystalline rare earth doping, and recently we have demonnstrated near zero net heating in these glasses when pumped with lasers. This proposal will allow us to exploit the technology of femtosecond laser writing of the lowest loss waveguides pioneered by the PIs, and the nano-crystalline lanthanides incorporated in low phonon energy glass at Laval University for compact and environmentally robust laser sources that are required for real-life applications, often necessitating vibration insensitive optical cavities, for a variety of portable, high power appliances. Hence, the ultimate aims of the proposed project is to allow the use of the highly pure, low-cost, mouldable nano crystalline (NC's)-doped lanthanide glasses with RE3+-doping for high efficiency laser pumped cryo-coolers and the fabrication of low loss waveguides by femtosecond laser direct writing (FLDW) technique, for the development of cost-effective and miniature integrated circuits in combination with Bragg gratings.
