STTR PHASE I: Diode-Pumpable Compact Blue Fiber Lasers for Optical Data Storage and Printing Applications

* 9632263谢 STTR第一阶段项目描述了两种新颖的二极管泵浦、紧凑、高效的蓝色激光源设计。 在包括高密度光数据存储、激光打印和自由空间光通信的许多应用中需要这样的源。 目前，对于这些应用，这种紧凑且有效的源在商业上不可得。在这个建议中描述的设计是基于稀土掺杂氟锆酸盐（ZBLAN）玻璃光纤中的上转换激光。 第一种是Pr/Yb共掺杂光纤，其先前已被证明为在红色、橙子、绿色和蓝色波长下工作的激光器。然而，蓝色激光器的输出功率受到严重限制，这是由于来自共同的上激光能级的竞争跃迁。我们的解决方案的问题进行了描述，并将在本提案中进行测试和开发。第二个上转换蓝光光纤激光器是基于掺Tm的ZBLAN光纤。这种激光器也已经被证明，但缺乏一个方便的，可扩展的，基于二极管的泵浦源的商业化。在这个项目中，一个新颖的和有效的泵浦源将被开发和演示。将为上述两种设计中的每一种设计建造原型激光系统，并对它们进行测试，以备将来发展之需 潜在的应用是在光学数据存储、打印应用、自由空间光通信、光学显示、光谱学、流式细胞术、分子生物学、高性能成像和半导体检测领域。 ***

*** 9632263 Xie This STTR Phase I propject describes two novel designs for diode-pumped, compact, efficient, blue laser sources. Such sources are needed in many applications including high density optical data storage, laser printing, and free space optical communication. Presently, such compact and efficient sources are not commercially available for these applications. The designs described in this proposal are based on upconversion lasing in rare-earth doped fluorozirconate (ZBLAN) glass fiber. The first is a Pr/Yb co-doped fiber which has previously been demonstrated as a laser operating at red, orange, green and blue wavelengths. The blue laser output power, however, was severely limited due to competing transitions from a common upper laser level. Our solution to the problem is described and will be tested and developed in this proposal. The second upconversion blue fiber laser to be developed in this proposal is based on Tm doped ZBLAN fiber. This laser has also been demonstrated, but lacks a convenient, scalable, diode-based pump source for commercialization. In this project, a novel and efficient pump source will be developed and demonstrated. Prototype laser systems for each of the two designs mentioned will be constructed and tested for future development Potential applications are in the fields of optical data storage, printing applications, free space optical communications, optical display, spectroscopy, flow cytometry, molecular biology, high performance imaging, and semiconductor inspection. ***
