*** 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. ***

*** 9632263 Xie 该 STTR 第一阶段项目描述了二极管泵浦、紧凑、高效、蓝色激光源的两种新颖设计。 许多应用都需要这种光源，包括高密度光学数据存储、激光打印和自由空间光通信。 目前，这种紧凑且高效的来源在商业上还无法用于这些应用。该提案中描述的设计基于稀土掺杂氟锆酸盐（ZBLAN）玻璃纤维中的上转换激光。 第一种是 Pr/Yb 共掺杂光纤，此前已被证明可作为在红色、橙色、绿色和蓝色波长下工作的激光器。然而，由于来自公共较高激光能级的竞争跃迁，蓝色激光输出功率受到严重限制。我们对该问题的解决方案进行了描述，并将在本提案中进行测试和开发。本提案中要开发的第二个上转换蓝色光纤激光器基于掺铥 ZBLAN 光纤。这种激光器也已得到演示，但缺乏用于商业化的方便、可扩展、基于二极管的泵浦源。在该项目中，将开发并演示一种新颖高效的泵源。上述两种设计的原型激光系统都将被构建和测试，以供未来开发。潜在的应用包括光学数据存储、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查等领域。 ***
