This Small Business Innovation Research (SBIR) Phase I project aims to develop a novel technique for manufacturing digital planar holograms, which will result in the enhancement of the brightness and power density of high-power laser diodes. Preliminary results of coupling lasers with holograms demonstrated a suppression of lateral modes, which enhances brightness and, additionally, narrows and stabilizes the laser spectrum. The successful introduction of this technology in the laser marketplace depends on the ability to fabricate planar holograms at a low cost and a simplification of their integration with laser diodes. The objective of this project is to develop and launch the commercialization of holographic lasers with higher a brightness and power. Phase I will consist of exploring a novel nano-manufacturing technology for low-cost fabrication of planar holograms by imprinting planar holograms into sol-gel films. The research will explore the issue of correlating the imprint process parameters with the sol-gel material properties to replicate computer-generated holograms with high performance. Phase II will demonstrate the monolithic integration of imprinted planar holograms into commercial laser diodes.The broader impact/commercial potential of this project is that the brightness and power density of current, high-power laser diodes can be increased, while retaining their compact size and low cost. Semiconductor diode lasers have achieved high output power, allowing them to transition from special scientific items into true industrial tools. There is a huge interest worldwide in major industrial applications of semiconductor lasers such as direct materials processing and pump sources for industrial solid-state lasers and optical fiber lasers. Development of laser diodes with higher performance is being pursued by all major laser manufacturers and will have direct applications in multi-billion dollar markets, such as material processing and the semiconductor industry. The proposed nanofabrication process will allow the low-cost fabrication of digital planar holograms and will simplify their future monolithic integration with commercial laser diodes. Competing solutions are much more expensive and less compact.

该小型企业创新研究（SBIR）第一阶段项目旨在开发一种制造数字平面全息图的新技术，这将提高高功率激光二极管的亮度和功率密度。激光与全息图耦合的初步结果表明，横向模式受到抑制，从而增强了亮度，此外，还缩小并稳定了激光光谱。该技术在激光市场的成功引入取决于以低成本制造平面全息图的能力以及其与激光二极管集成的简化。该项目的目标是开发更高亮度和功率的全息激光器并将其商业化。第一阶段将包括探索一种新颖的纳米制造技术，通过将平面全息图压印到溶胶-凝胶薄膜中来低成本制造平面全息图。该研究将探索将压印工艺参数与溶胶凝胶材料特性相关联的问题，以复制高性能的计算机生成全息图。第二阶段将展示压印平面全息图与商用激光二极管的单片集成。该项目更广泛的影响/商业潜力是可以提高当前高功率激光二极管的亮度和功率密度，同时保持其紧凑的尺寸和低成本。半导体二极管激光器已经实现了高输出功率，使其能够从特殊的科学项目转变为真正的工业工具。 全球对半导体激光器的主要工业应用（例如直接材料加工以及工业固态激光器和光纤激光器的泵浦源）有着巨大的兴趣。所有主要激光器制造商都在追求开发更高性能的激光二极管，并将直接应用于材料加工和半导体行业等数十亿美元的市场。所提出的纳米制造工艺将允许数字平面全息图的低成本制造，并将简化其未来与商业激光二极管的单片集成。竞争解决方案更加昂贵且不够紧凑。
