This Small Business Innovation Research (SBIR) Phase I Project proposes to develop a novel, monolithic external-cavity to tune near-UV laser diodes now commercially available between 375 and 440 nm. The external cavity will provide electro-optic control over both the lasing wavelength and the cavity optical path enabling single-mode, mode-hop-free tuning over 5-10 nm sections. The entire optical package will be centimeter sized, environmentally robust, and deliver 2-10 mW of optical power. Tuning speeds are proposed to be in millisecond time scales. Tunable blue and visible laser diodes with these tuning characteristics would be useful for spectroscopy-based sensors of many light molecules, elements, and biogenic materials.Tunable diode lasers from the violet to the IR would have broader impacts to scientific education, the research community, and to the economy. Educators should welcome low-cost alternatives to dye lasers allowing sophisticated atomic and molecular spectroscopy experiments to be performed with modest budgets. Researchers should be able to use a wider variety of wavelengths in their experiments. Tunable blue and visible laser diodes would find early commercial success in the scientific research markets where they would replace troublesome dye-laser systems and expensive frequency-doubled Ti-Sapphire lasers. The robust and compact form factor of our laser, combined with decisive control over the output wavelength should enable a wide variety of in-situ spectroscopy-based sensors for hand-held devices, engine exhaust sensors, and combustion monitoring,

该小型企业创新研究 (SBIR) 第一阶段项目建议开发一种新颖的单片外腔，以调谐现已商用的近紫外激光二极管，波长范围为 375 至 440 nm。外腔将对激光波长和腔光路提供电光控制，从而实现 5-10 nm 部分的单模、无跳模调谐。整个光学封装尺寸为厘米，具有环保性能，可提供 2-10 mW 的光功率。建议调谐速度以毫秒为单位。具有这些调谐特性的可调谐蓝色和可见激光二极管将可用于许多光分子、元素和生物材料的基于光谱的传感器。从紫光到红外的可调谐二极管激光器将对科学教育、研究界、和经济。教育工作者应该欢迎染料激光器的低成本替代品，允许以适度的预算进行复杂的原子和分子光谱实验。研究人员应该能够在实验中使用更广泛的波长。可调谐蓝色和可见激光二极管将在科学研究市场取得早期商业成功，取代麻烦的染料激光系统和昂贵的倍频钛蓝宝石激光器。我们的激光器坚固而紧凑的外形尺寸，加上对输出波长的决定性控制，应该能够实现各种基于原位光谱的传感器，用于手持设备、发动机排气传感器和燃烧监测，
