This is a Small Business Technology Transfer Phase I Project that addresses new materials and manufacturing techniques for fiber lasers. Fiber lasers have emerged as the most energy efficient, diode-pumped, solid-state lasers demonstrated to date. There have been concomitant advances in fiber laser spectral coherence and power scaling. However, less effort has been directed towards developing an integrated manufacturing process for wavelength tuning and spectral coherence control, both of which are crucial to applications such as laser spectroscopy, rugged industrial optical sensors and optical communications. Coherent Technologies, Inc. and Cornell University propose to jointly develop innovative Micro-Opto-Electro-Mechanical Systems (MOEMS) devices to provide these capabilities in fiber lasers. When compared to competing optical technologies, these devices achieve unprecedented wide-band tuning, variable outcoupling, longitudinal mode selection and optical phase control with servo bandwidths 100 kKhz. Stringent wavelength requirements inhibit large scale manufacturing with conventional technology. The MOEMS tuners relieve the issues of process yield.The Phase I theory and proof-of-principle demonstrator will establish technical viability for the Phase II program. The Phase II goal is to build a first-of-kind frequency-agile phase-locked fiber laser oscillator/amplifier that is suitable for commercialization. The devices developed with this technology will operate in hostile environments, as might be encountered in industrial process plants and telecommunications, in programmable wavelength division multiplexing and in reconfigurable optical drop/add switches.

这是一个小型企业技术转让第一阶段项目，旨在解决光纤激光器的新材料和制造技术。 光纤激光器已成为迄今为止最节能的二极管泵浦固态激光器。在光纤激光器的光谱相干性和功率缩放方面也取得了相应的进展。然而，很少有人致力于开发用于波长调谐和光谱相干性控制的集成制造工艺，这两者对于激光光谱学，坚固的工业光学传感器和光通信等应用至关重要。 Coherent Technologies，Inc.和康奈尔大学提议联合开发创新的微光机电系统（MOEMS）设备，以在光纤激光器中提供这些功能。 与竞争光学技术相比，这些器件实现了前所未有的宽带调谐、可变外耦合、纵向模式选择和光学相位控制，伺服带宽为100 kHz。 严格的波长要求抑制了用常规技术的大规模制造。 MOEMS调谐器缓解了工艺良率的问题。第一阶段的理论和原理验证演示器将为第二阶段计划建立技术可行性。 第二阶段的目标是建立一个适合商业化的第一种频率捷变锁相光纤激光振荡器/放大器。 用这种技术开发的设备将在恶劣的环境中工作，如在工业加工厂和电信中可能遇到的，在可编程波分复用和可重新配置的光分插开关中。
