DESCRIPTION (provided by applicant): This SBIR Phase I project proposes a novel all-fiber ultra-compact high-power mode-locked fiber laser OPO system based on PolarOnyx's proprietary technologies for polarization and pulse shaping. The proposed laser system is an enabling technology for optical Coherent Anti-Stokes Raman Scattering (CARS) microscopy with two synchronized picosecond (ps) pulses. The design proposed by PolarOnyx employs photonic crystal fibers (PCFs) to manipulate dispersion, Self phase modulation (SPM), and wavelength-dependent gain. The system has no moving parts and requires very little space: the cost and size will be at least four-fold less than other competing approaches. The design is simple yet robust in construction and easy to operate. In the Phase I time frame, a prototype will be built to demonstrate mode locking and high power amplification of ps pulses and conduct a feasibility study for the design of the OPO system. In Phase II, fine tuning of the prototype to achieve high power (>200 mW average power) tunable output pulses will be performed in addition to concurrent evaluation and application of the source to CARS microscopy biophysical imaging and chemical characterization projects.

描述(申请人提供)：该SBIR第一阶段项目提出了一种新颖的全光纤超紧凑型高功率锁模光纤激光器OPO系统，该系统基于PolarOnyx的偏振和脉冲整形专利技术。所提出的激光系统是一种能够实现两个皮秒(PS)脉冲的光学相干反斯托克斯拉曼散射(CARS)显微镜的技术。PolarOnyx提出的设计使用光子晶体光纤(PCF)来操纵色散、自相位调制(SPM)和波长相关增益。该系统没有活动部件，需要的空间很小：成本和尺寸将至少比其他竞争方法少四分之四。该设计简单，但结构坚固，易于操作。在第一阶段的时间框架内，将建立一个原型来演示ps脉冲的锁模和高功率放大，并对OPO系统的设计进行可行性研究。在第二阶段，除了在CARS显微镜生物物理成像和化学表征项目中同时评估和应用信号源之外，还将对原型进行微调，以实现高功率(&gt；200 mW平均功率)可调输出脉冲。
