摘要	A system for widely spaced wavelength tunable diode laser absorption spectroscopy includes at least a first and second tunable diode laser generating laser light at a first and second wavelength, wherein laser light of the first and second wavelengths cannot co-propagate efficiently on the same single-mode fiber. A first fiber may be configured to carry light in the first wavelength, and a second fiber configured to carry light in the second wavelength. A fiber bundle may be formed from the distal ends of the first and second fibers stripped of their respective coatings, and arranged with their claddings adjacent to each other. One or more pitch heads are configured to project respective beams of laser light from the fiber bundle through a measurement zone. One or more catch heads located across the measurement zone receive the respective beams and direct the respective beams onto at least one sensor.
其他摘要	用于宽间隔波长可调谐二极管激光吸收光谱的系统包括至少第一和第二可调谐二极管激光器，其产生第一和第二波长的激光，其中第一和第二波长的激光不能在同一单一波长上有效地共同传播。模式光纤。第一光纤可以被配置为承载第一波长的光，第二光纤被配置为承载第二波长的光。纤维束可以由剥离它们各自涂层的第一和第二纤维的远端形成，并且布置成使它们的包层彼此相邻。一个或多个俯仰头配置成将来自光纤束的相应激光束投射通过测量区。位于测量区域两侧的一个或多个捕获头接收相应的梁并将相应的梁引导到至少一个传感器上。
