摘要： An enclosure for a cavity enhanced optical spectroscopy instrument provides a highly temperature stable environment by positioning the instrument optical cavity away from the enclosure walls and providing a wall mounted heat pump, fan and heat exchanger. The fan causes the gas contained within the enclosure to circulate over the heat exchanger and in a laminar, non-turbulent flow path along interior wall surfaces of the enclosure thereby maintaining the optical cavity in a temperature and vibration stable zone.

摘要： A fiber optic gain system has output power monitoring and control using the detected level of side light emitted through the cladding of the gain fiber. The fiber is wound on a spool that is provided with an opening adjacent to the fiber cladding. A photodetector is mounted to the spool at an opposite side of the opening, and detects side light that is transmitted through the opening. An output signal from the photodetector is indicative of the output power or the gain of the system, and may be used for monitoring and/or to adjust the power generated by a pumping source for the system. This allows feedback control of the system that helps to stabilize the output power or gain. A filtering element may also be used to exclude certain undesired wavelengths from the side light being detected.
摘要翻译：光纤增益系统使用通过增益光纤的包层发射的侧光的检测电平来进行输出功率监测和控制。纤维缠绕在带有邻近纤维包层的开口的线轴上。光电检测器在开口的相对侧安装到卷轴上，并检测透过开口的侧光。来自光电检测器的输出信号表示系统的输出功率或增益，并且可以用于监测和/或调整由系统的泵浦源产生的功率。这允许系统的反馈控制有助于稳定输出功率或增益。滤波元件也可用于从被检测的侧面光中排除某些不需要的波长。
