| 英文摘要 | A monitoring apparatus for a high power light source comprises a fiber medium containing a high power output for an application with a first monitoring tap optically coupled to the fiber medium for removing a small portion of light from the output to monitor the output power level. A photodetector is optically coupled to receive the light portion to monitor the output power level. The photodetector, however, has a predetermined saturation level below the power level provided from the first monitoring tap. Therefore, at least one light attenuator is provided between the first monitoring tap and the photodetector to provide a level of monitoring power within a range below the saturation level of the photodetector to accurately monitor changes in the output power present on the fiber medium of the light source. The attenuator may be an optical tap; a beamsplitter, such as a fiber beamsplitter; a WDM splitter; a fused coupler; a bulk optical filter or other micro-optic filter; misaligned, coupled optical fibers; or a fiber bound into a tight loop or coil to provide for optical dispersion loss from the fiber. |
