英文摘要	A diode pumped laser system includes a laser cavity with an active laser medium. A laser diode, with an emitter region having an output facet that produces light at a frequency lambda 1, is the pump source for the laser medium. A coupling optics is positioned on an emission path of radiation from the emitter region and is optically coupled and spaced from the diode. The coupling optics produces stray radiation. An optical fiber, with a first end and a second end, is included. The first end of the fiber is oriented with respect to the coupling optics such that radiation from the emitter region is optically coupled into the optical fiber. The second end of the fiber is coupled to the laser cavity. A detector is positioned in a spaced, adjacent relationship to the coupling optics along an emission path of the stray radiation. The detector detects at least a portion of the stray radiation and produces a detected output in response to the stray radiation. A signal processor is coupled to the detector, and receives the detected output to produce a processed output that is representative of a detected characteristic of the laser system.
