Abstract: A monitoring system for a multi-laser module includes detectors corresponding to each laser and situated to receive a portion of the associated laser beam uncombined with other beams. Laser characteristics are measured and stored, and in operation are used to identify device failures. A comparator receives a reference value and compares the reference value with a current operational value. If the current value is less that the reference value, a possible failure is indicated. Signal cross-coupling among the detectors is also used to identify undesirable scattering that can be associated with surface contamination or device failure.
Abstract translation: 用于多激光模块的监视系统包括对应于每个激光器并且被定位成接收未与其它光束组合的相关激光束的一部分的检测器。 激光特性被测量和存储，并且在操作中用于识别设备故障。 比较器接收参考值并将参考值与当前操作值进行比较。 如果当前值小于参考值，则指示可能的故障。 检测器之间的信号交叉耦合也用于识别可能与表面污染或器件故障相关的不期望的散射。
