  • Publication number: 20140263971
    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.
