HighLight SQD from Coherent helps simplify fiber laser process monitoring

The new HighLight® SQD option for Coherent HighLight fiber lasers provides cutting and welding systems integrators with a turnkey means to implement process monitoring.

The option comprises process sensors integrated directly into the company’s fiber laser connectors, which detect back-reflected laser power and visible-spectrum process emissions. These signals, which are provided in either analog or digital CAN bus form (at a 2-kHz sampling rate), can be used to detect various key process events. For cutting, these include piercing end, cut interruption, and self-burning during piercing. For welding, the monitor can indicate incomplete penetration, blow holes, contamination, and gap detection for overlap joints.
