High-power laser light communication apparatus
A recently granted patent (Publication Number: US11921335B2) discloses an apparatus designed to facilitate the communication of high-power laser light for laser processing operations within a high-power laser system. The apparatus includes a cable with a power fiber for transporting the laser light, along with first and second monitoring channels for conducting monitoring signals. An evaluation unit is integrated to redundantly monitor the transport of laser light by analyzing the monitoring signals, which also carry user data associated with the laser system. This innovative system allows for the simultaneous monitoring of laser light transport and transmission of user data through the same channels, enhancing efficiency and safety in laser processing operations.
Furthermore, the patent details various configurations and functionalities of the apparatus, such as the transmission of user data signals through electrical, optical, or electromagnetic means, the generation of user data within the cable or external components, and the exchange of user data between subsystems of the laser system. The evaluation unit is equipped to handle control data, sensor data, and other types of user data, ensuring seamless communication between different parts of the high-power laser system. Additionally, the apparatus includes safety features to detect interruptions in laser light transport, such as plug-in interrupts or breakage damage, with the ability to shut down the system in response to such incidents. Overall, this patented technology offers a comprehensive solution for monitoring and transmitting data in high-power laser systems, contributing to improved performance and operational reliability in laser processing applications.
