Fiber Coupler

photonics | Posted: 17 Jul 2017, 10:16

The Fiber to Fiber Coupler from Coherent Inc. enables the use of replaceable, process fiber optic cables to protect the fiber laser’s integral components from optomechanical damage. 
Fiber Coupler
 
The device enables the use of a separate fiber interface to prevent exposure of integral components from optomechanical damage in industrial applications. This separate delivery fiber can be exchanged in minutes in the case of damage. The coupler is an eye-safe, standalone, water-cooled photonic component that handles laser power levels of 12 kW. A range of options enables coupling between fibers of different core diameters as well as QB, QD and Q5 commonly used connector interfaces. 
 
The coupler incorporates DGUV-certified safety electronics and is an extension of the feeding fiber interlock circuit. It also includes integrated sensors, monitored and controlled by CANopen communication, whose threshold values can be set to enable or disable the interlock circuitry. The coupler is ideal for high-power industrial applications of fiber lasers.
