JK Lasers Release Mode Converter Fiber Coupler

Date Announced: 17 Feb 2011

MCFC designed to provide increased Flexibility for Processing with JK Fiber Lasers

The recently released Mode Converter Fiber Coupler (MCFC) has been developed to provide further flexibility to users of JK Fiber Laser products.

The MCFC takes a Gaussian profile single mode fiber input from any of the JK Fiber Lasers and couples it into a JK Luminator fiber, allowing for the use of the full range of JK Fiber Lasers with established and industrially proven JK Luminator process tools.

The output from the JK Luminator fiber has a uniform ‘flat-top’ beam profile and a beam diameter of 150-600µm depending on the configuration selected by the user. Focused spot sizes in the range of 60-1500µm can be selected by use of the appropriate JK Luminator™ process tools.

Use of the MCFC can bring real processing advantages to welding applications where the profile and small spot size of the Gaussian beam are not optimal, such as butt welding parts with fit-up tolerances larger than the Gaussian spot size or thin foil welding, where high intensity on-axis can lead to burn through in the weld centres.

Having a detachable output fiber, with JK Lasers’ Plug-In Pre-Aligned (PIPA) technology for rapid changeovers, allows the MCFC to offer increased versatility to the user from their JK Fiber Laser, at a fraction of the cost of a separate laser.
