HighLight FL
High-Power Multi-Mode Fiber Lasers with
Beam Management
The HighLight
TM
FL series of industrial, multi-kilowatt ber lasers
provides a cost-eective solution for many common welding tasks.
These lasers feature Coherent’s unique multi-stage back reection
immunity system which enhances reliability and lifetime, and enables
safe processing of highly reective materials, including brass, copper,
and aluminum.
To maximize operational exibility, HighLight FL products are equipped
with either a Fiber-Fiber-Switch (FFS) or Fiber-Fiber-Coupler (FFC).
The FFS enables rapid switching of laser output between up to four
separate process bers, thus allowing time or energy sharing amongst
four workstations with a single laser. The FFC allows easy exchange of
process bers on site.
