…system, which also includes
a beam focusing welding head, as well as control electronics. In addition to fiber lasers,
Coherent | Rofin also offers beam delivery components which mount into customers'
machines. These can be fixed optics or complete, integrated scanning solutions,…

…ytterbiumdoped fiber. This fiber-based technology is
optically simpler than Ti:sapphire lasers and
can be economically packaged in a compact
and extremely rugged, zero-maintenance,
sealed laser head. An example of this nextgeneration ultrafast fiber laser is the new…

…also
often need off-the-shelf modular solutions
to enable fiber delivery (both single- and
multimode), plug-and-play combining of
multiple wavelengths, and beam shaping
using refractive and diffractive optics (see
Fig. 3). And in some cases, they require an
engine…

…into the gain fiber using a beam combiner consisting of discrete optical elements. This same beam combiner
collimates the output from the gain fiber, and other optics efficiently couple this into the final delivery fiber.
The geometry of the beam combiner prevents back-reflections…

…plug-and-play combiner, Coherent's OBIS Galaxy, now simplifies this
process. This passive device can integrate
up to eight different laser wavelengths
using a patent-pending combination of a
minimum number of refractive optical
components, together with a novel fiber

…team developed.
Light beams from three Coherent OBIS
FP lasers at 445, 488 and 640 nm are
combined in an OBIS Galaxy plug-andplay beam combiner. The combiner's
single-mode output is then connected to
the single-mode illumination-delivery
fiber in the SFE. At the distal…

guides the beam, it also transforms the spot shape. Square
formed fiber cables are specially aimed for high
precision step-and-repeat processes where the square
beam shape minimizes the process overlap.
