…lasers is limited. One way to boost brightness is through improved fiber coupling. Achieving this involves shaping of the diode laser beam, as well as multiplexing several beams, to fit the fiber geometry and numerical aperture. There are other changes that can be done to the laser itself.…

parameters, like the intensity, and it
further does not enable you to control the
pulse energy (without an external modulator)," Kahmann said.

…pulse overlap to completely avoid any
damage to the underlying silicon. Figure 3 (right)
shows an example of this using a beam with
a uniform profile shaped using a top hat optic.
The closely spaced square holes in the (<100
nm thickness) SiN shown here confirm that the…

…dimension. Optics reshape the beam in
the NORIA system such that it can write
FBGs from 1 to 10 mm in length. The capability for beam apodization is directly
built into the NORIA system. This is accomplished by using a shaped aperture
in the beam path to convert the uniform

…is first
created by a mechanical or laser process and
then propagated by moving the CO laser beam
in the desired shape. This creates a through cut
in the glass. Free-form shapes can be cut in
glass thicknesses of up to 300 µm, and straight
line cuts can be made in up to…

…ages. · ULN does not change the spatial qualities of the laser beam, so the beam can be focused to the same spot size, profile and shape. FEATURES · Ultra-low noise (ULN) · RMS noise <0.06% for bandwidths of 10 Hz to 10 MHz · Circular beam · No mode-hop noise · No warm-up period · Wavelength 635 nm…

…the next generation of glass panels.
It's important to note that the multiple beams are not simply
stitched end-to-end to produce the final line. Rather, the beams
are combined first, and then shaped to their final line profile.
This beam-combining approach was taken because, in…
