…demonstrated in 1987) is just such a technique6. Here, two intense laser beams (a visible and an
infrared one) are focused on the interface. If the target is non-centrosymmetric, a weak visible
wavelength beam at the sum of the two laser frequencies is generated. When the infrared laser…

…rectangular in
shape with uniform intensity distribution. This beam can
readily be manipulated with beam shaping optics to
match the necessary processing area on the work
piece, and to have a homogeneous intensity
distribution of ~1%, rms over its area.

confocal microscope, but usually in conjunction with optics to homogenize and
spatially filter the light, which increases
complexity and lowers efficiency. Thus,
while multimode lasers with lower-quality beams are often easier to make and so
are usually available at lower…

…precision step-and-repeat processes where the square
beam shape minimizes the process overlap.
When square fibers are combined with our asymmetric
collimating units containing cylindrical lenses the result is
a homogenous rectangular-formed power distribution.

processes to reach these extreme operating domains.

…applied in the case of wafers. Their main difference is the geometry of the homogenized laser field on the substrate. Covering the substrate area for laser lift-off processing occurs either by means of scanning a line beam of an appropriate length or via stitching rectangular laser fields (figure1).…

…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…
