…cylindrical
lens arrays expand and homogenize the
beam for uniform illumination of the
mask at the desired laser fluence.
Using a Schwarzschild objective with
25× magnification, the illuminated
mask is imaged onto the sample located
on precision stages. The whole system is…

…demagnifying an UV excimer laserâs beam interference pattern as it is formed after passing a phase mask by means of appropriate high-resolution Schwarzschild projection optics onto the desired sample. As in excimer laser based fiber Bragg grating writing, low-divergence resonator mirrors have to be employed…

waveguides of thicknesses of around
600 nm: Direct illumination of a grating
phase mask and imaging of a grating mask
by a Schwarzschild objective. Both methods
use the two first diffraction orders of the
grating to interfere on the polymer surface
while the zero order…

ures. Grating areas in the range of square
millimeters and even square centimeters are
possible, whereas gratings made by a
Schwarzschild objective are limited to areas
of a few hundred square micrometers in the
best case. However, the requirements for the
beam profile…

…homogenize the beam from a Lambda Physik LPF 220i F2 laser and to focus it on a 6 6-mm aperture for uniform illumination at the mask plane. A 25 Schwarzschild lens delivered uniform ±5 percent on-target fluence of 6 J/cm2 in a 0.25 mm 0.25-mm field. The system extends the possibilities for fabricating…
