IBS optics for high-power lasers in material processing
Increase in laser fluence requires new coating options
Author: Barbara Herdt, LASER COMPONENTS Germany
Published: LP.PRO 05/2021, WEKA-Verlag
High-power lasers in femtosecond cycles- optics for laser material processing are subject to very different technical requirements. The IBS (ion beam sputtering) process offers manufacturers many options for achieving parameters that cannot be achieved with conventional coating methods, e.g., at high laser fluence.

Product Overview
Beyond Borders
As for the lenses only high-quality substrates are used for the windows.
Achromatic waveplates consists of two plates.
Aspherical lenses correct aberrations, which in monochromatic light include image sharpness errors and distortion.
Additional components for the expansion of a laser system: Here you will find beam expanders, z-axes Shift, and beam tubes.
Laser beam directing components direct or deliver the laser beam to the workpiece.
Beam expander for CO2 lasers with fixed, variable or zoom magnification and ZnSe optics.
Beam expanders with fixed or adjustable magnification levels.
Beam splitters for separating a beam into two equal parts without changing the polarization
Brewster plates are used to separate s- and p-polarized light.
Broadband filters allow wide wavelength ranges of incident light to pass through; in selected regions of the spectrum, these filters block the light.
Cavity end mirrors are used to generate the laser beam in the resonator.
Color glass filters are highly absorbing long-pass filters that are polished on both sides.
