EPIC Technology Meeting on Industrial Laser Processes

Aspherical lenses correct aberrations, which in monochromatic light include image sharpness errors and distortion.

Brewster plates are used to separate s- and p-polarized light.

Cavity end mirrors are used to generate the laser beam in the resonator.

ROUND AND RECTANGULAR CYCLINDER LENSES ARE USED TO CREATE LINES / BEAM EXPANSIONS IN ONE DIRECTION.

DIAGNOSTIC BEAM SPLITTERS FOR PROCESS MONITORING

combine or separate two or more beams with different wavelengths.

Many corrections can be made with a single diffractive element.

DOEs is advantageous when one element is needed to produce several beams.

Plastic DOEs for beam shaping or beam splitting at low or medium power.

For the typical wavelength range in the near and far IR

For the typical wavelength range in the far IR (2.94 µm)

Selectively changing the profile. DOEs are used for optimized laser cutting, laser drilling, and material ablation.
