Diffractive polarizers by Jenoptik use especially designed nanostructures for producing high efficiency and polarization contrast.

Diffractive aspheric lenses are flat opticalelements that generate an aspheric wavefront. Such diffractive aspheric lenses serve as null lenses in precisioninterferometric tests for manufacturing high quality refractive aspheric lenses. They are also usedas aspheric elements in optical systems with unique aberration compensation properties.

Diffractive beam shapers are used to modify the intensityand phase profile of spatially coherent lasers, allowinga better control of the output beam. These optical elementsare most commonly used for the optimizationof energy distribution in laser applications where thecorrection of non-uniform and Gaussian beam profilescan lead to better overall efficiency and performance.Jenoptik designs high performance beam shapers tocreate uniform top-hat, circular, or rectangular profiles,as well as custom geometries.

Diffractive Beam Splitters are periodic phase structuresthat split the input beam into multiple diffractiveorders while retaining the divergence angle,diameter and polarization of the input beam.  Applications such as LIDAR, colour separation,materials processing, surgery or metrology canbenefit from the use of beam splitters to better distribute the energy emitted by a laser and thusimprove efficiency an performence. Furthermore processes like welding can show better results by using multiple laser beams with given spacing angles and power ratios.

The diffractive diffusers generate top-hatlike or custom intensity profiles with very sharp edges. Low scattering and sharp profile edges result in clearlyhigher efficiencies compared to conventional diffusers.  Diffractive diffusers may be used as a single opticalcomponent to generate the desired intensity profilein a larger distance.

Diffractive Line Generator Optics (LGO) transform a Gaussian laser beam into a homogeneous top-hat line profile.

Multipole pupil illumination patterns are required to achieve the highest resolution in mask projection systems. Diffractive Optical Elements (DOE) efficiently generate such patterns with high precision and uniformity. The use of high-quality materials for the Jenoptik DOE results in high lifetime even under intense ultraviolet laser irradiation.

High power lasers, such as Excimer, Nitrogen or diodepumped frequency tripled lasers are used in a diverserange of industrial and scientific applications becauseof their unique ability to deliver high pulse energies andhigh average power at UV wavelengths. Most applicationsfor these lasers require the output beam to bereshaped into a Gaussian profile to match the needs ofthe process.

Jenoptik dielectric pulse compression gratings are highly efficient and durable under high laser power densities. The efficiency advantage over metal gratings results in more than 20% additional output power in a typical CPA setup with four grating passes.
