Laser gratings Pulse compression and wavelength selection

High-efficiency pulse compression gratings can be manufactured up to a size of 240 x 240 mm with homogeneous grid patterns. Typical line counts for pulse compression applications are between 1000 and 2500 grooves per mm. In addition to flat substrates, you can choose concave, convex and free-form substrates.

Laser gratings from ZEISS are available for spectral ranges between 400 nm and 2 μm. The function-determining parameters are:

✔ line density
✔ furrow profile
✔ the resulting diffraction efficiency
✔ wavefront accuracy
✔ resolving power
✔ imaging properties
✔ substrate material
✔ the resulting radiation resistance
✔ several coatings like Al, Au and numerous AR coatings
