High Energy Laser Gratings
Laser gratings are used for selected frequency, pulse compression and sampling in laser systems. Now we can rule high energy laser gratings on metal substrate. The maximal dimensions of these gratings are 300×300mm2. Three-dimensional configuration of laser gratings by AFM is shown in figure.
Note: Such grating must be ordered in advance. Groove density, wavelength and ruled area can be selected. Additionally, we can manufacture concave metal grating with large curvature radius. Several examples of grating specifications are listed in the following table.
