PowerPhotonic Multi-spot Generators are freeform diffractive optical elements (DOEs) designed to transform a single mode input beam into a multi spot array in the focal plane of a lens. The currently available output spot configurations are: (i) 1D line of spots, (ii) 2D rectangular array of spots, (iii) Hexagonal array of spots.

All three configuration types are available as custom designs for specific input wavelength, number of output spots and spot separation. The freeform grating structure design allows for much higher diffraction efficiencies than are available from commonly available traditional binary
gratings, with efficiency values approaching mathematical design limits. Multi-spot generators are increasingly important in applications that require parallel processing from a single laser. One such application is the surface micro-structuring of metal to produce, for example hydrophobic surfaces, using a femtosecond laser. Multi-spot Generators are manufactured on fused silica, which has intrinsically high power-handling capabilities in both pulsed and CW operating regimes across a wide bandwith.
