Damage Thresholds of Diffractive Optical Elements
Holo/OR: Quality Is Not Just a Promise; It Can Be Measured
The diffractive optical elements (DOEs) from Holo/OR are used to change the beam profile or split the beam in high-power lasers. They consist of fused silica, sapphire, and ZnSe substrates, into which a grating structure is etched. The DOEs are then coated – similar to a laser optic.
The maximum laser power at which DOEs can be used has been discussed often in the past: The question was whether the grating structure or the coating limited the damage threshold. Experience has shown that the coating limits the damage threshold.
HoloOr now has official proof: indeed, the structures do not have any effect on the damage threshold.
The exact measurement results and further information can be found in the datasheet, or inquire with us directly.
