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 suggested that the coating limits the damage threshold.
Holo/Or now has officiall proof: indeed, the structures do not have any effect on the damage threshold. The exact measurement results and further information are available at the distribution partner LASER COMPONENTS.
