Remanufacture of a short pulse final focusing mirror, remove coating, refinish substrate and recoat.
Two short pulse beamlines require the use of an off-axis parabola (OAP) as the final focusing optic. Due to the optics proximity to target the surface becomes degraded over time due to target shrapnel and condensate from material vaporization.
The optics are 720 mm in diameter and have a specific surface profile and optical coating requirement. They either have a 1 Omega (1053 nm) or 2 Omega (527 nm) high reflectance coating with a specified laser damage threshold at the pulse length of use
