Introduction | Laser Damage Threshold Mechanisms | Surface Handling
High power lasers do not like contaminants! When the
laser beam meets a surface, any foreign particle is
likely to burn, splatter, explode or otherwise be
destroyed, to the detriment of the coating. During the
manufacturing process and through the finished optics
being sealed in air-tight bags, TecOptics follows the
highest precautions to prevent any unwanted material from
settling on the surfaces. However, that is not enough.
When the optics arrive at their destination and they are
removed from their packing, the technical personnel there
must also be extremely careful. Here are some
- Never touch
a coated surface. Body oils from finger tips can
etch a coating, change its properties, and act as
a damage center.
- Only handle optics
at the edges and with clean hands and gloves.
Oils and grease can slowly migrate around the
edge onto the surface.
- Work in a clean
atmosphere. If dust or airborne contaminants
(such as oils in the air) settle on the optic's
surface the likelihood of laser damage increases
