Introduction | Laser Damage Threshold Mechanisms | Surface
For over 20 years TecOptics has been renowned for
supplying the pinnacle of ultrahigh damage threshold
laser optics and substrates. Tests at independent
government and commercial laboratories have consistently
found our components meet the highest requirements.
Recent developments at our facilities uncovered new
techniques that raised our damage thresholds
substantially above other optics suppliers. Our modern
computer-controlled coating machines handle up to
12" diameter substrates.
Standard Laser Optics
normally supplies the following types of Coated Laser
Laser Cavity Optics
Thin Film Polarizers
Coatings and Laser Damage
Through our ongoing research program on new materials,
innovative coating techniques, and sophisticated CAD-CAM
developments, the damage thresholds for TecOptics' laser
optics are at the highest levels in the industry. For
instance, independent laboratories have measured values
of >40 j/cm2 for our new Nd:YAG and Nd:glass
laser high reflectors.

addition to the thousands already in our database, we
will gladly design special coatings for unique
applications. If your coating requirement is not

happy to coat customer-supplied substrates. Because we
cannot know the quality of these substrates nor the
methods of surface preparation we are not able to
guarantee damage thresholds in these cases.
The choice of the dielectric coating materials depends on
many factors: wavelength, width of wavelength band,
substrate material, damage threshold required, the
atmosphere the coating will see (e.g. air, plasma,
corrosive gas), temperature of the component, etc.
Therefore we work with a wide variety of materials and
choose the appropriate ones for each application.
example, many excimer laser cavity mirrors face a
corrosive atmosphere of highly reactive fluorine or
chlorine ions. In these cases, fluoride rather than oxide
coatings must be selected. However, fluoride coatings are
typically not as hard as oxides. Thus, for non-corrosive
atmospheres, oxides should be chosen. TecOptics coating
specialists have been at the forefront of coating
engineering for over 20 years and will choose the most
appropriate materials for each application.
