λ/20 High Power Laser Line Windows
• 1 mm Thickness for Limited GDD
• Low Loss Broadband IBS Anti-Refl ection Coating
• Designs for Wavelengths from 370 - 2200 nm
TECHSPEC® Ultrafast Thin Windows are designed
with a 1 mm thickness to have limited group delay dispersion
(GDD), making them ideal for ultrafast laser
applications. These thin windows are available coated
on both surfaces with an ion-beam sputtered (IBS)
broadband antirefl ection coating optimized to provide
low refl ectance at wavelength ranges between 370 -
2200 nm. The IBS coating process also provides these
windows with lower absorption losses and scatter
than conventionally coated anti-refl ection windows.
TECHSPEC® Ultrafast Thin Windows can also be used
in general optical applications that require high-performance
optical windows with a small form factor. Uncoated
Thin Window substrates (UV Fused Silica or IR
Grade Fused Silica) are available to off er the fl exibility
of custom coatings to meet your application requirements,
please contact us for more information.

• <0,1% Refl ectivity Laser Line Coatings
• Nd:YAG and Yb:YAG Wavelength Options
• 10-5 Surface Quality Substrates
TECHSPEC® λ/10 Ultra-Low Refl ectivity Windows
feature anti-refl ection coatings with refl ection lower
than 0.1% at the design wavelength. These windows
feature high quality fused silica substrates with λ/10
surface fl atness and 10-5 surface quality to minimize
scatter. With ultra-low refl ectivity and high damage
thresholds, these windows are ideal for integration
into laser systems to virtually eliminate surface refl ections.
TECHSPEC® λ/10 Ultra-Low Refl ectivity Windows
are available in a range of laser V-Coats from
266 nm to 1064 nm for compatibility with Nd:YAG
and Yb:YAG laser sources. Imperial diameter sizes
from 12,7 mm to 50,8 mm are available.

Available
• Low Auto-Fluorescence
• High Damage Threshold
TECHSPEC® λ/20 High Power Laser Line Windows
feature a high effi ciency, high damage threshold Vcoating
to maximize transmission at the design wavelength.
Damage thresholds ranging from 2 - 10J/cm2
allow for easy integration into most Nd:YAG laser systems.
The coating is deposited on a precision excimer
grade UV grade fused silica substrate for excellent
thermal stability, low wavefront distortion, and ultralow
auto-fl uorescence.
