Features

Low Loss HR mirrors are essential in laser systems where the lowest
possible losses are required. Mirrors are manufactured with advanced
sputtering technology reach extremely high-quality specifications. Suchthin films feature higher density and durability than e-beam coatings,
making them resistant to environmental conditions such as heat,humidity and pressure. Mirrors reach highest reflectance (>99.9%) in acertain wavelength range and angles of incidence (AOI). Furthermore,
scattering is minimized which is usually a limiting factor for highreflectivity.

High Contrast
Thin Film Polarizers

Description
High Contrast Thin Film Polarizers (TFP) are made using advanced Ion
Beam Sputtering (IBS) coating technology. These thin film polarizers
separate s- and p-polarization components of high energy laser beams.
Due to very low losses they are perfect for intra and extra cavity usage.
Because of their high damage threshold and extinction ratio (>1000:1),
thin film polarizers are a good replacement for Glan laser polarizing
prisms or polarizing cube beam splitters. For optimal performance,
polarizers should be mounted in an appropriate holder allowing angularadjustment. We offer two types of high contrast polarizers: with higher
LIDT or higher contrast values.

Description
Polarizing beamsplitter cubes offer several advantages over platebeamsplitters. They are easy to handle, high contrast and high extinction
ratio polarizers that split a randomly polarized beam into two orthogonallinearly polarized components. These products are typically used in laserbeam separation, combination and optical-isolation applications. The
epoxy-free construction of the cubes enables a superior performance athigh energy levels.

Description

Features•

High extinction ratio•••

Wide wavelength range
Low transmitted wavefront distortion
High LIDT

Crystalline quartz waveplates are made from materials that have abirefringence property. Most common types are designed so that an
ordinary ray will exhibit a half (λ/2) or quarter (λ/4) wave retardation withrespect to an extraordinary ray. Such waveplates are used to rotate theplane of polarization, converting a linear polarization to a circular one andvice versa. Such elements are used for electro-optic modulations and as avariable ratio beamsplitter when used in conjunction with a polarization
cube. Although the latter two types of waveplates are the most common,
Altechna also oﬀers custom retardation values on request.
One of the most common arrangements of the waveplates is thezero order (ZO) air-spaced version. These waveplates are built of two
crystalline quartz plates with specific thicknesses and crossed axes, which
results in a zero order performance. This arrangement allows us to reacha better performance for a wider wavelength range and is less sensitive
to temperature changes when compared with low order (LO) waveplates.
High purity crystalline quartz materials and precise parallelism between
the two air-spaced plates allows the transmitted wavefront distortion tobe better than λ/10 at 632.8 nm.

PowerXP Motorized Attenuators
Description
Altechna offers four types of laser beam intensity attenuators for highenergy applications:
CA 8 mm – Compact version
CA 18 mm – Maxi Reflection/Transmission version
CA 18 mm – Maxi Transmission Collinear version
CA 18 mm – Maxi Cube version

Watt Pilot attenuators. New generation PXP units have upgraded beltdriven rotator mechanism for quick and precise laser beam intensity
control and also brand new electronics and control driver for moreconnectivity options and reliable long-distance communication.
PowerXP motorized attenuators are a reliable solution for industrial
applications. Each attenuator includes motorized rotating quartz λ/2phase waveplate, optically aligned to a single/dual thin film polarizers
or polarizing beamsplitting cube which separates the input beam into
individual s-polarized and p-polarized parallel or perpendicular output
beams.
Special PowerXP Transmission Collinear version includes an additional
uncoated UVFS window positioned at Brewster angle after the polarizer
to compensate the lateral beam shift caused by polarizing plate andguarantees less than 100 μm radial beam displacement between input
and output laser beam for ultra-precise applications.
High energy applications compatible optics, fast rotation speed ofPowerXP Maxi version, compensated beam displacement output ofMaxi Collinear version, convenient polarization separation angle ofMaxi Cube version and small footprint of Compact version makes
PowerXP motorized attenuators a go-to solution for power control,
attenuation, and beam-splitting in demanding laser processing
applications.

Fixed Ratio Beam
Expanders

Description
Fixed ratio beam expander is a device dedicated to increase the diameterof a laser beam.
Altechna’s beam expanders are assembled using one diverging and one
converging lens. As there is no focal point inside of the beam expander, it
can be used with high power laser sources. Special treatment of lenses andmechanics is performed for UV application to improve lifetime and LIDT of
the expander. Standard magnifications are from 1.1x to 5x. Beam expanders
for any wavelengths between 266 – 1064 nm are available upon request.
Features••••

Custom magnification and design on request
Extended lifetime and LIDT for UV applications
Individual reports of beam ellipticity, M2 and pointing stability parameters
Custom wavelengths are available in the range of 266-1064 nm

Variable Beam
Expanders

Description
Variable beam expanders are ideal for systems in which different
magnifications and precise control of laser beam divergence are
required. Altechna offers Galilean type variable beam expanders withhigh LIDT AR coatings that minimize ghost reflections. Our variable beam
expanders allow individual magnification and divergence adjustment.
Two main standard products change magnification in the range of 1x-4x
and 2x-8x.

Motorized Beam
Expanders

Description
Motorized Beam Expander (MBE) is a precision beam expander designed forautomated applications. Device allows rapid and independent divergenceas well as magnification adjustment during its operation. MBE featureshigh pointing stability as well as expansion accuracy. ±61 µm focal plane
deviation is ensured for 1x-2x model after warp-up using +160 mm focal
length F-theta lens and Ø4.9 mm input beam.
Moreover, high expansion repeatability and longevity of the product help
to increase the efficiency of the application as frequent calibration andreplacement can be avoided. In addition, MBE optical design enables it
to be used in high power laser applications as there are no internal foci.
