| Laser Ceramics Accuratus
has been supplying ceramics to the laser industry since it’s founding
in 1977. Accuratus personnel helped develop ceramic solutions for some
of the earliest laser devices. Accuratus continues to provide unique,
cost effective solutions for the challenges faced by laser and optical
system designers. Solid State Lasers
Accuratus has a unique highly diffuse reflectance material called
ACCUFLECT developed specifically for high energy flashlamp pumped laser
cavities. It’s Lambertian behavior makes it ideal for close coupled
cavity designs where output beam energy profile is critical. High
reflectance assures you of maximum wall plug efficiency from your laser
system. Visit our standard products page and case studies page for complete details on ACCUFLECT. | Two types of Accuflect are available: | | B6 | G6 | | Porous, unglazed | Glazed | | Designed for use in dry cavities and areas where there is no contamination. | Developed
for use in liquid cooled cavities and applications where contamination
is likely. | | Sizes up to 76 mm (3") diameter and 380 mm (15") long can be produced. | 
Excimer Lasers
Accuratus helped design and build the first generation ceramic
insulators used in excimer cavities. Forward thinking designers
consulted with Accuratus personnel to develop a manufacturable and cost
effective component. Proper selection of material type eliminated the
contamination and arcing problems inherent with the polymeric designs
then in use. The use of aluminum oxide ceramics virtually eliminated
contamination of the laser gas greatly extending gas lifetimes. Using
ceramic also cured the high voltage breakdown that was causing
significant down time in early generation excimers. Derivatives of this
early design continue in use today. CO2 Lasers
Accuratus has a long history supplying ceramic to the carbon dioxide
and similar gas lasers. Free space and waveguide designs are routinely
produced. Cylindrical, flat plate, straight and folded designs are
typical. Components used in flowing gas and sealed off systems are
supplied. Discriminating manufacturers relying on us for high quality
beam profiles have used our services for years. Aluminum oxide and
beryllium oxide are supplied depending upon output wavelength and heat
dissipation requirements. Cylindrical designs up to 600 mm (24") length
in single piece can be produced. Slab designs up to 600 mm (24") long
and 255 mm (10") wide can be produced. Folded designs with up to 50
folds have been produced although typically less than 6 folds are used. Ion Lasers
Accuratus personnel designed and produced the early generation
beryllium oxide based ion laser plasma tubes. To this day, Accuratus
maintains an important presence in the ion laser market supplying
superior quality tubes for both high power and capillary bore ion
tubes. Single piece tubes can be produced up to 255 mm (10")
long. Bore diameters range from 0.75 mm (.03") to 2.5 mm (.100"). HeNe Lasers
Accuratus manufactures pyrex tubes used for high-end distance
measurement lasers. Extremely precise and repeatable bore straightness,
and end face perpendicularity and parallelism are critical to the
measuring system. Accuratus quickly developed a set of cost effective
fabrication and inspection techniques to allow the customer to bring a
new, enhanced product to the marketplace. Semiconductor Lasers
Accuratus supplies mounts and submounts in high thermal conductivity
ceramics for the high powered diode laser market. Materials of
construction include beryllium oxide and aluminum nitride. Metallized
surfaces can be supplied with thick film deposited conductors or thin
film conductors. Additionally, small metallized submounts in aluminum
oxide are produced to support the photodetectors used for feedback
control in packaged laser systems. Typical sizes range from 0.25 mm
(.01") square to 19 mm (.75") square with thicknesses from 0.127 mm
(.005") to 1.5 mm (.06"). Other sizes and geometries are available. System Components
Ceramics are supplied for applications other than the laser in many
systems. The unique properties offered by ceramics are often taken
advantage of by system designers. Some ceramic applications include
high stability interferometer supports, thermally conductive lens
mounts, low mass/high stiffness mirror substrates, apertures, high
voltage electrical insulators for pockels cells and transparent crystal
mounts for doublers and triplers. See also: Materials > Accuflect
