Sapphire material
- Synthetic single-crystal sapphire (Al2O3) is
the leading material for highly advanced optical applications due to a
unique combination of excellent optical, physical and chemical properties.
It is transparent over a wide range of wavelengths from vacuum ultraviolet
to infrared regions (from 0.18 µm to 6 µm). Due to its hexagonal crystalline
structure, sapphire shows anisotropic behaviour in its optical and physical
properties. Therefore the exact characteristics of optical components made
from sapphire depend on the crystallographic direction relative to the
optical axis (C-axis, 0001). Sapphire possesses birefringence on all
directions except for the c-axis. Sapphire is the hardest among all oxide
crystals. Due to its extreme surface hardness, sapphire can be scratched by
only a few substances (for example, diamond and boron nitride). It's great
strength allows for the production of much thinner optical windows compared
to other materials. Yet another reason to employ sapphire at wavelengths
close to the transmission limit.
We can deliver the Sapphire material produced by two different methods of
sapphire growth:
Kyropoulos method: is used to produce a large boule of sapphire,
typically of a cylindrical form. Grown boule can be from 70 up to 300 mm in
diameter and up to 250 mm in height. Sapphire grown by this method normally
has a very high optical quality with low defect density with efficient
costs, and can be cut into wafers of any crystallographic orientation. This
method is applied for manufacturing substrates for blue LEDs and SOS wafers.
Stepanov method (EFG): a shaped growth technique used for growing
sapphire in near-net finished shape, including tubes, rods, sheets, and
fibers. This technique can also provide unique shapes and sealed assemblies.
By Stepanov method, ribbon crystals up to 500 mm long and 80 mm wide are
grown. Crystals grown by this method can have different crystallographic
orientations (A, R, random) and are mainly used for industrial & mechanical
applications, where good optical qualities are not important. Main applications of sapphire
Optical application
- Sapphire is a superior material for highly sophisticated
optical applications, because it is highly transparent at wavelengths of
light between 0.18 µm to 5.5 µm , as well as being five times stronger than
glass. High optical transmission of sapphire combined with the perfect
chemical durability, wear resistance and the ability to withstand high
temperatures made sapphire the leading material for sensor optics and
optical components for spectroscopy.
Mechanical application
- Sapphire is wide used for scratch proof windows in high
quality watches, scanner applications and other high wear applications and
for precision mechanical components, because its extreme hardness makes the
surface resistant to scratching.
High temperature and pressure application
- Sapphire has a unique combination of physical, chemical
and optical properties allowing it to withstand high pressure and thermal
shock. Sapphire has a melting point of over 2000 C°, making it ideal for
high-temperature applications. High pressure sapphire tubes and windows,
high strength and vacuum windows, high temperature sapphire windows are
small part of large range of optics in this specific field.
Chemical application
- Chemically inert to common acids and alkali at
temperatures up to 1000 °C, sapphire tubes, crucibles and other sapphire
optics are irreplaceable for different applications for chemical industry.
Sapphire is excellent for sprays and nozzles of all types, products
subjected to high temperatures or in contact with acids. Sapphire replaced
quartz ware to improve durability and reduce contamination while offering
good UV transmission.
Electrical application
- Due to its a high, stable dielectric constant, sapphire
is wide used for electronic substrates. Electrical properties of sapphire
are depend on crystallographic orientation. In addition, sapphire wafers are
used in the semiconductor industry as a substrate for the growth of gallium
nitride based devices LED (light emitting diodes).
Medical application
- Sapphire is often used in endoscopes lenses due to its
durability in contact with tissues and in sterilization environments such as
autoclaving. Also tips from sapphire are very good for various surgical
laser applications and sapphire light guides are commonly used in cosmetic
skin procedures.

Crystals
- Impex HighTech GmbH offers different kinds of crystals,
which can be mainly devided into three groups: Optical crystals, non-linear
crystals and laser crystals.
Our special „Bonded Laser Chip“ is displayed under the „Lasers“ link on the
right side of this page. Such chips are diffusion bonded Nd:YAG (laseractive)
with Cr4+:YAG absorber crystals. As such monolithic laser chips they are
allready correctly coated and key element of our pulsed laser series 1064-Q
and 532-Q. Optical Crystals

Flow tubes
- Cavity flow tubes for flash lamp pumped lasers
Cavity flow tubes (monoblocks), built as one solid optical element,
usually combine and perform the function of laser pump chamber, flow tube,
filter and reflector. A flow tube is machined out of a block or rod of
carefully selected high optical quality Quartz glass material, undoped or
doped with the appropriate rare earth or metal ions. We use chemical and
electro-chemical coatings with Silver and Copper or other layers to generate
the reflector surface.
Special reflectors for diode pumped lasers
Specular reflectors for diode pumped lasers consist of fused silica
quartz or sapphire tubes, the external surface of which is covered with
silver (high reflection Ag) coating with protecting layers. Several areas of
this reflector are open as a window for diode pumping. This kind of
reflectors would be produced with required window sizes and configuration in
accordance with the customer’s requirements.
Laser
- Impex HighTech
GmbH offers a complete range of laser systems from q-switched high energy to
very stable single frequency continuous wave diode pumped solid state laser
at different wavelength. We can offer custom specific parameters depending
on the integrated bonded crystal. The adhesive free diffusion bonding is
highly reliable and causes very low intra cavity losses at the bonding
interface. Therefore these laser are highly reliable and sought after in
industry and research.
By designing these lasers, the low cost, compactness, resistance against
mechanical stress and flexibility of the laser was our major concern. Where
high pulse intensities are needed, especially for mobile applications in
different fields. For example in Laser Induced Breakdown Spectroscopy (LIBS),
marking, micro machining, photonic crystal fiber pumping (super continuum
generation), Lidar, range finding and as seeding master oscillator for high
power solide state lasers. ELM1064
- These passively q-switched µ-chip lasers are all based on
our own bonded laser chip. A selection of these chips (which vary in terms
of length, output coupling and initial transmission) make up the base of our
product lines. The main is the ELM1064, which is available in a high energy
version above 210 µJ pulse energy and repetition rates of a few kHz and a in
low energy version (above 70 µJ / tens of kHz). The ELM1064 generates pulse
energies above 70 µJ and repetition rates of 20 kHz can easily be reached.
All lasers come with a computer control software for remote control of the
laser and all temperature settings. The pulse width is always below 5 ns.
These ELM1064 Lasers are well suited for LIDAR (light detection and
ranging), LIBS (Laser Induced Breakdown Spectroscopy) and for super
continuum generation with the use of a photonic crystal fiber (PCF). More
details can be found in the corresponding PDF datasheets. For different
specifications, please contact us directly.
ELM532
- Our passively q-switched ELM532 lasers are just a few cm
longer than the well known ELM1064 lasers. The frequency doubling of the
Nd:YAG laser is done with state of the art walk off compensation which leads
to a conversion efficiency of more than 50% by just single pass through a
non linear crystal. These ELM532 Lasers are well suited for LIDAR (light
detection and ranging) as well as LIBS (Laser Induced Breakdown
Spectroscopy) applications. We reached output powers up to 500 mW, but here
you will receive a much stronger pulse to pulse timing jitter. More details
can be found in the corresponding datasheets below. For different
specifications, please contact us directly. We also develop customer
specified laser systems.
ERB15
- We introduces The Unique and Universal Er:YAG laser
system ERB15 OEM, which is now the highest power and ultra shortest Pulses
available.
We have been supplying our ERB15 solutions for the research, medical and
industrial laser market for many years and now we use that experience to
offer our unique ER:YAG Laser with 2.94 µm with less than 60 ns Puls width
and 15 mJ Pulse energyat maximum repetition rate of 10 Hz.
The free-running Er:YAG laser designed for clinical use typically has a
pulse width of a few hundred microseconds. When such a long-pulsed radiation
is applied to the affected areas, the excess heat diffuses into the
surrounding healthy tissues, causing damage or necrosis. Therefore, it is
very important to develop a high-energy (high-peak-power) with short pulse
width it means, reduce the diffusion time for the treatment of hard tissue
with minimum lateral heat affecting.
More details can be found in the corresponding PDF datasheet below. For
different specifications, please contact us directly. We also develop
customer specified laser systems.
LD-SMART
- The Laser Diode Driver LD-SMART is designed to actuate
laser diodes (8Vx10A) or diode pumped solid state lasers through USB or
Bluetooth interface on a touch screen tablet or Smartphone via controlling
software. The possibility for the integration of the laser diode on board or
extrenally makes the LD-SMART unique. New feature of LD-SMART is the
Adaptive Temperature Control, whereas the operational temperature is adapted
by the current of the laser diode to achieve constant target wave length
with 12% more efficienty. This device contains up to three temperature
controllers and pulse triggering mode with internal & external TTL.
