Other Products & Services

Onyx can cut and dice Adhesive-Free Bond (AFB®) composite YAG and AFB® composite YAG/sapphire components, as well as other material combinations. We can cut and dice waveguiding structures, passively q-switched microchips, and others.

In-House Machine Shop
Onyx is fully outfitted with its own in-house machine shop, which supplies custom-manufactured tooling for our various manufacturing processes. The ability to have project-specific tooling fabricated on the premises aids in the efficient manufacture of our AFB® optical components.

Measurement Capabilities
Onyx has many in-house measurement capabilities, including:

  • Measurements to sub-micron accuracies
  • 0.3 – 2.7 µm spectrophotometer tracing (full and narrow range scans) for absorption coefficient determination
  • Stress birefringence measurements

Mechanical properties

  • Fracture strength with sample preparation according to ASTM C1161-02c by four-point bending with full documentation and Weibull analysis on Onyx-prepared samples
  • Equi-biaxial fracture test according to ASTM C1499-05
  • Elastic modulus of laser crystals and optical ceramics by precision interferometric strain measurement with complete documentation
  • Fracture toughness of customer supplied material

Thermal properties

  • Thermal conductivity as function of temperature at near room temperature and above for crystals or glasses
  • Thermal conductivity of AFB® composites of crystals or glasses at room temperature, useful for evaluating heat transfer coefficient between doped and undoped or differently doped crystals or glasses
  • Heat transfer between AFB® crystal or glass composites with optical coating at interface at room temperature

Optical properties

  • Transmitted wavefront at 633 nm

Onyx is well-equipped with polishing capabilities, as polishing is a critical aspect of our AFB® process. We can provide optical finishing for our AFB® composites and offer polishing services for non-composites. Specific capabilities include component thicknesses to tens of microns and barrel polishing of rods. Our polishing averages 2-3 Å surface roughness.

X-Ray Orientation
Onyx's x-ray equipment allows us to measure the orientation axes of crystalline materials quickly and accurately. This is a useful tool for verification during incoming inspection, as well as for confirming crystals with non-standard orientations. It is also helpful in the design of our AFB® Walk-Off Corrected (WOC) composites.
