Properties of Composites

Although there are differences between composites, the following summary of properties applies to most representative combinations:

Mechanical and Thermal

  • Flexural strength: Same as non-composite control samples
  • Thermal shock resistance: Same as non-composite controls; no separation at interface during failure
  • Can be finished and optically coated like conventional crystals

Optical Properties

  • Transmitted wave front unchanged; may actually be improved in long rods by selective arrangement of individual components with respect to each other
  • Negligible stress birefringence

Interface Properties

  • Very high laser damage resistance
  • Negligible scatter or absorptive loss
  • Fresnel reflection corresponding to difference in refractive index of components
