Diffusion bonding

Supplier: LightOptronics Aust.
19 August, 2008

Northrop Grumman Synoptics offers its customers the ability to grow, fabricate, coat, and diffusion bond solid-state laser materials.

Optical properties of YAG bonds:

  • Transmitted wavefront distortions low Peak to Valley.
  • Opto-lase grade wavefront distortion achieved in bonded rods.
  • Mean stress birefringence decreases > 25% below as-grown contacted crystals following bonding heat treatment.
  • Loss contribution of bonds is negligible.

High strength YAG bonds:

  • >30% higher average strength in flexure tests than competitor bonds.
  • Bond failures do not originate at the bond interface.
  • Increased reliability indicated by higher Weibull modulus values.
  • All SYNOPTICS bonds pass boiling water thermal shock testing.
  • aterials available for bonding:
  • All garnet materials (Nd:YAG, CTH:YAG, Er:YAG, GGG)
  • Ceramic Nd:YAG
  • Fluoride materials (Nd:YLF)
  • Contact SYNOPTICS for bonding of other materials
