description:
BiB3O6 (BIBO) Crystal

BIBO( BiB3O6) is a newly developed nonlinear Optical Crystal. It possesses large effective nonlinear coeffcient,high damage threshold and inertness with respect to moisture.Its nonlinear coefficient is 3.5-4 times higher than that of LBO,1.5-2 times higher than that of BBO. It is a promising doubling crystal to produce blue laser.The top-seeded solution growth (TSSG) technique is used at CASTECH for the growth of BIBO single crystals.

CASTECH offers

  • Strict quality control;
  • Large crystal size up to 10x10x15mm3
  • AR-coating,mounts and repolishing services;
  • Fast delivery
