    BBO ke kristale e ncha e kopanyang makhetlo a mabeli ea ultraviole. Ke kristale e mpe e sa lumellaneng, e nang le index e tloaelehileng ea refractive (no) e kholo ho feta index e sa tloaelehang ea refractive (ne). Bobeli ba mofuta oa I le mofuta oa II oa mohato o lekanang o ka fihlelleha ka ho hlophisa angle. 
    BBO ke kristale ea NLO e sebetsang hantle bakeng sa moloko oa bobeli, oa boraro le oa bone oa harmonic oa Nd: YAG lasers, le kristale e ntle ka ho fetisisa ea NLO bakeng sa moloko oa bohlano oa harmonic ho 213nm. Ts'ebetso ea phetoho e fetang 70% bakeng sa SHG, 60% bakeng sa THG le 50% bakeng sa 4HG, le tlhahiso ea 200 mW ho 213 nm (5HG) e fumanoe, ka ho latellana.

    BBO e ka sebelisoa bakeng sa lits'ebetso tsa EO. Lisele tsa BBO Pockels kapa EO Q-Swichi li sebelisoa ho fetola boemo ba khanya ea leseli e fetang ka eona ha motlakase o sebelisoa ho li-electrode tsa likristale tsa electro-optic joalo ka BBO. Beta-Barium Borate (β-BaB2O4, BBO) e nang le ponaletso e pharalletseng le mekhahlelo e lekanang, likarolo tse kholo tse se nang mohala, tšenyo e phahameng le homogeneity e ntle ea Optical le thepa ea electro-optical e fana ka menyetla e metle bakeng sa lits'ebetso tse fapaneng tse sa sebetseng tsa Optical le likopo tsa electro-optic.
    Likarolo tsa BBO Crystals:
    • Karolo e pharalletseng ea sebaka se bapisoang ho tloha ho 409.6 nm ho isa ho 3500 nm;
    • Sebaka se pharaletseng sa phetisetso ho tloha 190 nm ho isa 3500 nm;
    • Sekhahla se seholo se sebetsang hantle sa moloko oa bobeli oa li-harmonic (SHG) se ka bang makhetlo a 6 ho feta sa kristale ea KDP;
    • Tšitiso e phahameng;
    • Homogeneity e phahameng ea optical le δn ≈10-6 / cm;
    • Mocheso o pharaletseng-bandwidth e ka bang 55 ℃.
