    BBO waa soo noqnoqoshada ultraviole cusub oo labanlaabaya crystal. Waa crystal uniaxial taban, oo leh index refractive caadiga ah (maya) ka weyn index refractive aan caadi ahayn (ne).Nooca I iyo nooca II ee isbarbardhigga wejiga waxaa lagu gaari karaa hagaajin xagal.
    BBO waa kristaalo NLO hufan oo loogu talagalay jiilka labaad, saddexaad iyo afraad ee iswaafajinta Nd: YAG lasers, iyo NLO crystal ugu fiican jiilka shanaad ee harmonic ee 213nm.Waxtarka beddelka oo ka badan 70% SHG, 60% THG iyo 50% ee 4HG, iyo 200 mW wax soo saarka 213 nm (5HG) ayaa la helay, siday u kala horreeyaan.
    BBO sidoo kale waa crystal wax ku ool ah oo loogu talagalay godka hoose ee SHG ee awoodda sare ee Nd: YAG lasers.Shaxda hoose ee SHG ee acousto-optic Q-switched Nd:YAG laser, in ka badan 15 W celceliska awoodda 532 nm waxaa soo saaray AR-dahaarka leh ee BBO crystal.Marka lagu shubo wax soo saarka 600mW SHG ee qaab qufulan Nd:YLF laser, 66mW wax soo saarka 263 nm waxaa laga soo saaray xagal-BBO ee Brewster-jaray oo ku yaal dalool koron oo dibadda ah.
    BBO waxa kale oo loo isticmaali karaa codsiyada EO. Unugyada BBO Pockels ama EO Q-Switchs waxaa loo isticmaalaa in lagu beddelo xaaladda polarization ee iftiinka dhex mara marka danab lagu dhejiyo electrodes ee crystals electro-optic sida BBO.Beta-Barium Borate (β-BaB2O4, BBO) oo leh jilayaasha hufnaanta ballaaran iyo heerarka isbarbardhigga wejiga, isugeynta weyn ee aan tooska ahayn, heerka waxyeellada sare iyo isku-dhafka indhaha ee wanaagsan iyo guryaha korantada-muuqaalka ah ayaa bixiya fursado soo jiidasho leh oo loogu talagalay codsiyada indhaha ee kala duwan ee aan tooska ahayn iyo codsiyada korantada.
    Astaamaha BBO Crystals:
    • Waji ballaadhan oo u dhexeeya 409.6 nm ilaa 3500 nm;
    • Gobolka gudbinta ballaaran laga bilaabo 190 nm ilaa 3500 nm;
    Isku-xidhka-jiilka-labaad ee wax ku ool ah (SHG) oo weyn oo qiyaastii 6 jeer ka weyn kan KDP crystal;
    Heerka waxyeelada sare;
    • Homogeneity sare ee indhaha oo leh δn ≈10-6 / cm;
    Heerkulka ballaaran-bandwidhth ee ku saabsan 55 ℃.
    Ogeysiis muhiim ah:
    BBO waxay leedahay u nuglaanta qoyaanka.Isticmaalayaasha waxaa lagula talinayaa inay bixiyaan xaalado qalalan labadaba codsiga iyo ilaalinta BBO.
    BBO aad bay u jilicsan tahay sidaas darteed waxay u baahan tahay taxaddar si loo ilaaliyo oogaheeda dhalaalaya.
    Marka xagal hagaajintu ay lagama maarmaan tahay, fadlan maskaxda ku hay in xagasha aqbalida ee BBO ay yar tahay.
