    Vitio

    BBO o se fou ultraviole taimi faʻaluaina faʻaluaina tioata. O se le lelei tioata uniaxial tioata, ma masani reva faʻasino igoa (leai) lapoʻa nai lo tulaga ese faʻasolosolo index (ne). Uma ituaiga I ma ituaiga II laʻasaga fetaui mafai ona maua i le tulimanu o le faʻamau. 
    BBO o se lelei tioata NLO mo le lona lua, lona tolu ma le fa tupulaga soʻofaʻatasi o Nd: YAG lasers, ma le sili tioata NLO mo le lona lima fealofani tupulaga i 213nm. O le liuaina sili atu nai lo 70% mo SHG, 60% mo THG ma 50% mo 4HG, ma 200 mW galuega faatino i le 213 nm (5HG) ua maua, faʻatulagaina.
    BBO o se lelei tioata foi mo le intracavity SHG o maualuga mana Nd: YAG lasers. Mo le vevesi SHG o se acousto-optic Q-fesuiaʻi Nd: YAG leisa, sili atu i le 15 W averesi mana i le 532 nm na faia e se AR-coated BBO tioata. A o pamuina e le 600 mW SHG galuega faatino o se mode-loka Nd: YLF leisa, 66 mW galuega faatino i le 263 nm na gaosia mai le Brewster-tulimanu-tipi BBO i totonu o fafo fafo resonant ana.
    E mafai foʻi ona faʻaaogaina BBO mo EO talosaga. O sela o le BBO Pockels poʻo le EO Q-Switches e suia ai le tulaga polarization o le malamalama e pasi atu pe a tuʻuina se voltage i electrodes o electro-optic crystals pei o BBO Beta-Barium Borate (β-BaB2O4, BBO) ma charactors lautele transparency ma vaega fetaui laina, tele nonlinear coefficient, maualuga faaleagaina faitotoʻa ma sili atu opitika homogeneity ma electro-opitiga meatotino maua matagofie avanoa mo eseese nonlinear opitika talosaga ma electro-optic talosaga.
    Vala o BBO Crystals:
    • Lautele vaega faʻafetaui vaʻaia mai le 409.6 nm i le 3500 nm;
    • Lautele felauaiga itulagi mai 190 nm i le 3500 nm;
    • Fuafua lelei le fefaʻatauaʻiga o le augatupulaga lona lua (SHG) tusa o le 6 taimi sili atu nai lo le KDP tioata;
    • Maualuga faʻaleagaina faitotoʻa;
    • Maualuga opitika homogeneity ma δn ≈10-6 / cm;
    • Lautele le vevela-bandwidth pe a ma le 55 ℃.
    Faasilasilaga taua:
    BBO e i ai le maualalo gofie i le susū. Ua fautuaina le aufaʻaoga e tuʻuina atu tulaga matutu mo le faʻaogaina ma le faʻasaoina o le BBO.
    BBO e agamalu lava ma o lea e manaʻomia ai puipuiga e puipuia ai ona luga luga.
    A tatau ona faʻatulagaina le tulimanu, faʻamolemole ia e manatua o le taliaina o le BBO e laʻititi.
