    BBO ndi yatsopano yama ultraviole pafupipafupi. Onse mtundu I ndi mtundu wachiwiri wofananira gawo utha kufikiridwa ndikutumiza ngodya. 
    BBO ndi NLO kristalo yothandiza m'badwo wachiwiri, wachitatu ndi wachinayi wa harmonic wa Nd: YAG lasers, ndi kristalo yabwino kwambiri ya NLO m'badwo wachisanu wa harmonic ku 213nm. Kutembenuka mtima kopitilira 70% kwa SHG, 60% kwa THG ndi 50% ya 4HG, ndi 200 mW zotulutsa ku 213 nm (5HG) zapezeka, motsatana.
    BBO ndi kristalo woyenera wa intracavity SHG yamphamvu yayikulu Nd: YAG lasers. Za intracavity SHG ya acousto-optic Q-switched Nd: YAG laser, yopitilira 15 W pafupifupi mphamvu ku 532 nm idapangidwa ndi kristalo wokutira wa BBO. Ikapopedwa ndi 600 mW SHG yotulutsidwa ndi Nd: YLF laser, kutulutsa kwa 66 mW pa 263 nm idapangidwa kuchokera ku Brewster-angle-cut BBO mu mphako yakunja yolimbitsa.
    BBO itha kugwiritsidwanso ntchito pakugwiritsa ntchito EO. Maselo a BBO Pockels kapena EO Q-Swichi amagwiritsidwa ntchito kusintha magawanidwe a kuwala komwe kumadutsa pomwe magetsi agwiritsidwa ntchito pama elekitirodi amakristasi ama electro-optic monga BBO. Beta-Barium Borate (β-BaB2O4, BBO) yokhala ndi ziwonetsero zowonekera bwino ndi magawo ofananira magawo, coefficient yayikulu yopanda malire, malire owonongeka kwambiri komanso mawonekedwe abwino ophatikizika ndi zamagetsi zimapereka mwayi wosangalatsa wa mitundu ingapo yamagetsi osagwiritsa ntchito ntchito zamagetsi ndi zamagetsi zamagetsi.
    Makhalidwe a Makandulo a BBO:
    • Gawo lotakata lomwe lingafanane kuchokera ku 409.6 nm mpaka 3500 nm;
    • Chigawo chachikulu chotumizira kuchokera ku 190 nm mpaka 3500 nm;
    • Chowonjezera chokwanira chachiwiri cha harmonic-generation (SHG) chokwanira pafupifupi kasanu ndi kamodzi kuposa KDP kristalo;
    • Kuwonongeka kwakukulu;
    • Kugwirizana kwakukulu ndi opticaln ≈10-6 / cm;
    • Kutentha kwakukulu -kuzungulira kwa pafupifupi 55 ℃.
    Chidziwitso chofunikira:
    BBO imatha kukhudzidwa ndi chinyezi. Ogwiritsa ntchito amalangizidwa kuti apereke zowuma pakugwiritsa ntchito ndikusunga BBO.
    BBO ndiyofewa motero imafunikira zachitetezo kuti iteteze malo ake opukutidwa.
    Pamafunika kusintha kwa ngodya, chonde kumbukirani kuti mbali yovomerezeka ya BBO ndiyochepa.
