    BBO shine sabon lu'ulu'u mai sau biyu na lu'u-lu'u.Wannan mummunan lu'ulu'u ne na uniaxial, tare da maɓallin nuna ƙyama na yau da kullun (a'a) ya fi girma girma mai ban mamaki (ne). Dukansu nau'ikan I da nau'in II iri iri ɗaya ana iya samun su ta hanyar kunna kusurwa. 
    BBO lu'ulu'u ne mai inganci na NLO don ƙarni na biyu, na uku da na huɗu na jituwa na Nd: YAG lasers, kuma mafi kyawun NLO lu'ulu'u na ƙarni na biyar mai jituwa a 213nm. Canza ingancin sama da 70% na SHG, 60% na THG da 50% na 4HG, kuma an samu 200 mW fitarwa a 213 nm (5HG), bi da bi.
    BBO kuma ingantaccen lu'ulu'u ne don ƙwaƙwalwar SHG na babban ƙarfin Nd: YAG lasers. Don intracavity SHG na acousto-optic Q-switched Nd: YAG laser, sama da 15 W matsakaita ƙarfi a 532 nm an samar da shi ta hanyar BBO mai rufin AR. Lokacin da aka buga shi ta hanyar 600 mW SHG fitarwa na yanayin da aka kulle Nd: YLF laser, fitowar 66 mW a 263 nm an samar da shi daga BBO mai yanke-kwana-BBO a cikin rami mai ƙarfin haɓaka na waje.
    Ana iya amfani da BBO don aikace-aikacen EO.BBO Pockels cells ko EO Q-Switches ana amfani dasu don canza yanayin nuna haske na wucewa ta ciki lokacin da ake amfani da ƙarfin lantarki akan wayoyin lantarki na kristel na lantarki kamar BBO. Beta-Barium Borate (β-BaB2O4, BBO) tare da cikakkun bayanai masu haske da jeri jeri jeri, babban haɗin kai mara daidaituwa, ƙofar lalacewa mai kyau da daidaituwa mai kama da juna da kayan aikin lantarki suna ba da dama mai kyau don aikace-aikace iri-iri marasa amfani da aikace-aikace na lantarki.
