BBO Crystal
BBO (ẞ-BaB2O4. Sabili da haka, BBO yana ba da mafita mai ban sha'awa ga aikace-aikace masu amfani da gani ba iri-iri kamar OPA, OPCPA, OPO da dai sauransu.
Hakanan BBO yana da fa'idar manyan faifai na karɓar zafi, ƙarancin lalacewa da ƙarancin sha, don haka ya dace sosai da sauyawar babban ganiya ko matsakaicin hasken wutar lantarki, kamar na zamani na Nd: YAG, Ti: Sapphire da kuma hasken Laser na Laser. BBO shine mafi kyawun garagon NLO don ƙarni na harmonic na Nd: YAG laser a 213 nm. Kyakkyawan katako na laser (ƙananan rarrabuwa, yanayin yanayi mai kyau, da sauransu) shine mabuɗin don BBO don samun ingantaccen juyawa.
Bugu da kari, babban watsa shirye-shiryen watsa shirye-shirye daidai da tsarin daidaituwa na zamani, musamman ma a cikin kewayon UV, yana sa BBO ya dace sosai da maimaita yawan yanayin Dye, Argon ion da kuma huhun huhun karfe. Dukkan nau'ikan 1 (oo-e) da Type 2 (e-e-e) masu dacewar ɓangarorin biyu ana iya samun su, suna ƙaruwa da dama don aikace-aikace daban-daban na BBO.
Tuntube mu don mafita mafi kyawun aikace-aikacen ku na lu'ulu'u na BBO.
