    ʻO ka BBO kahi kristal hoʻopālua ultraviole frequency hou.Hiki ke kiʻi ʻia nā ʻano like ʻelua a me ke ʻano II ma ke kani ʻana o ke kihi.
    ʻO BBO kahi aniani NLO maikaʻi no ka lua, ke kolu a me ka ʻehā o ka hanauna harmonic o Nd:YAG lasers, a me ka aniani NLO maikaʻi loa no ka lima o ka hanauna harmonic ma 213nm.'Oi aku ka maika'i o ka ho'ololi 'ana ma mua o 70% no SHG, 60% no THG a me 50% no 4HG, a me 200 mW puka ma 213 nm (5HG).
    He aniani maikaʻi nō hoʻi ʻo BBO no ka intracavity SHG o nā lasers Nd:YAG kiʻekiʻe.No ka intracavity SHG o kahi acousto-optic Q-switched Nd: YAG laser, ʻoi aku ma mua o 15 W mana awelika ma 532 nm i hana ʻia e kahi aniani BBO i uhi ʻia e AR.I ka wā e puhi ʻia ai e ka 600 mW SHG pukana o ka mode-locked Nd: YLF laser, 66 mW output ma 263 nm i hana ʻia mai kahi Brewster-angle-cut BBO i loko o kahi lua resonant hoʻonui i waho.
    Hiki ke hoʻohana ʻia ʻo BBO no nā noi EO. Hoʻohana ʻia nā cell BBO Pockels a i ʻole EO Q-Switches e hoʻololi i ke kūlana polarization o ka mālamalama e hele ana ma laila ke hoʻopili ʻia ka uila i nā electrodes o nā kristal electro-optic e like me BBO.ʻO ka Beta-Barium Borate (β-BaB2O4, BBO) me nā kikoʻī ākea ākea a me nā pae hoʻohālikelike ʻana, ka nui nonlinear coefficient, ka paepae pōʻino kiʻekiʻe a me ka homogeneity optical maikaʻi loa a me nā waiwai electro-optical e hāʻawi i nā mea kūpono no nā noi optical nonlinear a me nā noi electro-optic.
    Nā hiʻohiʻona o nā Crystal BBO:
    • Hiki ke hoʻohālikelike ʻia ka pae ākea mai 409.6 nm a 3500 nm;
    • Māhele hoʻouna ākea mai 190 nm a 3500 nm;
    • ʻO ka helu lua-harmonic-generation (SHG) maikaʻi nui ma kahi o 6 mau manawa ʻoi aku ka nui o ka KDP crystal;
    • ka paepae pōʻino kiʻekiʻe;
    • Ka homogeneity optical kiʻekiʻe me δn ≈10-6 / cm;
    • Ka laulā wela-ākea o kahi o 55 ℃.
    Hoʻolaha nui:
    He haʻahaʻa ko BBO i ka makū.Manaʻo ʻia nā mea hoʻohana e hāʻawi i nā kūlana maloʻo no ka noi ʻana a me ka mālama ʻana o BBO.
    He palupalu ʻo BBO a no laila pono e mālama i kona mau ʻili i poni ʻia.
    I ka wā e pono ai ka hoʻololi ʻana i ke kihi, e ʻoluʻolu e hoʻomanaʻo i ka liʻiliʻi o ka ʻae ʻana o BBO.
