BBO Crystal
BBO (ẞ-BaB2O4) ndi galasi labwino kwambiri lopanda mawonedwe ophatikizidwa ndi zinthu zingapo zapadera: dera lowonekera bwino, magawo ofananira ndi magawo, kugwirizanirana kwakukulu, njira yolakwika yayikulu, komanso njira yabwino kwambiri yowonekera. Chifukwa chake, BBO imapereka yankho lokongola la mitundu yosiyanasiyana yosagwiritsidwa ntchito ngati OPA, OPCPA, OPO etc.
BBO ilinso ndi zabwino za bandwidth yayikulu yamavomerero, kuwonongeka kwakukulu komanso kuyamwa pang'ono, motero ndi koyenera kwambiri kutembenuka kwapafupipafupi kapena kuchepa kwa mphamvu yama radiation, mwachitsanzo, m'badwo wa harmonic wa Nd: YAG, Ti: Sapphire ndi Alexandrite laser radiation. BBO ndiye Crystal wabwino kwambiri wa NLO wam'badwo wachisanu wa Nd: YAG laser pa 213 nm. Ubwino wa mtengo wa laser (kusinthasintha pang'ono, mawonekedwe abwino, ndi zina) ndiye chinsinsi cha BBO kuti ipeze kutembenuka kwakukulu.
Kuphatikiza apo, kufalikira kwakanema kofananira komanso kufananizira magawo, makamaka mumtundu wa UV, kumapangitsa kuti BBO ikhale yoyenera kutalika mobwerezabwereza kwa Dye, Argon ion ndi Copper vapor laser radiation. Onse awiri Mtundu 1 (oo-e) ndi mtundu 2 (eo-e) ofanana omwe amatha kugwirizanitsidwa angathe kulandilidwa, ndikuwonjezera kuchuluka kwa maubwino osiyanasiyana ogwiritsira ntchito a BBO.
Lumikizanani nafe kuti mupeze yankho lanu labwino kwambiri la makhiristo a BBO.

Mfundo Zazikulu - BBO
• Malo owonekera poyera (189-3500 nm)
• Mitundu yayikulu yofananira (410-3500 nm)
• Maso apamwamba a homogeneity （δn≈10-6/cm)
• Kuthekera kwakukulu kwa SHG kokwanira (pafupifupi nthawi 6 ya KDP)
