BBO Crystal
BBO (ẞ-BaB2O4) mara mma dị mma na-enweghị klọọkụ na njikọtara nke ọtụtụ atụmatụ pụrụ iche: mpaghara nghọta zuru oke, akụkụ buru ibu, nnukwu ọnụọgụ na-enweghị mmezi, ọnụma mmebi dị elu, na ịdị n'otu nke kachasị mma. Ya mere, BBO na-enye uzo di nma maka ngwa anya di iche iche dika OPA, OPCPA, OPO wdg.
BBO nwekwara uru nke bandwidth na-anabata ikuku dị elu, ọnụ ụzọ mmebi na obere nnabata, yabụ dabara nke ọma maka mgbanwe ntụgharị nke ọnụ ọgụgụ dị elu ma ọ bụ radieshon ike, dịka ọmụmaatụ harmonic nke Nd: YAG, Ti: Sapphire na Alexander laser radies. BBO bụ kristal kachasị mma NLO maka ọgbọ harmonic nke ise nke ise: YAG laser na 213 nm. Ezigbo laser beam àgwà (obere ọdịiche, ọnọdụ dị mma, wdg) bụ isi ihe maka BBO iji nweta arụmọrụ dị elu.
Na mgbakwunye, nnukwu nzipu mgbasa ozi yana ntanetị oge, ọkachasị nso na UV, na-eme BBO zuru oke maka ugboro ugboro ugboro ugboro iji wee nwee ntụpọ ọkụ Dye, Argon ion na copper vepo laser. Enwere ike ịnweta ụdị 1dị nke mbụ (oo-e) na ụdị 2 (eo-e), na-abawanye ọnụ ọgụgụ nke uru maka ngwa BB dị iche.
Kpọtụrụ anyị maka ihe kachasị mma maka ngwa gị nke kristal BBO.
