I-BBO Crystal
I-BBO (ẞ-BaB2O4) I-crystal ebalaseleyo ye-nonlinear ngokudibanisa inani leempawu ezizodwa: indawo ebonakalayo ngokubanzi, uluhlu olubanzi lwesigaba esilinganayo, intsebenzo enkulu yokungalingani, umqobo omkhulu wentsebenzo, kunye ne-homogeneity entle. Ke ngoko, i-BBO ibonelela ngesisombululo esithandekayo kwizicelo ezahlukeneyo ze-nonlinear ezifana ne-OPA, OPCPA, OPO njl.
I-BBO ikwanazo ne-bandwidth enkulu yokwamkelwa kwe-thermal, umqobo omkhulu wokumitha kunye nokufakwa okuncinci, ngoko kufanelekile kakhulu ukuguqulwa rhoqo kwe-peak okanye i-radiation ye-avareji yamandla ombane, umzekelo isizukulwane se-injonic yeNd: YAG, Ti: Sapphire kunye ne-Alexandrite laser radiation. I-BBO yeyona kristali ye-NLO yeyona ilungileyo yesihlanu se-Nd: YAG laser kwi-213 nm. Umgangatho oluhle lomgangatho we-laser (ukwahluka okuncinci, imeko elungileyo yemeko, njl.) Sisitshixo se-BBO ukufumana uguquko oluphezulu.
Ukongeza, uluhlu olubanzi lokuhambisa oluhamba kunye nokudityaniswa kwesigaba, ngakumbi kuluhlu lwe-UV, lwenza ukuba i-BBO ilungele ngokufanelekileyo ukuphindaphinda kabini kwidayyi ye-Dye, Argon ion kunye ne-Copper vapor laser radiation. Zombini zohlobo lwe-1 (oo-e) kunye nohlobo lwe-2 (e-e) yokutshatisa ama-angles anokufumaneka, okonyusa inani lezibonelelo zezicelo ezahlukeneyo ze-BBO.
Nxibelelana nathi ngesona sisombululo sigqibeleleyo sokusetyenziswa kweekristali ze-BBO.
