BBO Crystal
BBO (ẞ-BaB2O)4) waa buluug aan fiicnayn oo aan caadi ahayn oo ay weheliso dhowr astaamo u gaar ah: gobolka daahfurnaan ballaaran, baaxad is-waafajin ballaaran, isku-filnaansho ballaaran, isugeyn waxyeello weyn, iyo isku-dhafnaan heer sare ah. Sidaa darteed, BBO waxay siisaa xallin soo jiidasho leh codsiyada indhaha ee kala duwan ee aan tooska ahayn sida OPA, OPCPA, OPO iwm.
BBO sidoo kale waxay leedahay faa iidooyin balaaran oo aqbala kuleylka ballaaran, xaddiga waxyeelada sare iyo nuugista yar yar, sidaas darteed aad ayey ugu habboon tahay soo noqnoqoshada isku-darka sare ama shucaaca leysarka dhexdhexaadka ah, tusaale ahaan jiilka is-waafaqa ee Nd: YAG, Ti: Sapphire iyo shucaaca laser Alexandrite. BBO waa midka ugu fiican ee loo yaqaan 'NLO crystal' oo loogu talagalay jiilka shanaad ee is-waafajinta ee Nd: YAG laser at 213 nm. Tayada wanaagsan ee loo yaqaan 'laser beam' oo wanaagsan (kala duwanaansho yar, xaalad wanaagsan, iwm) waa furaha BBO si loo helo hufnaan sarreysa.
Intaa waxaa dheer, kala-qaadidda muuqaalka weyn iyo sidoo kale wajiga wajiga, gaar ahaan baaxadda UV, waxay BBO ka dhigeysaa mid ku habboon soo-noqnoqda soo-noqnoqda ee shucaaca dheecaanka ee loo yaqaan 'Dye', Argon ion iyo copper vepo laser radiation. Labada nooc ee 1 (oo-e) iyo Nooca 2 (eo-e) xaglaha wajiga u dhigma ayaa la heli karaa, iyagoo kordhinaya tirada faa'iidooyinka barnaamijyada kala duwan ee BBO.
