BBO Crystal
BBO (ẞ-BaB2O4) he karaihe nonlinear tino pai me te whakakotahi o te maha o nga waahanga ahurei: te rohe whanui whanui, te waahanga -e-whanui whanui, te waahanga kore-whanui, te paepae kino kino, me te whakakikorua tino pai. Na reira, ka whakaratohia e BBO tetahi otinga ataahua mo nga momo kowhatu koretake kaore i te maera penei i OPA, OPCPA, OPO etc.
He painga ano hoki a te BBO ki te hōkaiipurangi whakaaetanga wera nui, te paepae kino kino me te aukati iti, na reira e tika ana mo te whakawhitinga faafariu o te tihi teitei, ko te toharite taiaho whakaheke hiko ranei, hei tauira, te whakangao kino o Nd: YAG, Ti: Sapphire me te Alexandrite laser radiation. Ko te BBO te karaihe pai a NLO mo te whanau tuarima o te whakatupuranga Nd: YAG laser i te 213 nm. Ko te kounga kurupae laser pai (rereketanga iti, pai te ahuatanga o te momo, me etahi atu) ko te mea nui mo te BBO kia whiwhi i te mahi tino rereketanga.
Hei taapiri, ko te awhi whakawhiti tino nui tae atu ki te whakauru i te wahanga, ina koa i te awangawanga UV, e tika ana te BBO e tika ana mo te whakamaarua o te waipara, te Argon ion me te kopere whero taiaho radiation. Ko nga momo Momo 1 (oo-e) me te Momo 2 (eo-e) nga koki e rite ana, ka taea te whiwhi, me te whakanui ake i te maha o nga painga mo nga tono rereke a BBO.
Whakauru mai ki a maatau mo te otinga tino pai mo to tono tioata BBO.
