BBO Crystal
BBO (ẞ-BaB2O4) ke kristale e ntle e se nang mabitso e nang le likarolo tse 'maloa tse ikhethang: sebaka se pepeneneng sa ho pepeseha, likarolo tse pharalletseng tse tšoanang, tšebelisano e kholo e senang lebelo, tšitiso e kholo ea tšenyo, le homogeneity e ntle. Ka hona, BBO e fana ka tharollo e khahlehang bakeng sa lits'ebetso tse fapaneng tsa marang-rang tse sa bonahaleng tse kang OPA, OPCPA, OPO jj.
BBO e boetse e na le melemo ea bandwidth e kholo ea ho amohela mocheso, lebelo le tebileng la tšenyo le ho monya ho fokolang, ka hona e loketse haholo bakeng sa phetoho ea khafetsa ea tlhoro e phahameng kapa mahlaseli a matla a laser ka mohlala, molumo oa kotsi oa Nd: YAG, Ti: Sapphire le Alexandrite laser radiation. BBO ke kristine e ntle ka ho fetisisa ea NLO bakeng sa moloko oa bohlano oa Nd: YAG laser ho 213 nm. Boleng ba boleng ba laser e ntle (phapang e nyane, boemo bo nepahetseng ba boemo, jj.) Ke senotlolo sa BBO ho fumana katleho e phahameng ea phetoho.
Ntle le moo, phallo e kholo ea phetisetso ea mmala hammoho le likarolo tse tsamaellanang, haholoholo ea UV, e etsa hore BBO e tšoanelehe hantle bakeng sa ho imeloa khafetsa ha radiation ea Dye, Argon ion le Copper vapor laser. Ka bobeli Mofuta oa 1 (oo-e) le mofuta oa li-angles tse tsamaeang ka mohato oa bobeli li ka fumanoa, o eketsa palo ea melemo ea lits'ebeliso tse fapaneng tsa BBO.
Ikopanye le rona bakeng sa tharollo e nepahetseng bakeng sa ts'ebeliso ea hau ea likristale tsa BBO.
