I-BBO iyikristalu entsha ephindaphindwayo ye-ultraviole frequency.Iyikristalu e-negative uniaxial, enenkomba evamile ye-refractive (cha) enkulu kune-extraordinary refractive index (ne).Kokubili ukufanisa kwesigaba I kanye nohlobo lwe-II kungafinyelelwa ngokulungisa i-engeli.
I-BBO iyikristalu ye-NLO esebenza kahle yesizukulwane sesibili, sesithathu nesine se-harmonic se-Nd:YAG lasers, kanye nekristalu ye-NLO ehamba phambili yesizukulwane sesihlanu se-harmonic ku-213nm.Ukusebenza kokuguqulwa okungaphezulu kuka-70% ku-SHG, u-60% we-THG kanye no-50% we-4HG, kanye nokukhishwa kwe-200 mW ku-213 nm (5HG) kutholiwe, ngokulandelanayo.
I-BBO futhi iyikristalu esebenzayo ye-intracavity SHG yamandla aphezulu Nd:YAG lasers.Nge-intracavity SHG ye-acousto-optic Q-switched Nd:YAG laser, amandla angaphezu kuka-15 W isilinganiso esingu-532 nm akhiqizwe ikristalu ye-BBO ehlanganiswe nge-AR.Uma iphampulwa ngu-600 mW SHG ophumayo wemodi ekhiyiwe ye-Nd:YLF laser, okukhiphayo okungu-66 mW ngo-263 nm kwakhiqizwa ku-BBO esike i-Brewster-angle-cut endaweni ezwakalayo ephuma ngaphandle ethuthukisiwe.
I-BBO ingaphinda isetshenziselwe izinhlelo ze-EO. Amaseli e-BBO Pockels noma ama-EO Q-Switches asetshenziselwa ukushintsha isimo sokukhanya esidlula kuso lapho i-voltage isetshenziswa kuma-electrode amakristalu e-electro-optic afana ne-BBO.I-Beta-Barium Borate (i-β-BaB2O4, BBO) enezinhlamvu ezibonisa ukukhanya okubanzi nobubanzi obuhambisana nesigaba, i-coefficient enkulu engaqondile, i-threshold yomonakalo omkhulu kanye ne-homogeneity enhle kakhulu ye-optical kanye nezakhiwo ze-electro-optical zinikeza amathuba okukhangayo ezinhlelo zokusebenza ezihlukahlukene ze-optical nonlinear kanye nezicelo ze-electro-optic.
Izici ze-BBO Crystals:
• Ibanga elibanzi elilinganisekayo ukusuka ku-409.6 nm ukuya ku-3500 nm;
• Isifunda esibanzi sokudlulisa kusuka ku-190 nm kuya ku-3500 nm;
• I-coefficient enkulu ye-second-harmonic-generation (SHG) esebenza ngempumelelo enkulu cishe izikhathi eziyisi-6 kunaleyo yekristalu ye-KDP;
• Umkhawulo womonakalo omkhulu;
• I-homogeneity ephezulu ye-optical nge-δn ≈10-6/cm;
• Amazinga okushisa abanzi-umkhawulokudonsa ongaba ngu-55℃.
Isaziso esibalulekile:
I-BBO inokuthambekela okuphansi kumswakama.Abasebenzisi bayelulekwa ukuthi banikeze izimo ezomile kukho kokubili ukusetshenziswa nokulondolozwa kwe-BBO.
I-BBO ithambile uma kuqhathaniswa ngakho idinga izinyathelo zokuvikela izindawo zayo ezipholishiwe.
Uma ukulungiswa kwe-engeli kudingekile, sicela ukhumbule ukuthi i-engeli yokwamukela ye-BBO incane.
