    I-LBO (Lithium Triborate - LiB3O5) manje isisetshenziswa okuthandwa kakhulu kwe-Second Harmonic Generation (SHG) yamandla kagesi ayi-1064nm (esikhundleni se-KTP) kanye neSum Frequency Generation (SFG) yomthombo we-1064nm laser ukuthola ukukhanya kwe-UV ku-355nm .
    I-LBO iyisigaba esilingana ne-SHG ne-THG ye-Nd: YAG ne-Nd: YLF lasers, kusetshenziswa noma yikuphi ukuhlangana I noma ukuthintana kohlobo II. Okwe-SHG ekamelweni lokushisa, uhlobo lokulinganisa lwesigaba lungafinyelelwa futhi lunokulingana okuphelele okusebenzayo kwe-SHG kuzindiza eziyinhloko ze-XY ne-XZ ebangeni lobubanzi obubanzi ukusuka ku-551nm kuye cishe ku-2600nm. Ukusebenza kahle kokuguqulwa kwe-SHG ngaphezulu kwe-70% ye-pulse ne-30% ye-cw Nd: i-lasers ye-YAG, nokusebenza kahle kokuguqulwa kwe-THG ngaphezulu kwe-60% ye-pulse Nd: i-YAG laser iye yabonwa.
    I-LBO iyi-NLO crystal enhle kakhulu yama-OPO nama-OPAs anebanga lokulinganisa lamandla elisebenza kabanzi namandla amakhulu. La ma-OPO ne-OPA adonswa yi-SHG ne-THG kaNd: YAG laser neXeCl excimer laser e-308nm kubikiwe. Izici ezihlukile zohlobo I nohlobo II oluhambisana nesigaba kanye ne-NCPM zishiya igumbi elikhulu ocwaningweni nasekusetshenzisweni kwe-LBO's OPO ne-OPA.
    Izinzuzo:
    • Ububanzi obusobala busukela ku-160nm kuye ku-2600nm;
    • I-homogeneity ephezulu ye-optical (δn≈10-6 / cm) futhi ayinakho ukufakwa;
    • I-coefficient esebenzayo enkulu kakhulu ye-SHG (cishe kathathu kune-KDP);
    • Umngcele omkhulu wokulimala;
    • I-engela yokwamukela ebanzi nokuhamba okuncane;
    • Thayipha i-I bese uthayipha isigaba sesibili esingacacisi (NCPM) ebangeni lobubanzi obubanzi;
    • I-Spectral NCPM eduze kwase-1300nm.
    Izicelo:
    • Okungaphezulu kokungu-480mW okukhipha ku-395nm kudalwa yimvamisa yokuphinda kabili i-Ti ekhiywe imodi eyi-2W: Sapphire laser (<2ps, 82MHz). Ububanzi bamaza we-700-900nm buhlanganiswe yi-5x3x8mm3 LBO crystal.
    • Ngaphezulu kokukhipha okuluhlaza okungu-80W okutholwa yi-SHG ye-Q-switched Nd: YAG laser ngohlobo II 18mm long LBO crystal.
    • Imvamisa yokuphinda kabili kwediode ekhishwe u-Nd: YLF laser (> 500μJ @ 1047nm, <7ns, 0-10KHz) ifinyelela ngaphezu kuka-40% wokusebenza kahle kokuguqulwa ku-9mm long LBO crystal.
    • Okukhishwayo kwe-VUV ngo-187.7 nm kutholwa ngokwenza isizungezi semvamisa.
    • Ugongolo olulinganiselwe i-2mJ / pulse diffraction-limited ku-355nm lutholwa ngemvamisa ye-intracavity ephindaphindwe kathathu nge-Q-switched Nd: YAG laser.
    • Kutholakale ukusebenza kahle okuphelele okuphelele kokuguquguquka nobubanzi be-wavelength engu-540-1030nm nge-OPO edonswe ku-355nm.
    • Thayipha i-OPA edonswe ku-355nm ngekhono lokuguqulwa kwamandla okupompa isignali elingu-30% selibikiwe.
    • Uhlobo II NCPM OPO olumpompwe nge-XeCl excimer laser e-308nm seluzuze ukusebenza ngokuguqulwa okungu-16.5%, futhi amabanga we-wavevel we-tunable enokulinganiswa angatholakala ngemithombo ehlukene yokupompa nokulungiswa kwamazinga okushisa.
    • Ngokusebenzisa inqubo ye-NCPM, thayipha i-O OPA ekhishwe yi-SHG ye-Nd: YAG laser e-532nm nayo yabonwa ukumboza ibanga elibanzi lokuhleleka kusuka ku-750nm kuya ku-1800nm ​​ngokushuna kokushisa kusuka ku-106.5 .5 kuya ku-148.5 ℃.
    • Ngokusebenzisa uhlobo II NCPM LBO njenge-optical parametric generator (OPG) bese uthayipha i-BBO ehambisana nezigaba ezibucayi njenge-OPA, i-linewidth ewumngcingo (0.15nm) kanye nepompo-to-signal energy conversion (32.7%) etholakele lapho ishaywa yi-4.8mJ, i-30ps laser ku-354.7nm. Ibanga lokushuna le-Wavelength lisuka ku-482.6nm laya ku-415.9nm lambozwa ngokukhuphula izinga lokushisa le-LBO noma ngokushintshanisa i-BBO.
