    LBO (Lithium Triborate - LiB3O5) tsopano ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri ku Second Harmonic Generation (SHG) cha 1064nm lasers high power (m'malo mwa KTP) ndi Sum Frequency Generation (SFG) ya 1064nm laser source kuti ikwaniritse kuwala kwa UV pa 355nm .
    LBO ndi gawo lofananirana ndi SHG ndi THG ya Nd: YAG ndi Nd: YLF lasers, pogwiritsa ntchito mtundu wina kapena kuyanjana kwachiwiri. Kwa SHG kutentha kwapakati, mtundu wa I gawo lofananira ungafikiridwe ndipo ungakhale woyenerana moyenera ndi SHG mu ndege zazikulu za XY ndi XZ munthawi yotalikirapo kuyambira 551nm mpaka pafupifupi 2600nm. Kuchita bwino kwa SHG kopitilira 70% kwa zimachitika ndi 30% ya cw Nd: YAG lasers, ndi kuthekera kwa kutembenuka kwa THG kupitirira 60% ya pulse Nd: YAG laser yawonedwa.
    LBO ndi NLO crystal yabwino kwambiri ya ma OPO ndi ma OPA omwe ali ndi magwiridwe antchito amphamvu kwambiri komanso mphamvu zazikulu. Izi OPO ndi OPA zomwe zimaponyedwa ndi SHG ndi THG wa Nd: YAG laser ndi XeCl excimer laser ku 308nm adanenedwa. Makhalidwe apadera amtundu wa I ndi mtundu wachiwiri wofananira gawo komanso NCPM imasiya chipinda chachikulu pakufufuza ndikugwiritsa ntchito LBO's OPO ndi OPA.
    Ubwino:
    • Kuwonetsera kwakukulu kuyambira pa 160nm mpaka 2600nm;
    • Homogeneity yapamwamba kwambiri (δn≈10-6 / cm) ndikukhala opanda gawo;
    • Chowerengera chachikulu cha SHG chokwanira (pafupifupi katatu kuposa KDP);
    • Kuwonongeka kwakukulu;
    • Kulandila mbali yayitali ndi kuyenda pang'ono;
    • Lembani I ndikulemba gawo lachiwiri losafunikira (NCPM) mosiyanasiyana;
    • Spectral NCPM pafupi ndi 1300nm.
    Mapulogalamu:
    • Zoposa 480mW zotulutsidwa ku 395nm zimapangidwa ndikuchulukitsa kopitilira muyeso wa 2W wa Ti: Sapphire laser (<2ps, 82MHz). Kutalika kwa kutalika kwa 700-900nm kumaphimbidwa ndi kristalo ya 5x3x8mm3 LBO.
    • Kutulutsa kopitilira 80W kobiriwira kumapezeka ndi SHG wa Q-switched Nd: YAG laser mumtundu wachiwiri wa 18mm LBO crystal.
    • Kuchulukanso kwa diode yopopera Nd: YLF laser (> 500μJ @ 1047nm, <7ns, 0-10KHz) imafikira 40% yotembenuka moyenera mu kristalo wa 9mm wa LBO.
    • Kutulutsa kwa VUV pa 187.7 nm kumapezeka pakupanga kwapafupipafupi.
    • 2mJ / pulse diffraction-limited beam ku 355nm imapezeka mwakachetechete kopitilira muyeso wa Q-switched Nd: YAG laser.
    • Kutembenuka kwakukulu kwathunthu ndi mawonekedwe a 540-1030nm otseguka kutalika kwake adapezeka ndi OPO yopopera pa 355nm.
    • Type I OPA yopopera pa 355nm ndikuwonetsa kutulutsa mphamvu kwa pump-to-signal ya 30%.
    • Mtundu Wachiwiri wa NCPM OPO wopopedwa ndi XeCl excimer laser ku 308nm wakwaniritsa kutembenuka kwa 16.5%, ndipo masanjidwe oyenda bwino a nthawi yayitali amatha kupezeka ndi magwero osiyanasiyana opopera ndi kutentha kwa kutentha.
    Pogwiritsira ntchito njira ya NCPM, lembani I OPA yopopedwa ndi SHG ya Nd: YAG laser ku 532nm idawonekeranso kuti ikwaniritse masanjidwe ambiri kuchokera ku 750nm mpaka 1800nm ​​poyatsira kutentha kuchokera ku 106.5 ℃ mpaka 148.5 ℃.
    Pogwiritsa ntchito mtundu wachiwiri wa NCPM LBO ngati makina opanga ma parametric generator (OPG) ndikuyimira BBO yofananira ndi BBO ngati OPA, mzere wopapatiza (0.15nm) komanso kutulutsa mphamvu zamagetsi (32.7%) zidapezeka ikapopera ndi 4.8mJ, 30ps laser ku 354.7nm. Mawonekedwe a Wavelength kuyambira 482.6nm mpaka 415.9nm adaphimbidwa mwina pakuwonjezera kutentha kwa LBO kapena potembenuza BBO.
