    Tawhā Hangarau

    Ko te LBO (Lithium Triborate - LiB3O5) inaianei te mea tino rongonui mo te Whakatupuranga Harmonic Tuarua (SHG) o 1064nm lasers mana teitei (hei whakakapi ki te KTP) me te Sum Frequency Generation (SFG) o te puna laser 1064nm ki te whakatutuki i te rama UV i te 355nm .
    Ko te LBO he waahanga rite mo te SHG me te THG o Nd: YAG me Nd: YLF lasers, ma te whakamahi i te momo I, momo II ranei te taunekeneke.Mo te SHG i te mahana o te rūma, ka taea te eke ki te whakaritenga wahanga momo I me te whai hua nui o te whakarea SHG i roto i nga rererangi matua XY me XZ i roto i te whānuitanga roangaru mai i te 551nm ki te 2600nm.Ko nga kaha o te huringa SHG neke atu i te 70% mo te pupuhi me te 30% mo te cw Nd: YAG lasers, me te THG te pai o te hurihanga i runga i te 60% mo te pulse Nd: YAG laser kua kitea.
    Ko te LBO he karaihe NLO tino pai mo nga OPO me nga OPA me te awhe roangaru whanui me nga mana teitei.Ko enei OPO me OPA e pupuhihia ana e te SHG me te THG o Nd: YAG laser me te XeCl excimer laser i te 308nm kua korerotia.Ko nga ahuatanga ahurei o te momo I me te momo II e rite ana ki te waahanga me te NCPM ka waiho he ruuma nui mo te rangahau me nga tono a te OPO me te OPA a LBO.
    Painga:
    • Te awhe whanui whanui mai i te 160nm ki te 2600nm;
    • He riterite matakite teitei (δn≈10-6/cm) me te kore whakauru;
    • He whakarea SHG whai hua tino nui (e toru nga wa o te KDP);
    • Paepae kino teitei;
    • He koki whakaae whanui me te hikoi iti;
    • Momo I me te momo II te whakaritenga wahanga kore-arohaehae (NCPM) i roto i te awhe roangaru whanui;
    • Spectral NCPM tata ki te 1300nm.
    Nga tono:
    • Neke atu i te 480mW te whakaputanga i te 395nm ka hangaia e te auau rearua i te aratau 2W-rakaa Ti:Sapphire laser (<2ps, 82MHz).Ko te roangaru o te 700-900nm ka hipokina e te karaihe 5x3x8mm3 LBO.
    • Neke atu i te 80W te putanga matomato ka riro mai i te SHG o te Q-whakawhitinga Nd:YAG laser i roto i te momo II 18mm roa LBO tioata.
    • Ko te auau rearua o te diode maminga Nd: YLF taiaho (> 500μJ @ 1047nm, <7ns, 0-10KHz) tae i runga i 40% te pai tahuri i roto i te 9mm roa LBO tioata.
    • Ko te putanga VUV i te 187.7 nm ka riro mai i te whakaputanga-auau.
    • Ko te 2mJ/pulse diffraction-limited kurupae i te 355nm ka whiwhihia e te auau intracavity e toru i te Q-switched Nd:YAG laser.
    • Ko te tino kaha o te hurihanga me te 540-1030nm te awhe roangaru karekau i whiwhi me te OPO i pania ki te 355nm.
    • Momo I OPA kua pupuhihia i te 355nm me te pai o te huringa o te kaha o te papu-ki-tohu o te 30% kua panuitia.
    • Momo II NCPM OPO maminga e te XeCl excimer laser i 308nm kua tutuki 16.5% te pai o te hurihanga, a ka taea te whiwhi i nga awhe roangaru whakaraerae me nga punaa papua rereke me te whakamaarama o te pāmahana.
    • Ma te whakamahi i te tikanga NCPM, ko te momo I OPA e pupuhihia ana e te SHG o te Nd:YAG laser i te 532nm i kitea ano ki te kapi i te whānuitanga whanui mai i te 750nm ki te 1800nm ​​ma te whakamaarama i te pāmahana mai i te 106.5 ℃ ki te 148.5 ℃.
    • Ma te whakamahi i te momo II NCPM LBO hei kaihanga parametric whatu (OPG) me te momo I tino rite te wahanga-whakaritenga BBO hei OPA, he whanui raina whaiti (0.15nm) me te pai o te whakawhiti hiko papu-ki-tohu (32.7%). i te wa e pupuhihia ana e te 4.8mJ, 30ps laser i te 354.7nm.I hipokina te awhe o te roangaru mai i te 482.6nm ki te 415.9nm ma te whakanui ake i te pāmahana o te LBO, ma te huri ranei i te BBO.
