    Xuduudaha farsamada

    LBO (Lithium Triborate - LiB3O5) hadda waa shayga ugu caansan ee loo isticmaalo Second Harmonic Generation (SHG) ee leysarka awoodda sare leh ee 1064nm (bedel ahaan KTP) iyo Sum Frequency Generation (SFG) ee isha laser 1064nm si loo gaaro nalka UV at 355nm .
    LBO waa wajiga isweydaarsiga SHG iyo THG ee Nd: YAG iyo Nd: YLF lasers, iyadoo la adeegsanayo nooca I ama nooca II isdhexgalka. SHG-da heerkulka qolka, nooca I wajiga u dhigma waa la gaari karaa oo wuxuu leeyahay isku dheelitirnaanta SHG ee ugu badan ee wax ku ool ah diyaaradaha 'XY' iyo 'XZ' oo ku jira baaxad dherer ballaaran oo dhererkeedu yahay 551nm illaa 2600nm Waxtarka beddelka SHG oo ka badan 70% garaaca wadnaha iyo 30% loogu talagalay cw Nd: YAG lasers, iyo THG waxtarka beddelka 60% ee garaaca wadnaha Nd: laser YAG ayaa la arkay.
    LBO waa muraayad aad u fiican oo loo yaqaan 'NLO' oo loo yaqaan 'OPOs' iyo 'OPAs' oo leh baaxad dherer ballaadhan oo ballaadhan iyo awoodo sare OPO iyo OPA kuwaas oo ay soo saarayaan SHG iyo THG ee Nd: YAG laser iyo XeCl laser excimer laser oo gaaraya 308nm ayaa la soo sheegay. Waxyaabaha gaarka u ah nooca I iyo nooca II wajiga u dhigma iyo sidoo kale NCPM waxay ka tagayaan qol weyn oo ku saabsan baaritaanka iyo codsiyada LBO OPO iyo OPA.
    Faa'iidooyinka:
    • Hufnaan ballaadhan oo u dhexeysa 160nm ilaa 2600nm;

    • Xadka ugu sarreeya ee burburka;
    • Xagasha aqbalaad ballaadhan iyo socod-yar;
    • Nooca I iyo nooca II ee iswaafajinta wejiga aan muhiimka ahayn (NCPM) ee baaxadda dherer ballaadhan;
    • Spectral NCPM oo u dhow 1300nm.
    Codsiyada:
    • In ka badan 480mW wax soo saar 395nm ah ayaa laga soo saaraa inta jeer ee labanlaabma a 2W hab-qufulan Ti: Sapphire laser (<2ps, 82MHz). Baaxadda dhererka dhererkiisu yahay 700-900nm waxaa daboolaya a 5x3x8mm3 LBO crystal.
    • In ka badan 80W soosaarka cagaaran waxaa helay SHG oo ah Q-beddelay Nd: YAG laser oo ah nooca II 18mm dherer dhererkiisu yahay LBO.
    • Laablaabnaanta laba-laabka diode-ka la soo tuuray Nd: YLF laser (> 500μJ @ 1047nm, <7ns, 0-10KHz) wuxuu gaarayaa in ka badan 40% wax-ku-beddelashada 9mm dheer oo LBO ah.
    • Soosaarka VUV ee 187.7 nm waxaa lagu helay jiil wadar soo saaris ah.
    • 2mJ / garaaca garaaca wadnaha ku-xaddidan ee 355nm waxaa lagu helaa iyadoo la adeegsanayo qulqulka soo noqnoqodka ah ee Q-daalanaya Nd: YAG laser.
    • Waxtarka guud ee beddelka guud ee sarreeya iyo 540-1030nm baaxadda dherarka dhererka la waafajin karo ayaa lagu helay OPO lagu tuuray 355nm.
    • Nooca I OPA ee lagu soo shubay 355nm oo leh waxsoosaarka tamarta beddelka tamarta ee 30% ayaa la soo sheegay.
    • Nooca II NCPM OPO ee lagu tuuray laser XeCl excimer laser oo ah 308nm wuxuu gaadhay 16.5% hufnaan beddelid, iyo heerar kala dherer dherer dhexdhexaad ah ayaa laga heli karaa ilo bambooyin kala duwan iyo habeynta heerkulka.
    • Adoo adeegsanaya farsamada NCPM, nooca I OPA ee ay soo shubeen SHG ee a Nd: YAG laser at 532nm ayaa sidoo kale la arkay si loo daboolo baaxad ballaaran oo la jaanqaadi karo laga bilaabo 750nm ilaa 1800nm ​​iyadoo lagu hagaajinayo heerkulka 106.5 ℃ ilaa 148.5 ℃.
    • Adoo adeegsanaya nooca II NCPM LBO oo ah matoor koronto dhaliye (OPG) iyo nooca I muhiim ah oo la jaan qaadaya BBO sida OPA, xariiq fidsan oo cidhiidhi ah (0.15nm) iyo karti sare oo bamka-ilaa-calaamadda tamarta beddelidda (32.7%) ayaa la helay. markii uu soo ridayo 4.8mJ, 30ps laser oo ah 354.7nm. Xaddiga Mowjadaha kaladuwan ee u dhexeeya 482.6nm ilaa 415.9nm ayaa lagu daboolay iyadoo la kordhinayo heerkulka LBO ama wareejinta BBO.
