    Kev tsis

    LBO (Lithium Triborate - LiB3O5) yog tam sim no cov khoom siv nrov tshaj plaws rau Thib Ob Harmonic Tiam (SHG) ntawm 1064nm siab zog lasers (raws li hloov rau KTP) thiab Sum Frequency Generation (SFG) ntawm 1064nm laser qhov dej kom tau UV teeb ntawm 355nm Cov.
    LBO yog theem sib raug rau SHG thiab THG ntawm Nd: YAG thiab Nd: YLF lasers, siv hom I lossis hom II sib cuam tshuam. Rau SHG ntawm chav tsev kub, hom kev sib txuam theem kuv yuav ncav cuag thiab muaj qhov siab tshaj plaws SHG coefficient hauv tus thawj tswj hwm XY thiab XZ dav hlau hauv qhov dav dav ntawm 551nm txog 2600nm. Kev hloov pauv ntawm SHG ua tau zoo tshaj li ntawm 70% rau mem tes thiab 30% rau cw Nd: YAG lasers, thiab THG hloov dua siab tshiab ntau dua 60% rau mem tes Nd: YAG laser tau pom.
    LBO yog qhov zoo tshaj plaws NLO siv lead ua rau OPOs thiab OPAs nrog qhov kev siv dav txav mus los ntawm lub teeb thiab cov muaj zog. Cov OPO thiab OPA uas tau nqus los ntawm SHG thiab THG ntawm Nd: YAG laser thiab XeCl excimer laser ntawm 308nm tau tshaj tawm. Cov yam ntxwv ntawm hom I thiab hom II ua ntu zus raws li NCPM tawm hauv chav loj hauv cov kev tshawb fawb thiab kev siv ntawm LBO's OPO thiab OPA.
    Qhov zoo:
    • Cov pob tshab kis dav dav los ntawm 160nm txog 2600nm;
    • High homogeneity kho qhov muag siab (δn≈10-6 / cm) thiab tsis suav nrog;
    • Kev sib raug zoo ntawm SHG coefficient (ntau txog peb zaug ntawm KDP);
    • Muaj kev piam sij ntau heev;
    • Kev txais lub kaum ntse ntse thiab taug kev me;
    • Hom I thiab hom II tsis tseem ceeb rau kev sib tw theem (NCPM) nyob rau hauv qhov dav dav;
    • Spectral NCPM ze 1300nm.
    Daim ntaub ntawv:
    • Ntau dua 480mW tso tawm ntawm 395nm yog tsim los ntawm kev ua ntau zaus 2W hom-xauv Ti: Sapphire laser (<2ps, 82MHz). Lub wavelength ntau ntawm 700-900nm yog them los ntawm 5x3x8mm3 LBO siv lead ua.
    • Tshaj 80W tso zis ntsuab tau txais los ntawm SHG ntawm Q-hloov pob Nd: YAG laser hauv ib hom II 18mm ntev LBO siv lead ua.
    • Zaus ob zaug ntawm ib qho diode pumped Nd: YLF laser (> 500μJ @ 1047nm, <7ns, 0-10KHz) nce mus txog 40% kev hloov dua siab tshiab hauv kev ua haujlwm 9mm ntev LBO siv lead ua.
    • Cov VUV tawm ntawm 187.7 nm tau txais los ntawm sum-zaus tiam.
    • 2mJ / mem tes diffraction-txwv nqaj ntawm 355nm tau txais los ntawm kev nqus zaus ntau zaus Q-hloov Nd: YAG laser.
    • Ib qho kev hloov pauv ntau heev thiab 540-1030nm tunable wavelength ntau tau los nrog OPO pumped ntawm 355nm.
    • Hom I OPA tso rau ntawm 355nm nrog lub twj tso kua mis-kom-lub zog hloov ua kom zoo zog ntawm 30% tau tshaj tawm.
    • Hom II NCPM OPO pumped los ntawm XeCl excimer laser ntawm 308nm tau tiav 16.5% kev hloov dua siab tshiab, thiab qhov nruab nrab nthwv dej wavelength muaj peev xwm muab tau nrog ntau cov peev xwm tso tawm thiab ntsuas kub.
    • Los ntawm kev siv cov txheej txheem NCPM, hom I OPA tso lub zog los ntawm SHG ntawm ib qho Nd: YAG laser ntawm 532nm kuj tau pom los npog qhov dav ntau yam ntawm 750nm txog 1800nm ​​los ntawm kev ntsuas kub los ntawm 106.5 ℃ txog 148.5 ℃.
    • Los ntawm kev siv hom II NCPM LBO ua lub tshuab ntsuas hluav taws xob (OPG) thiab hom I tseem ceeb rau qib BBO ua OPA, txoj kab nqaim nqaim (0.15nm) thiab lub twj tso kua mis siab-kom lub zog hloov pauv kev ua haujlwm (32.7%) tau los thaum nws nqus los ntawm 4.8mJ, 30ps laser ntawm 354.7nm. Wavelength qhov thaj tsam li ntawm 482.6nm txog 415.9nm tau them rau los ntawm qhov ntsuas kub ntawm LBO lossis los ntawm kev hloov BBO.
