    • High optical homogeneity (δn≈10-6/cm) thiab tsis suav nrog;
    • Muaj txiaj ntsig zoo SHG coefficient (li peb npaug ntawm KDP);
    • Muaj kev puas tsuaj loj;
    • Lub kaum sab xis txais dav thiab me me taug kev;
    • Hom I thiab hom II tsis tseem ceeb theem sib txuam (NCPM) nyob rau hauv qhov dav wavelength ntau yam;
    • Spectral NCPM nyob ze 1300nm.
    Daim ntawv thov:
    • Ntau tshaj 480mW tso zis ntawm 395nm yog tsim los ntawm zaus ob npaug ntawm 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 ntsuab tso zis yog tau los ntawm SHG ntawm Q-hloov Nd:YAG laser nyob rau hauv hom II 18mm ntev LBO siv lead ua.
    • Qhov zaus ob npaug ntawm lub diode pumped Nd: YLF laser (> 500μJ @ 1047nm, <7ns, 0-10KHz) ncav cuag tshaj 40% kev hloov pauv kev ua haujlwm hauv 9 hli ntev LBO siv lead ua.
    • Lub VUV tso zis ntawm 187.7 nm yog tau los ntawm sum-frequency tiam.
    • 2mJ/pulse diffraction-limited beam ntawm 355nm yog tau los ntawm intracavity zaus tripling Q-hloov Nd:YAG laser.
    • Ib qho kev hloov pauv tag nrho siab heev thiab 540-1030nm tunable wavelength ntau yam tau txais nrog OPO pumped ntawm 355nm.
    • Hom I OPA pumped ntawm 355nm nrog lub twj tso kua mis-rau-siv lub zog conversion efficiency ntawm 30% tau tshaj tawm.
    • Hom II NCPM OPO pumped los ntawm ib tug XeCl excimer laser ntawm 308nm tau tiav 16.5% conversion efficiency, thiab nruab nrab tunable wavelength ranges yuav tau nrog sib txawv qhov chaw thiab kub tuning.
    • Los ntawm kev siv cov txheej txheem NCPM, hom I OPA pumped los ntawm SHG ntawm ib Nd:YAG laser ntawm 532nm kuj tau pom los npog qhov dav tunable ntau yam ntawm 750nm txog 1800nm ​​los ntawm kev ntsuas kub ntawm 106.5 ℃ txog 148.5 ℃.
    • Los ntawm kev siv hom II NCPM LBO ua qhov kho qhov muag parametric generator (OPG) thiab hom I tseem ceeb theem-matched BBO ua OPA, nqaim linewidth (0.15nm) thiab siab twj tso kua mis-rau-sib nqus zog conversion efficiency (32.7%) tau txais Thaum nws tau txais los ntawm 4.8mJ, 30ps laser ntawm 354.7nm.Wavelength tuning range ntawm 482.6nm txog 415.9nm tau them los ntawm kev nce qhov kub ntawm LBO lossis los ntawm kev tig BBO.
