    Gallium Selenide (GaSe) non-linear optical tib siv lead ua, sib txuas nrog cov khoom loj tsis-txoj kab hluav taws xob, qhov ntsuas kev puas tsuaj siab thiab ntau qhov kev pom zoo. Nws yog cov khoom siv tau haum rau SHG hauv nruab nrab-IR. Cov kev hloov pauv zaus-ob npaug ntawm GaSe tau kawm txog qhov ntev ntawm 6.0 andm thiab 12.0 µm. GaSe tau ua tiav zoo rau kev siv tau txiaj ntsig SHG ntawm CO2 laser (txog 9% hloov dua siab tshiab); rau SHG ntawm pulsed CO, CO2 thiab tshuaj DF-laser (l = 2.36 µm) hluav taws xob; kev hloov pauv ntawm CO thiab CO2 laser hluav taws xob rau qhov pom ntau yam; infrared pulses tiam ntawm qhov sib txawv zaus sib xyaw ua ke ntawm Neodymium thiab infrared zas laser lossis (F -) - nruab nrab laser laser pulses; OPG lub teeb tsim nyob rau hauv 3.5–18 ;m; terahertz (T-rays) hluav taws xob tiam. Nws yog impossibile rau kev txiav cov hnub ci rau qee ntu theem sib txuam nrog cov ces kaum vim tias cov khoom qauv qauv (npuaj nrog (001) dav hlau) txwv qhov chaw ntawm cov ntawv thov.
    GaSe yog muag heev thiab fawm kib siv lead ua. Rau zus tau tej cov siv lead ua nrog cov tuab teev peb coj thicker pib dawb paug, Piv txwv li, 1-2 hli tuab thiab ces pib tshem tawm txheej los ntawm txheej sim mus kom ze rau kom kom tuab thaum lub sij hawm ua zoo nto du thiab tiaj. Txawm li cas los xij, rau cov thicknesses txog 0.2-0.3 hli lossis tsawg dua GaSe phaj yooj yim khoov thiab peb tau txais cov kab nkhaus kom tsis txhob tiaj tiaj.
    Yog li peb feem ntau nyob ntawm 0.2 hli tuab rau 10x10 hli siv lead ua mounted hauv hauv dia.1 '' nrog nrog CA qhib dia. 9-9.5 hli.
    Qee lub sij hawm peb lees txais kev txiav txim rau 0.1 hli iav ci, txawm li cas los xij, peb tsis tau lees tias zoo flatness rau thiaj li cov nyias muaju
    Daim ntaub ntawv:
    • Tiam (T-rays) hluav taws xob tua cim ;
    • THz khwv: 0.1-4 THz ;
    • Npaum SHG ntawm CO 2 laser (txog 9% hloov dua siab tshiab);
    • Rau SHG ntawm pulsed CO, CO2 thiab tshuaj DF-laser (l = 2.36 mkm) hluav taws xob;
    • Kev hloov kho ntawm CO thiab CO2 teeb ci rau hauv qhov pom; infrared pulses tiam ntawm qhov sib txawv zaus sib xyaw ua ke ntawm Neodymium thiab infrared zas laser lossis (F -) - nruab nrab laser laser pulses;
    • OPG lub teeb tsim tawm ntev li 3.5 - 18 mkm.
    SHG hauv nruab nrab IR (CO2, CO, tshuaj lom neeg DF-laser thiab lwm yam)
    kev hloov pauv ntawm IR laser hluav taws xob mus rau qhov pom ntau
    Parametric tiam tsis pub dhau 3 - 20 .m
    Terahertz THz tiam (Del Mar Photonics muab ntau yam khoom muaju rau THz tiam, suav nrog ZnTe, GaP, LiNbO3 thiab lwm tus)
    Cov Khoom Tseem Ceeb:
    Muaj kev ua tau ntau yam, ntau dua .6m 0.62 - 20
