Nonlinear Crystals

Loj hlob txoj hauv kev suav nrog kab rov tav thiab ntsug, cov ntaub ntawv no (ZnGeP2, AgGaS2, AgGaSe2, GaSe, KTA, KTP, BIBO, LBO, BBO) muaj nyob rau hauv qhov ntau thiab tsawg thiab kev taw qhia.Qee qhov, nrog cov khoom ntawm cov coefficient loj loj thiab qhov tshwj xeeb peb muab tau dav siv hauv SHG, THG thiab Mid-infrared OPO, OPA systems, thiab lwm yam. Cov khoom tuaj yeem xa nrog lossis tsis muaj Anodized Aluminium yas dhos.

GaSe Crystal

Gallium Selenide (GaSe) uas tsis yog-linear optical ib leeg siv lead ua, sib txuas cov coefficient loj uas tsis yog-linear, muaj kev puas tsuaj loj thiab ntau qhov pom tseeb.Nws yog ib qho khoom siv zoo heev rau SHG hauv nruab nrab IR.
ZGP(ZnGeP2) Crystals

ZGP crystals muaj cov coefficients loj (d36 = 75pm / V), dav infrared transparency range (0.75-12μm), siab thermal conductivity (0.35W / (cm·K)), siab laser puas pib (2-5J / cm2) thiab zoo machining khoom, ZnGeP2 siv lead ua tau hu ua huab tais ntawm infrared nonlinear optical crystals thiab tseem yog qhov zoo tshaj plaws zaus hloov khoom siv rau lub zog siab, tunable infrared laser tiam.Peb tuaj yeem muab cov khoom siv kho qhov muag zoo thiab txoj kab uas hla loj ZGP crystals uas tsis tshua muaj kev nqus coefficient α < 0.05 cm-1 (ntawm lub twj tso kua mis wavelengths 2.0-2.1 µm), uas tuaj yeem siv los tsim nruab nrab-infrared tunable laser nrog kev ua haujlwm siab los ntawm OPO lossis OPA txheej txheem.
AGSe(AgGaSe2) Crystals

AGSEAgGaSe2 crystals muaj cov npoo ntawm 0.73 thiab 18 µm.Nws muaj txiaj ntsig sib kis tau ntau yam (0.9-16 µm) thiab dav theem sib txuam muaj peev xwm muab tau zoo heev rau OPO daim ntawv thov thaum siv los ntawm ntau hom lasers sib txawv.Tuning nyob rau hauv 2.5-12 µm tau txais thaum siv los ntawm Ho:YLF laser ntawm 2.05 µm;as well as non-critical phase matching (NCPM) ua hauj lwm nyob rau hauv 1.9–5.5 µm thaum tso tawm ntawm 1.4–1.55 µm.AgGaSe2 (AgGaSe2) tau pom tias yog ib qho kev siv hluav taws xob muaj txiaj ntsig ob npaug rau infrared CO2 lasers hluav taws xob.
AGS (AgGaS2) crystals

AGS yog pob tshab los ntawm 0.50 mus rau 13.2 µm.Txawm hais tias nws cov nonlinear optical coefficient yog qhov qis tshaj ntawm cov hais txog infrared muaju, siab luv wavelength transparency edging ntawm 550 nm yog siv los ntawm OPOs pumped los ntawm Nd: YAG laser;nyob rau hauv ntau qhov sib txawv zaus sib xyaw nrog diode, Ti: Sapphire, Nd: YAG thiab IR dye lasers npog 3-12 µm ntau yam;nyob rau hauv ncaj qha infrared countermeasure systems, thiab rau SHG ntawm CO2 laser.Nyias AgGaS2 (AGS) siv lead ua daim hlau yog nrov rau ultrashort mem tes tiam nyob rau hauv nruab nrab IR ntau yam los ntawm qhov sib txawv zaus tiam siv NIR wavelength pulses.
BGSe(BaGa4Se7) Crystals

Cov muaju zoo ntawm BGSe (BaGa4Se7) yog cov selenide analogue ntawm chalcogenide compound BaGa4S7, uas nws cov qauv acentric orthorhombic tau txheeb xyuas hauv xyoo 1983 thiab IR NLO cov nyhuv tau tshaj tawm xyoo 2009, yog ib qho tshiab tsim IR NLO siv lead ua.Nws tau txais los ntawm cov txheej txheem Bridgman-Stockbarger.Cov khoom siv lead ua no nthuav tawm cov kev xa tawm siab tshaj qhov dav ntawm 0.47-18 μm, tshwj tsis yog rau qhov siab tshaj plaws ntawm 15 μm.
BGGSe(BaGa2GeSe6) Crystals

Lub BaGa2GeSe6 siv lead ua muaj qhov ua kom pom kev puas tsuaj siab (110 MW / cm2), dav spectral transparency ntau yam (los ntawm 0.5 txog 18 μm) thiab siab nonlinearity (d11 = 66 ± 15 pm / V), uas ua rau cov siv lead ua no ntxim nyiam heev rau zaus hloov dua siab tshiab ntawm laser hluav taws xob mus rau hauv (los yog nyob rau hauv) nruab nrab-IR ntau.
