ZnGeP2 - Ib qho Saturated Infrared Nonlinear Optics
Product Description
Vim tias cov khoom tshwj xeeb no, nws yog lub npe hu ua ib qho ntawm cov khoom lag luam zoo tshaj plaws rau cov ntawv siv kho qhov muag uas tsis yog-linear. ZnGeP2 tuaj yeem tsim 3-5 μm nruam tunable laser tawm los ntawm optical parametric oscillation (OPO) thev naus laus zis. Lasers, kev khiav hauj lwm nyob rau hauv lub atmospheric kis qhov rais ntawm 3-5 μm yog ib qho tseem ceeb heev rau ntau yam kev siv, xws li infrared txee ntsuas, tshuaj xyuas, kho mob apparatus, thiab tej thaj chaw deb sensing.
Peb tuaj yeem muab cov khoom siv kho qhov muag zoo ZnGeP2 nrog qhov tsis tshua muaj qhov 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 mid-infrared tunable laser nrog kev ua haujlwm siab los ntawm OPO lossis OPA txheej txheem.
Peb Muaj Peev Xwm
Dynamic Temperature Field Technology tau tsim thiab siv los ua ke ZnGeP2 polycrystalline. Los ntawm cov thev naus laus zis no, ntau tshaj 500g siab purity ZnGeP2 polycrystalline nrog cov nplej loj loj tau raug tsim los hauv ib qho kev khiav.
Kab rov tav Gradient Freeze txoj kev ua ke nrog Directional Necking Technology (uas tuaj yeem txo qhov dislocation ceev tau zoo) tau ua tiav zoo rau kev loj hlob zoo ZnGeP2.
Lub kilogram-theem zoo ZnGeP2 nrog lub ntiaj teb txoj kab uas hla loj tshaj plaws (Φ55 mm) tau ua tiav zoo los ntawm Vertical Gradient Freeze method.
Qhov saum npoo roughness thiab flatness ntawm cov khoom siv siv lead ua, tsawg dua 5Å thiab 1/8λ raws li, tau txais los ntawm peb cov cuab yeej cuab tam zoo.
Qhov kawg ntawm lub kaum sab xis sib txawv ntawm cov khoom siv siv lead ua yog tsawg dua 0.1 degree vim yog siv cov kev taw qhia meej thiab cov txheej txheem txiav.
Cov khoom siv nrog kev ua tau zoo heev tau ua tiav vim qhov zoo ntawm cov khoom siv lead ua thiab cov txheej txheem siv lead ua theem siab (Lub 3-5μm nruab nrab-infrared tunable laser tau tsim nrog kev hloov pauv kev ua haujlwm ntau dua 56% thaum pumped los ntawm 2μm teeb. qhov chaw).
Peb pab pawg tshawb fawb, los ntawm kev tshawb nrhiav txuas ntxiv thiab kev tsim kho tshiab, tau ua tiav cov txheej txheem synthesis ntawm high-purity ZnGeP2 polycrystalline, kev loj hlob technology ntawm loj loj thiab zoo ZnGeP2 thiab siv lead ua orientation thiab high-precision ua technology; tuaj yeem muab ZnGeP2 cov khoom siv thiab cov khoom siv qub uas loj hlob hauv cov nplai loj nrog kev sib txuam siab, tsis tshua muaj kev nqus coefficient, kev ruaj ntseg zoo, thiab kev hloov pauv siab. Nyob rau tib lub sijhawm, peb tau tsim tag nrho cov txheej txheem ntawm kev ntsuas kev ua haujlwm siv lead ua uas ua rau peb muaj peev xwm muab cov kev pabcuam siv lead ua haujlwm rau cov neeg siv khoom.
