ZnGeP2 - Mawotchi Opanda Mawonekedwe Odzaza ndi Infrared
Mafotokozedwe Akatundu
Chifukwa cha zinthu zapaderazi, zimadziwika kuti ndi imodzi mwazinthu zodalirika kwambiri zopangira ma optical osagwirizana. ZnGeP2 imatha kupanga 3-5 μm laser yosinthika yosalekeza kudzera muukadaulo wa optical parametric oscillation (OPO). Ma laser, omwe amagwira ntchito pawindo la mpweya wa 3-5 μm ndi wofunikira kwambiri pazogwiritsa ntchito zambiri, monga muyeso wa infrared counter, kuyang'anira mankhwala, zida zamankhwala, ndi zowonera kutali.
Titha kupereka ZnGeP2 yapamwamba kwambiri yokhala ndi mayamwidwe otsika kwambiri α <0.05 cm-1 (pampope wavelengths 2.0-2.1 µm), yomwe ingagwiritsidwe ntchito kupanga laser yapakatikati ya infrared tunable yogwira bwino kwambiri kudzera munjira za OPO kapena OPA.
Mphamvu Zathu
Dynamic Temperature Field Technology idapangidwa ndikuyikidwa kuti ipange ZnGeP2 polycrystalline. Kupyolera mu ukadaulo uwu, kupitilira 500g kuyeretsedwa kwakukulu kwa ZnGeP2 polycrystalline yokhala ndi njere zazikulu zapangidwa nthawi imodzi.
Njira ya Horizontal Gradient Freeze kuphatikiza ndi Directional Necking Technology (yomwe ingachepetse kusasunthika bwino) yagwiritsidwa ntchito bwino pakukula kwa ZnGeP2 yapamwamba kwambiri.
ZnGeP2 yapamwamba kwambiri padziko lonse lapansi (Φ55 mm) yakula bwino kwambiri pogwiritsa ntchito njira ya Vertical Gradient Freeze.
Kukula kwamphamvu komanso kusalala kwa zida za kristalo, zosakwana 5Å ndi 1/8λ motsatana, zapezedwa ndi ukadaulo wathu wamankhwala apamwamba.
Kupatuka komaliza kwa zida za kristalo ndi zosakwana digirii 0.1 chifukwa chogwiritsa ntchito njira yolunjika komanso njira zodulira.
Zipangizo zomwe zimagwira ntchito bwino zatheka chifukwa cha luso lapamwamba la makhiristo ndi ukadaulo wapamwamba kwambiri wopangira ma kristalo (The 3-5μm mid-infrared tunable laser yapangidwa ndi kutembenuka kopambana kuposa 56% ikapopedwa ndi kuwala kwa 2μm. gwero).
Gulu lathu lofufuza, kudzera mu kufufuza kosalekeza ndi luso lamakono, lakwanitsa luso la kaphatikizidwe ka polycrystalline yapamwamba kwambiri ya ZnGeP2, teknoloji ya kukula kwa kukula kwakukulu ndi ZnGeP2 yapamwamba kwambiri ndi kristalo ndi luso lapamwamba lokonzekera; imatha kupereka zida za ZnGeP2 ndi makhiristo okulirapo pamlingo wokulirapo wofanana kwambiri, kuyamwa kocheperako, kukhazikika kwabwino, komanso kusinthika kwakukulu. Panthawi imodzimodziyo, takhazikitsa gulu lonse la crystal performance test platform yomwe imatipangitsa kukhala ndi mwayi wopereka ntchito zoyesa kristalo kwa makasitomala.
Mapulogalamu
● Mbadwo wachiwiri, wachitatu, ndi wachinayi wa harmonic wa CO2-laser
● Kupanga zopangira zowoneka bwino zokhala ndi kupopera pamtunda wa 2.0 µm
● Mbadwo wachiwiri wa harmonic wa CO-laser
● Kutulutsa ma radiation ogwirizana mu submillimeterrange kuchokera ku 70.0 µm mpaka 1000 µm
● Kupanga kwa ma frequency ophatikizika a CO2- ndi CO-laser radiation ndi ma laser ena akugwira ntchito m'chigawo cha crystal transparency.
