I-ZnGeP2-I-Saturated Infrared Nonlinear Optics
Ingcaciso yeMveliso
Ngenxa yezi zakhiwo ezizodwa, iyaziwa njengenye yezona zinto zithembisayo kwizicelo ezingabonakaliyo ezingabonakaliyo. I-ZnGeP2 inokuvelisa i-3-5 μm yelaser eqhubekayo etyhunotywayo ibekwe ngeteknoloji yeparametric oscillation (OPO) yetekhnoloji. I-Lasers, esebenza kwifestile ye-atmospheric transmission ye-3-5 μm ibaluleke kakhulu kwizicelo ezininzi, ezifana ne-infrared counter measure, ukujonga iikhemikhali, izixhobo zonyango, kunye ne-remote sensor.
Singanikezela ngekhwalithi ephezulu ye-Optical ye-ZnGeP2 ene-coefficient yokufunxa ephantsi kakhulu α <0.05 cm-1 (kwimpompo yamaza obude obuyi-2.0-2.1 µm), engasetyenziselwa ukuvelisa i-laser e-mid-infrared esebenza ngokufanelekileyo nge-OPO okanye iinkqubo ze-OPA.
Isakhono sethu
ITekhnoloji yoMmandla woBubushushu obuDynamic yenziwa yaza yasetyenziswa ukudibanisa i-polycrystalline ye-ZnGeP2. Ngale teknoloji, ngaphezulu kwe-500g yococeko oluphezulu lwe-ZnGeP2 i-polycrystalline eneenkozo ezinkulu iye yadityaniswa ngexesha elinye.
Indlela ye-Horizontal Gradient Freeze edityaniswe ne-Directional Necking Technology (enokuthi ithobe ukuxinana kwe-dislocation ngokufanelekileyo) isetyenziswe ngempumelelo ekukhuleni komgangatho ophezulu we-ZnGeP2.
I-ZnGeP2 yomgangatho ophezulu wekhilogram enobukhulu behlabathi (Φ55 mm) ikhuliswe ngempumelelo yi-Vertical Gradient Freeze method.
Uburhabaxa nomphezulu wezixhobo zekristale, ngaphantsi kwe-5Å kunye ne-1/8λ ngokulandelanayo, zifunyenwe ngomgibe wethu wobugcisa bonyango.
Ukuphambuka kwe-angle yokugqibela yezixhobo ze-crystal zingaphantsi kwe-0.1 idigri ngenxa yokusetyenziswa kwe-orientation echanekileyo kunye neendlela zokusika ezichanekileyo.
Izixhobo ezinomsebenzi ogqwesileyo ziye zaphunyezwa ngenxa yomgangatho ophezulu weekristale kunye nomgangatho ophezulu we-crystal processing technology (I-3-5μm mid-infrared laser tunable ilaser iye yaveliswa ngokuguqulwa okusebenzayo okungaphezulu kwe-56% xa impontshwa ngokukhanya kwe-2μm. umthombo).
Iqela lethu lophando, ngokuhlola okuqhubekayo kunye nobugcisa obutsha, liye laphumelela ngempumelelo iteknoloji yokudibanisa ye-polycrystalline ephezulu ye-ZnGeP2, iteknoloji yokukhula yobukhulu obukhulu kunye nomgangatho ophezulu we-ZnGeP2 kunye ne-crystal orientation kunye ne-high-precision processing technology; inokubonelela ngezixhobo ze-ZnGeP2 kunye neekristale zangaphambili njengoko zikhulile kwisikali sobunzima kunye nokufana okuphezulu, i-coefficient ephantsi yokufunxa, ukuzinza okulungileyo, kunye nokusebenza kakuhle kokuguqulwa. Ngelo xesha, siye saseka isethi epheleleyo yeqonga lokuvavanya ukusebenza kwekristale esenza sibe nekhono lokubonelela ngeenkonzo zokuvavanya ukusebenza kwekristale kubathengi.
