I-Si Windows-low Density (Ukuminyana Kwayo Kuyingxenye Yezinto Ze-Germanium)

Ukukhanya kuhlakazeka kalula emingceleni yokusanhlamvu ezintweni ze-polycrystalline, ngakho-ke ukusetshenziswa kwe-optical kudinga i-high-purity single-crystal silicon substrates. Ukuguqulwa kwe-silicon eluhlaza ku-high-purity single-crystal substrates kuqala ngezimayini kanye nokunciphisa i-silica ezithandweni zokushisa eziphezulu. Abakhiqizi baqhubeka becwenga futhi bahlanganise i-polysilicon ehlanzekile engu-97% ukuze basuse noma yikuphi okunye ukungcola, futhi ubumsulwa bungafinyelela ku-99.999% noma kangcono.
Imininingwane Yomkhiqizo:
I-silicon (Si) ikristalu eyodwa iyinto engasebenzi ngamakhemikhali enokuqina okuphezulu futhi engancibiliki emanzini. Isebenza kahle ngokudluliswa kokukhanya ebhendini engu-1-7μm, futhi inokudlulisa ukukhanya okuhle kwibhendi ye-infrared ekude engu-300-300μm Performance, okuyisici ezinye izinto ezibonakalayo ze-infrared ezingenaso. Ikristalu eyodwa ye-silicon (Si) ivamise ukusetshenziswa njenge-substrate ye-3-5μm yewindi le-infrared optical eliphakathi kwegagasi nesihlungi sokubona. Ngenxa ye-thermal conductivity enhle kanye nokuminyana okuphansi kwale nto, kuphinde kube yisinqumo esingcono kakhulu sokwenza izibuko ze-laser noma ukulinganisa izinga lokushisa le-infrared namalensi okukhanya kwe-infrared. Izinto ezisetshenziswa ngokujwayelekile, umkhiqizo ungagcotshwa noma ungagcotshwa.
