Amakristalu angaqondile

Izindlela zokukhulisa ezihlanganisa ezivundlile neziqondile, lezi zinsiza(ZnGeP2, AgGaS2, AgGaSe2, GaSe, KTA, KTP, BIBO, LBO, BBO) ziyatholakala ngamasayizi ajwayelekile nezimo.Ezinye zazo, ezinezakhiwo ze-coefficient enkulu engaqondile kanye nobukhulu obuhlukile esikunikezile, zisetshenziswa kabanzi kumasistimu we-SHG, i-THG ne-Mid-infrared OPO,OPA, njll. Imikhiqizo ingalethwa noma ngaphandle kwesibambi se-Aluminium Anodized.

I-Gase Crystal

I-Gallium Selenide (GaSe) i-non-linear optical single crystal, ehlanganisa i-coefficient enkulu engeyona umugqa, umkhawulo womonakalo ophezulu kanye nobubanzi obubanzi bokukhanyela.Kuyinto efanelekile kakhulu ku-SHG maphakathi ne-IR.
Amakristalu e-ZGP(ZnGeP2)

Amakristalu e-ZGP anama-coefficients amakhulu angaqondile (d36=75pm/V), ububanzi be-infrared transparency range (0.75-12μm), izinga eliphezulu le-thermal conductivity (0.35W/(cm·K)), umkhawulo wokulimala kwe-laser (2-5J/cm2) kanye Isakhiwo somshini kahle, ikristalu ye-ZnGeP2 yayibizwa ngokuthi inkosi yamakristalu e-infrared nonlinear optical futhi iseyimpahla yokuguqula imvamisa engcono kakhulu yamandla aphezulu, isizukulwane se-laser ye-infrared esiguqulekayo.Singanikela ngekhwalithi ephezulu yokubona kanye namakristalu amakhulu e-ZGP anodayalo oluncane kakhulu ane-coefficient yokumuncwa ephansi kakhulu engu-α <0.05 cm-1 (kumaza wamaza epompo angu-2.0-2.1 µm), angasetshenziswa ukukhiqiza i-laser eguqulekayo ye-infrared esebenza kahle kakhulu nge-OPO noma i-OPA. izinqubo.
Amakristalu e-AGSe(AgGaSe2).

AGSeAmakristalu e-AgGaSe2 anemiphetho yebhendi ku-0.73 naku-18 µm.Ibanga layo lokudlulisela eliwusizo (0.9–16 µm) nekhono lokufanisa isigaba esibanzi linikeza amandla amahle kakhulu wezinhlelo ze-OPO uma zimpontshwa amalaser ahlukahlukene ahlukahlukene.Ukushuna phakathi kuka-2.5–12 µm kutholwe uma kuphanjwa nge-laser ye-Ho:YLF ku-2.05 µm;kanye nokusebenza okungabalulekile kwesigaba sokufanisa (NCPM) phakathi kuka-1.9–5.5 µm uma iphampu ngo-1.4–1.55 µm.I-AgGaSe2 (AgGaSe2) iboniswe njengekristalu esebenza ngokuphindwe kabili yefrikhwensi ye-infrared CO2 lasers radiation.
Amakristalu e-AGS(AgGaS2).

I-AGS ibonakala ngale ukusuka ku-0.50 kuye ku-13.2 µm.Nakuba i-coefficient yayo ye-optical nonlinear iphansi kakhulu phakathi kwamakristalu e-infrared ashiwo, ukuhlelwa kwe-wavelength emfushane okubonisa ngale ku-550 nm kusetshenziswa kuma-OPO ampontshwa yi-Nd:YAG laser;emihlolweni eminingi yokuhlanganisa imvamisa yomehluko nge-diode, i-Ti:Sapphire, Nd:YAG namalaser kadayi we-IR amboza ububanzi obungu-3–12 µm;kumasistimu okumelana ne-infrared aqondile, kanye ne-SHG ye-CO2 laser.Amapuleti ekristalu e-Thin AgGaS2 (AGS) adumile ekukhiqizeni i-ultrashort pulse ebangeni elimaphakathi le-IR ngomehluko wokukhiqiza imvamisa esebenzisa i-NIR wavelength pulses.
Amakristalu e-BGSe(BaGa4Se7).

Amakristalu ekhwalithi ephezulu e-BGSe (BaGa4Se7) iyi-analogue ye-selenide ye-chalcogenide compound BaGa4S7, isakhiwo sayo se-acentric orthorhombic sahlonzwa ngo-1983 futhi umphumela we-IR NLO wabikwa ngo-2009, iyikristalu esanda kwakhiwa ye-IR NLO.Itholwe ngendlela ye-Bridgman–Stockbarger.Le kristalu ikhombisa ukudluliselwa okuphezulu ebangeni elibanzi le-0.47-18 μm, ngaphandle kwenani eliphakeme lokumunca cishe elingama-15 μm.
Amakristalu e-BGGSe(BaGa2GeSe6).

I-crystal ye-BaGa2GeSe6 inomkhawulo ophezulu wokulimala optical (110 MW/cm2), ububanzi be-spectral transparency range (kusuka ku-0.5 kuya ku-18 μm) kanye nokungaqondile okuphezulu (d11 = 66 ± 15 pm/V) , okwenza le crystal ikhange kakhulu ukuguqulwa kwemvamisa kwemisebe ye-laser ibe (noma ngaphakathi) kwebanga eliphakathi kwe-IR.
