Iikristale ezingezizo

Iindlela zokukhula ezibandakanya ezithe tye kunye nezithe nkqo, ezi zixhobo (ZnGeP2, AgGaS2, AgGaSe2, GaSe, KTA, KTP, BIBO, LBO, BBO) ziyafumaneka ngobungakanani obunikiweyo obuqhelekileyo kunye nokuqhelaniswa.Ezinye zazo, ezineepropati ze-coefficient enkulu engabonakaliyo kunye nemilinganiselo ekhethekileyo esiyinikezile isetyenziswa ngokubanzi kwi-SHG eqhelekileyo, i-THG kunye ne-Mid-infrared OPO, iinkqubo ze-OPA, njl.

Ikristale yeGase

I-Gallium Selenide (i-GaSe) i-crystal e-optical single engabonakaliyo, idibanisa i-coefficient enkulu engekho-linear, i-threshold ephezulu yomonakalo kunye noluhlu olubanzi lokungafihli.Yimathiriyeli efanelekileyo kakhulu ye-SHG embindini we-IR.
Iikristale ze-ZGP(ZnGeP2).

Iikristale ze-ZGP ezinee-coefficients ezinkulu ezingezizo (d36=75pm/V), uluhlu olubanzi lwe-infrared transparency (0.75-12μm), ukuhanjiswa kwe-thermal ephezulu (0.35W/(cm·K)), umda womonakalo welaser (2-5J/cm2) kunye Ipropathi yomatshini wokwenza kakuhle, ikristale ye-ZnGeP2 yayibizwa ngokuba yinkosi yeekristale ze-infrared nonlinear optical kwaye iseyeyona nto ilungileyo yokuguqula i-frequency kumandla aphezulu, ukuveliswa kwe-laser ye-infrared.Singanikezela ngekhwalithi ephezulu yokukhanya kunye nedayamitha enkulu yekristali ye-ZGP ene-coefficient yokufunxa ephantsi kakhulu α <0.05 cm-1 (kwimpompo yamaza obude obuyi-2.0-2.1 µm), enokusetyenziswa ukuvelisa i-laser ephakathi kwe-infrared enokusetyenzwa ngempumelelo ephezulu nge-OPO okanye i-OPA. iinkqubo.
IiCrystals ze-AGSe(AgGaSe2).

AGSeIikristale ze-AgGaSe2 zinemiphetho yebhendi kwi-0.73 kunye ne-18 µm.Uluhlu losasazo oluluncedo (0.9–16 µm) kunye nesigaba esibanzi sokukwazi ukuhambelana kubonelela ngesakhono esibalaseleyo sosetyenziso lwe-OPO xa impontshwa ziintlobo ngeentlobo zeelaser ezahlukeneyo.I-Tuning ngaphakathi kwe-2.5–12 µm ifunyenwe xa ukumpompelwa nge-laser ye-Ho:YLF kwi-2.05 µm;ngokunjalo nokusebenza kwesigaba esingabalulekanga (NCPM) ngaphakathi kwe-1.9–5.5 µm xa umpompa nge-1.4–1.55 µm.I-AgGaSe2 (i-AgGaSe2) ibonakaliswe njengeyona ndlela isebenzayo yokuphinda-phinda ikristale yemitha ye-infrared CO2 lasers.
AGS(AgGaS2) iikristale

I-AGS ibonakalisa elubala ukusuka kwi-0.50 ukuya kwi-13.2 µm.Nangona i-coefficient yayo ye-optical nonlinear iyeyona iphantsi phakathi kweekristale ze-infrared ezikhankanyiweyo, i-wavelength ecacileyo yokukhanya kwe-edging kwi-550 nm isetyenziswe kwii-OPO ezimpontshwa yi-Nd: YAG laser;kwimifuniselo emininzi yokudityaniswa okuphindaphindiweyo ngediode, iTi:Sapphire, Nd:YAG kunye neIR yelaser yedayi egubungela uluhlu lwe-3-12 µm;kwiinkqubo ezithe ngqo ze-infrared countermeasure, kunye ne-SHG ye-CO2 laser.Iipleyiti zekristale eziNcinci ze-AgGaS2 (AGS) zithandwa kakhulu kwi-ultrashort pulse ephakathi kuluhlu lwe-IR ngokwahlukana kwesizukulwana esisebenzisa i-NIR wavelength pulses.
Iikristale ze-BGSe(BaGa4Se7).

Iikristale ezikumgangatho ophezulu we-BGSe (BaGa4Se7) yi-analogue ye-selenide ye-chalcogenide compound BaGa4S7, isakhiwo sayo se-orthorhombic se-acentric ichongiwe kwi-1983 kwaye umphumo we-IR NLO wabikwa kwi-2009, i-crystal ye-IR NLO esanda kuphuhliswa.Yafunyanwa ngobuchule beBridgman–Stockbarger.Le kristale ibonisa ukuhanjiswa okuphezulu kuluhlu olubanzi lwe-0.47-18 μm, ngaphandle kwencopho yokufunxa malunga ne-15 μm.
BGGSe(BaGa2GeSe6) Iikristale

I-crystal ye-BaGa2GeSe6 inomngcipheko ophezulu wokulimala optical (110 MW / cm2), uluhlu olubanzi lwe-spectral transparency (ukusuka kwi-0.5 ukuya kwi-18 μm) kunye nokungahambelani okuphezulu (d11 = 66 ± 15 pm / V), okwenza le crystal ibe nomtsalane kakhulu. ukuguqulwa okuphindaphindiweyo kwemitha yelaser ibe (okanye ngaphakathi) kuluhlu lwe-IR ephakathi.
