Crystal idafite umurongo

Gukura uburyo burimo horizontal na vertical, ibi bikoresho (ZnGeP2, AgGaS2, AgGaSe2, GaSe, KTA, KTP, BIBO, LBO, BBO) birahari hamwe nubunini busanzwe hamwe nicyerekezo.Bimwe muribi, hamwe nibintu bya coefficient nini idafite umurongo nubunini budasanzwe twatanze bikoreshwa cyane muri SHG isanzwe, THG na Mid-infrared OPO, sisitemu ya OPA, nibindi.

GaSe Crystal

Gallium Selenide (GaSe) idafite umurongo wa optique imwe ya kristu, ihuza coefficente nini itari umurongo, ibyangiritse cyane kandi byaragutse.Nibikoresho bikwiye cyane kuri SHG hagati ya IR.
ZGP (ZnGeP2) Crystal

Kirisiti ya ZGP ifite coefficient nini idafite umurongo (d36 = 75pm / V), intera yagutse ya infragre (0,75-12μm), amashanyarazi menshi (0.35W / (cm · K)), inzitizi zangiza za laser (2-5J / cm2) na gutunganya neza umutungo, ZnGeP2 kristu yiswe umwami wa infragreire idafite umurongo wa optique kandi iracyari ibikoresho byiza byo guhinduranya inshuro nyinshi kubububasha bukomeye, bushobora gukoreshwa na laser laser generation.Turashobora gutanga ubuziranenge bwa optique hamwe na diameter nini ya ZGP kristal hamwe na coefficient yo hasi cyane yo kwinjiza α <0,05 cm-1 (kuri pompe yumurambararo wa pompe 2.0-2.1 µm), ishobora gukoreshwa mugukora lazeri yo hagati ya infrarafarike ikoreshwa neza kandi ikoresheje OPO cyangwa OPA inzira.
AGSe (AgGaSe2) Crystal

AGSeAgasanduku ka AgGaSe2 gafite impande za 0.73 na 18 µm.Ikwirakwizwa ryingirakamaro (0.9-16 µm) hamwe nubushobozi bwagutse bwo guhuza ubushobozi butanga amahirwe meza kubikorwa bya OPO mugihe bivomwe na laseri zitandukanye.Kuringaniza muri 2.5–12 µm byabonetse mugihe cyo kuvoma na Ho: YLF laser kuri 2.05 µm;kimwe nicyiciro kidahuye gihuza (NCPM) ibikorwa muri 1.9-5.5 µm mugihe cyo kuvoma kuri 1.4-1.55 µm.AgGaSe2 (AgGaSe2) yerekanwe ko ari inshuro ebyiri zikoresha kristu ikwirakwiza imirasire ya CO2.
AGS (AgGaS2) kristu

AGS iragaragara kuva 0.50 kugeza 13.2 µm.Nubwo coefficente yayo idafite umurongo ari yo yo hasi cyane muri za kristu zavuzwe haruguru, hejuru ya 550 nm ikoreshwa neza muri OPO yavomwe na Nd: YAG laser;muburyo butandukanye butandukanye bwo kuvanga ubushakashatsi hamwe na diode, Ti: safiro, Nd: YAG na IR irangi ryirangi rifite uburebure bwa 3–12 µm;muri sisitemu itaziguye yo kurwanya ibipimo, no kuri SHG ya CO2 laser.Isahani ntoya ya AgGaS2 (AGS) ikariso ya kirisiti irazwi cyane kubyara ultrashort pulse kubyara hagati ya IR hagati yumurongo utandukanye ukoresha NIR yumurongo wa pulse.
BGSe (BaGa4Se7) Crystal

Kirisiti yo mu rwego rwo hejuru ya BGSe (BaGa4Se7) ni analoge ya selenide ya chalcogenide compound BaGa4S7, imiterere ya acentric orthorhombic yamenyekanye mu 1983 kandi ingaruka za IR NLO zavuzwe muri 2009, ni kristu nshya ya IR NLO.Yabonetse hakoreshejwe tekinike ya Bridgman - Stockbarger.Iyi kristu yerekana kohereza cyane hejuru ya 0.47-18 mkm, usibye impinga yo kwinjirira kuri 15 mm.
BGGSe (BaGa2GeSe6) Crystal

Ikirangantego cya BaGa2GeSe6 gifite igipimo cyinshi cyo kwangirika kwa optique (110 MW / cm2), ubugari bwagutse bwagaragaye (kuva 0.5 kugeza 18 mkm) hamwe no kutagira umurongo muremure (d11 = 66 ± 15 pm / V), bigatuma iyi kristu ishimisha cyane guhinduranya inshuro ya laser imirasire (cyangwa imbere) hagati ya IR.
