Gase Crystal

Gallium Selenide (GaSe) yopanda mzere wonyezimira wonyezimira wa kristalo, kuphatikiza coefficient yayikulu yopanda mzere, chiwopsezo chachikulu chowonongeka komanso mawonekedwe owonekera.Ndizinthu zoyenera kwambiri za SHG pakati pa IR.
Makristalo a ZGP(ZnGeP2).

Makhiristo a ZGP okhala ndi ma coefficients akuluakulu osagwirizana (d36 = 75pm/V), mawonekedwe owoneka bwino a infrared (0.75-12μm), matenthedwe apamwamba (0.35W/(cm·K)), malo owonongeka a laser (2-5J/cm2) ndi makina opanga bwino, kristalo wa ZnGeP2 ankatchedwa mfumu ya makristasi opangidwa ndi infrared nonlinear ndipo akadali njira yabwino kwambiri yosinthira pafupipafupi kuti ikhale yamphamvu kwambiri, yopangidwa ndi laser infrared laser.Titha kupereka mawonekedwe apamwamba kwambiri komanso makhiristo akulu a ZGP okhala ndi mayamwidwe otsika kwambiri α <0.05 cm-1 (pampope wavelengths 2.0-2.1 µm), omwe angagwiritsidwe ntchito kupanga laser yapakatikati ya infrared tunable bwino kwambiri kudzera mu OPO kapena OPA. njira.
Makhiristo a AGSe(AgGaSe2).

AGSeMakandulo a AgGaSe2 ali ndi m'mphepete mwa 0.73 ndi 18 µm.Kutumiza kwake kothandiza (0.9–16 µm) ndi kuthekera kofananira ndi gawo lalikulu kumapereka kuthekera kwabwino kwa mapulogalamu a OPO akamapopedwa ndi ma laser osiyanasiyana.Kukonza mkati mwa 2.5–12 µm kwapezedwa popopa ndi laser ya Ho:YLF pa 2.05 µm;komanso ntchito yofananitsa magawo osafunikira (NCPM) mkati mwa 1.9–5.5 µm popopera pa 1.4–1.55 µm.AgGaSe2 (AgGaSe2) yawonetsedwa kuti ndi yothandiza pafupipafupi kuwirikiza kawiri kristalo pama radiation a infrared CO2 lasers.
AGS (AgGaS2) makhiristo

AGS imawonekera kuchokera ku 0.50 mpaka 13.2 µm.Ngakhale kuti coefficient yake ya kuwala kopanda mzere ndi yotsika kwambiri pakati pa makhiristo a infuraredi omwe atchulidwa, mawonekedwe owoneka bwino afupikitsa pa 550 nm amagwiritsidwa ntchito mu OPO omwe amapopedwa ndi Nd:YAG laser;pamitundu yosiyanasiyana yoyesera yosakanikirana ndi diode, Ti:Sapphire, Nd:YAG ndi IR utoto lasers ophimba 3-12 µm osiyanasiyana;m'makina achindunji a infrared countermeasure system, ndi SHG ya CO2 laser.Ma mbale akristalo a Thin AgGaS2 (AGS) ndiwodziwika kwambiri pakupanga ma ultrashort pulse m'katikati mwa IR ndi kusiyana kwafupipafupi komwe kumagwiritsa ntchito ma pulses a NIR wavelength.
Makhiristo a BGSe(BaGa4Se7).

Makristasi apamwamba kwambiri a BGSe (BaGa4Se7) ndi selenide analogue ya chalcogenide compound BaGa4S7, yomwe acentric orthorhombic structure inadziwika mu 1983 ndipo zotsatira za IR NLO zinanenedwa mu 2009, ndi crystal yatsopano ya IR NLO.Idapezedwa kudzera munjira ya Bridgman-Stockbarger.Klastalo iyi imawonetsa kufalikira kwakukulu pamitundu yambiri ya 0.47-18 μm, kupatula pachimake choyamwa pafupifupi 15 μm.
Makhiristo a BGGSe(BaGa2GeSe6).

Makristalo a BaGa2GeSe6 ali ndi mawonekedwe owonongeka kwambiri (110 MW/cm2), mawonekedwe owoneka bwino (kuchokera ku 0.5 mpaka 18 μm) komanso kusagwirizana kwakukulu (d11 = 66 ± 15 pm/V), zomwe zimapangitsa kuti galasilo likhale lokongola kwambiri kutembenuka kwafupipafupi kwa ma radiation a laser kukhala (kapena mkati) pakati pa IR.
