Er, Cr YSGG Muab Cov Khoom Siv Tau Zoo Laser Crystal
Vim muaj ntau yam kev kho mob, dentine hypersensitivity (DH) yog ib qho mob hnyav thiab nyuaj rau kev kho mob. Raws li ib qho kev daws teeb meem, kev siv lasers siab tau raug tshawb fawb. Qhov kev sim tshuaj no tau tsim los tshuaj xyuas cov teebmeem ntawm Er: YAG thiab Er, Cr: YSGG lasers ntawm DH. Nws yog randomized, tswj, thiab ob-dig muag. 28 tus neeg koom hauv pab pawg tshawb fawb txhua tus txaus siab rau qhov yuav tsum tau muaj rau kev suav nrog. Qhov kev xav tau raug ntsuas los ntawm kev siv qhov muag pom kev ntsuas ua ntej kev kho mob raws li cov hauv paus ntsiab lus, tam sim ntawd ua ntej thiab tom qab kev kho mob, nrog rau ib lub lis piam thiab ib hlis tom qab kev kho mob.

AgGaSe2 Crystals - Band Ntug Ntawm 0.73 Thiab 18 µm
AGSe2 AgGaSe2(AgGa(1－x)InxSe2) muaj cov npoo ntawm 0.73 thiab 18 µm. Nws muaj txiaj ntsig sib kis tau ntau yam (0.9-16 µm) thiab dav theem sib txuam muaj peev xwm muab tau zoo heev rau OPO daim ntawv thov thaum siv los ntawm ntau hom lasers sib txawv.

ZnGeP2 - Ib qho Saturated Infrared Nonlinear Optics
Vim muaj cov coefficients loj (d36 = 75pm / V), dav infrared transparency range (0.75-12μm), siab thermal conductivity (0.35W / (cm·K)), siab laser puas pib (2-5J / cm2) thiab zoo machining cuab yeej, ZnGeP2 tau hu ua huab tais ntawm infrared nonlinear optics thiab tseem yog qhov zoo tshaj plaws zaus hloov khoom siv rau lub zog siab, tunable infrared laser tiam.

AgGaS2 - Nonlinear Optical Infrared Crystals
AGS yog pob tshab los ntawm 0.53 mus rau 12 µm. Txawm hais tias nws cov nonlinear optical coefficient yog qhov qis tshaj ntawm cov hais txog infrared crystals, siab luv wavelength transparency edging ntawm 550 nm yog siv los ntawm OPOs pumped los ntawm Nd: YAG laser; nyob rau hauv ntau qhov sib txawv zaus sib xyaw nrog diode, Ti: Sapphire, Nd: YAG thiab IR dye lasers npog 3-12 µm ntau yam; nyob rau hauv ncaj qha infrared countermeasure systems, thiab rau SHG ntawm CO2 laser.
Cov khoom
ZGP (0.7um-12um, High thermal conductivity-35W / MK), AgGaS2 & AgGaSe2 (OPO), Er, Cr: YSGG (2790nm, Feem ntau yog siv rau hauv paus kwj dej kho mob, kab mob hauv lub cev, kab mob, caries, dentin hypersensitivity, pulpotomy, thiab lwm yam)
