ZGP(ZnGeP2) Crystals

ZGP crystals 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 khoom, ZnGeP2 siv lead ua tau hu ua huab tais ntawm infrared nonlinear optical crystals thiab tseem yog qhov zoo tshaj plaws zaus hloov khoom siv rau lub zog siab, tunable infrared laser tiam.Peb tuaj yeem muab cov khoom siv kho qhov muag zoo thiab txoj kab uas hla loj ZGP crystals uas tsis tshua muaj kev nqus coefficient α < 0.05 cm-1 (ntawm lub twj tso kua mis wavelengths 2.0-2.1 µm), uas tuaj yeem siv los tsim nruab nrab-infrared tunable laser nrog kev ua haujlwm siab los ntawm OPO lossis OPA txheej txheem.

Zinc Germanium Phosphide(ZGP)Crystals muaj cov coefficients loj (d36 = 75pm / V).PebZGPmuaj qhov dav infrared pob tshab ntau yam (0.75-12μm), kev sib kis tau zoo los ntawm 1.7um.ZGPkuj qhia tau hais tias muaj thermal conductivity (0.35W / (cm·K)), siab laser puas pib (2-5J / cm2) thiab zoo machining khoom.

ZnGeP2 (ZGP) Crystal tau hu ua huab tais ntawm infrared nonlinear optical crystals thiab nws tseem yog qhov zoo tshaj plaws zaus hloov khoom siv rau lub zog siab, tunable infrared laser tiam.DIEN TECH muab kev kho qhov muag zoo thiab txoj kab uas hla lojZGPmuaju nrog tsawg nqus coefficient α <0.03 cm-1 (ntawm lub twj tso kua mis wavelengths 2.0-2.1 µm).Cov khoom no ua rau ZGP siv lead ua siv los tsim nruab nrab-infrared tunable laser nrog kev ua haujlwm siab los ntawm OPO lossis OPA txheej txheem.

DIEN TECH UA muab ob hom ZnGeP2 siv lead ua, C-ZGP thiab YS-ZGP.YS-ZGP qhia qis dua ntawm 2090nm dua li C-ZGP.C-ZGP absoprtion coefficient ntawm 2090nm <0.05cm-1 thaum YS-ZGP absoprtion coefficient ntawm 2090nm <0.02cm-1 .C-ZGP loj hlob los ntawm ntsug meathod thaum YS-ZGP loj hlob los ntawm kab rov tav meathod.Tsis tas li ntawd, YS-ZGP qhia tau hais tias zoo dua homogeneity thiab tso zis efficiency ib yam nkaus.

Daim ntawv thov ntawmZGP:

• Thib ob, thib peb, thiab thib plaub kev sib haum xeeb ntawm CO2-laser.

• Optical parametric tiam nrog twj tso kua mis ntawm lub wavelength ntawm 2.0 µm.

• thib ob harmonic tiam ntawm CO-laser.

• YS-ZGP yog cov khoom siv rau THz ntau ntawm 40.0 µm txog 1000 µm, pumped los ntawm 1um.

• Ntau zaus ntawm kev sib xyaw ua ke ntawm CO2- thiab CO-lasers hluav taws xob thiab lwm yam lasers ua haujlwm hauv thaj tsam crystal transparency.

Kev cai orientations ntawm pebZGP siv lead uamuaj nyob rau ntawm kev thov.
