Yb: YAG Crystals

Yb: YAG yog ib qho ntawm cov khoom siv laser-active tshaj plaws thiab tsim nyog rau diode-tswj dua li cov kab ke Nd-doped.Piv nrog rau feem ntau siv Nd: YAG crsytal, Yb: YAG siv lead ua muaj qhov nqus dej ntau dua los txo cov kev tswj xyuas thermal rau diode lasers, lub neej ntev dua-laser theem, peb mus rau plaub zaug qis dua thermal loading ib lub twj tso kua mis zog.Yb: YAG siv lead ua yuav tsum hloov Nd:YAG siv lead ua rau lub zog siab diode-twj lasers thiab lwm yam kev siv tau.
Ho: YAG Crystals

Ho: YAG Ho³⁺ions doped rau hauv insulating laser crystals tau nthuav tawm 14 inter-manifold laser raws, kev khiav hauj lwm nyob rau hauv temporal hom los ntawm CW mus rau hom-xauv.Ho:YAG feem ntau yog siv los ua ib qho txiaj ntsig zoo los tsim 2.1-μm laser emission los ntawm⁵I₇-⁵I₈Kev hloov pauv, rau cov ntawv thov xws li laser tej thaj chaw deb sensing, kho mob phais, thiab siv Mid-IR OPO's kom ua tiav 3-5micron emission.Direct diode pumped systems, thiab Tm: Fiber Laser pumped system tau ua kom pom qhov zoo ntawm txoj kab nqes, qee qhov nce mus txog qhov kev txwv.
Tm: YAP Crystals

Tm doped crystals puag ntau yam ntxim nyiam uas xaiv lawv raws li cov khoom xaiv rau cov khoom siv hauv lub xeev laser nrog emission wavelength tunable nyob ib ncig ntawm 2um.Nws tau pom tias Tm:YAG laser tuaj yeem hloov kho los ntawm 1.91 txog 2.15um.Ib yam li ntawd, Tm: YAP laser tuaj yeem kho qhov ntau ntawm 1.85 txog 2.03 um.Lub quasi-peb theem system ntawm Tm: doped crystals yuav tsum tsim nyog siv cov geometry thiab cov cua kub zoo los ntawm cov xov xwm nquag.
Er: YSGG/Er, Cr: YSGG Crystals

Cov ntsiab lus nquag ntawm Erbium doped Yttrium Scandium Gallium Garnet crystals (Er: Y3Sc2Ga3012 lossis Er: YSGG), ib leeg muaju, yog desinged rau diode pumped solid-state lasers radiating nyob rau hauv 3 µm ntau yam.Er: YSGG crystals qhia qhov kev xav ntawm lawv daim ntawv thov nrog rau kev siv dav hauv Er: YAG, Er: GGG thiab Er: YLF crystals.
Er: YAG Crystals

Er: YAG yog ib yam zoo heev 2.94 um laser siv lead ua, dav siv nyob rau hauv laser kho mob thiab lwm yam teb.Er: YAG siv lead ua laser yog cov khoom siv tseem ceeb tshaj plaws ntawm 3nm laser, thiab txoj kab nqes nrog kev ua haujlwm siab, tuaj yeem ua haujlwm ntawm chav sov laser, laser wavelength nyob rau hauv qhov kev txiav txim ntawm tib neeg qhov muag kev nyab xeeb band, thiab lwm yam 2.94 hli Er: YAG laser muaj tau dav siv nyob rau hauv kev kho mob teb phais, daim tawv nqaij kev zoo nkauj, kho hniav.
Er, Cr: Glass/Er, Cr, Yb: Glass

Erbium thiab ytterbium co-doped phosphate iav muaj daim ntawv thov dav vim yog cov khoom zoo heev.Feem ntau, nws yog cov khoom siv iav zoo tshaj plaws rau 1.54μm laser vim nws qhov muag nyab xeeb wavelength ntawm 1540 nm thiab siab kis tau los ntawm huab cua.Nws kuj tseem tsim nyog rau daim ntawv thov kev kho mob uas xav tau kev tiv thaiv qhov muag yuav nyuaj los tswj lossis txo qis lossis cuam tshuam qhov tseem ceeb ntawm kev pom.Tsis ntev los no nws tau siv nyob rau hauv kev sib txuas lus kho qhov muag fiber ntau es tsis txhob EDFA rau nws cov super plus.Muaj kev vam meej hauv daim teb no.
