Laser - dhuav tsis tau kev puas tsuaj spectroscopy (lais Thaum ND: YAG lasers tau ua haujlwm ua haujlwm rau libs,Erbium - doped iav (ER: iav) lasers, kev khiav hauj lwm ntawm tus yam ntxwv yoj ntawm 2.94 μm, muab cov cim tshwj xeeb rau kev tshuaj xyuas hom qauv.

1. Pib

1.1 lobs thev naus laus zis txheej txheem
Laser - dhuav tsis tau spectroscopy (latiber Lub teeb pom kev los ntawm cov ntshav ntshav txias yog sau thiab raug daws teeb meem rau kev txiav txim siab cov qauv ntawm cov qauv. Its strengths lie in its speed, minimal-to-no sample preparation, ability to perform stand-off analysis, and capacity for simultaneous multi-element detection. Kev lig kev cai, ND: YAG lasers ua haujlwm ntawm lawv lub tswv yim wavelamental (1064 nm) lossis Harmonics (piv txwv li 532 nm) tau muaj lub tswv yim zoo tshaj plaws rau libs.

1.2 Taw qhia rau lub erbium -} doped iav laser
Lub Ecbium -}}}}}}}}}}}} lub xeev laser nyob qhov twg cov nquag nruab nrab yog cov iav matrix doped nrog er³ned. Nws cov zis tseem ceeb tshaj plaws yog ntawm nthwv dej ntawm 2.94 μm, sib txuas nrog kev hloov pauv ntawm ⁴i₁₁ / ₂ thiab ⁴i₁₃ / ₂ zog qib ntawm er³. Cov nthwv dej tshwj xeeb no tso nws nyob rau hauv nruab nrab- Infrared (m} ir) cheeb tsam hluav taws xob.

1.3 lub hom phiaj thiab tseem ceeb
Txawm tias muaj kev vam meej ntawm ND: yag - lib, tshwj xeeb hais txog kev tsom xam thiab teeb liab}- suab nrov rau cov ntsiab lus tsis zoo. Tus ER: iav laser, nrog nws cov wavelengtength, nthuav tawm cov kev sib tw no los ntawm kev siv tshuab sib txawv, yog li nthuav dav cov khaub ncaws ntawm libs.

2. Lub hom phiaj ntawm ER: iav laser - kev sib txuam

Qhov tshwj xeeb hluav taws xob ntawm ER: iav laser hauv libs los ntawm ib qho kev tshwm sim ntawm lub cev tseem ceeb: lub zog nqus ntawm 2.94 μm hluav taws xob los ntawm dej.

2.1 Cov dej muaj zog dej nqus lub ncov
Dej lwg xws li muaj zog heev rau qhov muaj zog heev rau kev nqus cov kab ua ke muaj ntsej muag sib txawv ntawm 2.94 μm. Qhov kev nqus no yog kev txiav txim siab ntawm qhov ntau dua ntawm tus qauv ND: YAG Wavelength ntawm 1064 nm.

2.2 Lub Zog Hluav Taws Xob Txhim Kho Zog
Thaum twg 2.94 μm laser mem tes iradiates ib qho piv txwv uas muaj dej (piv txwv li, cov roj ntsha, cov roj ntsha liner), cov roj ntsha liner yog tso tawm kom muaj txiaj ntsig thiab zoo tshaj plaws hauv tus qauv. Qhov nrawm dua thiab ib cheeb tsam lub zog nqus ua rau nrawm thiab tawg vaporization ntawm cov ntsiab lus dej. Cov txheej txheem no, piv rau nws siv hauv laser phais, tau tshwm sim hauv:

Txhim Kho Ablation:Lub micro - tawg eject ntau cov khoom siv rau hauv cov ntshav.
