Taw qhia
Lasers, lub ntsiab lus rau lub teeb Amplification los ntawm Stimulated Emission of Radiation, yog cov cuab yeej siv dav hauv ntau qhov chaw. Lawv paub txog lawv qhov kev siv siab, monochromatic, thiab cov khoom taw qhia. Lasers tuaj yeem muab faib ua ob hom tseem ceeb: lasers txuas ntxiv thiab cov lasers pulsed. Kab lus no yuav tham txog qhov sib txawv ntawm lawv daim ntawv thov.
Nruam Lasers
Txhais thiab Cov Khoom
Nruam lasers, tseem hu ua CW (Nruam Wave) lasers, emit laser teeb tsis tu ncua nrog ib qho kev siv tas li. Lawv muaj lub zog siab kawg nkaus tab sis siab nruab nrab lub zog. Cov kab hluav taws xob tso tawm tau ruaj khov, thiab lub zog tseem nyob ib puag ncig lub sijhawm ntev.
Daim ntawv thov
Nruam lasers feem ntau yog siv nyob rau hauv daim ntaub ntawv uas yuav tsum tau ib tug zoo ib yam thiab ruaj khov tso zis. Qee qhov piv txwv suav nrog:
Kev ua cov khoom siv: Engraving, txiav, thiab vuam ntau yam ntaub ntawv xws li hlau, yas, thiab iav.
Kev sib txuas lus: Hauv fiber ntau optic tes hauj lwm, CW lasers yog siv rau kev sib kis mus ntev thiab khaws cov ntaub ntawv.
Kev ntsuas thiab kev sib dhos: Hauv cov cuab yeej ua haujlwm siab, xws li interferometers thiab rangefinders.
Tshuaj: Rau cov txheej txheem phais, dermatology, thiab ophthalmology.
Pulsed Lasers
Txhais thiab Cov Khoom
Pulsed lasers emit laser lub teeb nyob rau hauv luv luv, khaus tawg los yog pulses. Lawv muaj lub zog ncov ntau dua piv rau cov lasers tas li. Lub sijhawm ntawm txhua tus mem tes yuav txawv ntawm nanoseconds mus rau microseconds. Pulsed lasers tuaj yeem ua tiav lub zog siab dua ib lub mem tes los ntawm kev sib sau lub zog hauv cov khoom cia, xws li lub capacitor lossis laser siv lead ua.
Daim ntawv thov
Pulsed lasers nyiam nyob rau hauv cov ntawv thov uas xav tau lub zog siab thiab lub sijhawm luv mem tes. Qee qhov piv txwv suav nrog:
Cov khoom siv: Kev kub ceev txiav thiab drilling ntawm cov hlau tuab, nrog rau ablation thiab kev kho deg.
Kev tiv thaiv thiab kev ruaj ntseg: Hauv laser rangefinders, lub hom phiaj tsim, thiab laser dazzlers.
Kev tshawb fawb txog kev tshawb fawb: Rau kev kawm cov txheej txheem ultrafast thiab lub zog siab physics.
Tshuaj: Rau kev tshem tawm tattoo, tawv nqaij resurfacing, thiab cov txheej txheem kho hniav.
Xaus
Nruam thiab pulsed lasers muaj cov khoom sib txawv thiab kev siv nyob ntawm qhov yuav tsum tau muaj ntawm cov ntaub ntawv siv tshwj xeeb. Nruam lasers yog haum rau daim ntaub ntawv uas yuav tsum tau ib tug zoo ib yam thiab ruaj khov tso zis, thaum pulsed lasers nyiam thaum lub zog siab thiab luv mem tes ntev yog tsim nyog. Nkag siab qhov sib txawv ntawm ob hom lasers no tuaj yeem pab xaiv cov cuab yeej tsim nyog tshaj plaws rau ib daim ntawv thov tshwj xeeb.
