Kev Txhim Kho Keeb Kwm Ntawm Picosecond Laser

Kev Txhim Kho Keeb Kwm ntawm Picosecond Laser

Picosecond laser tau dhau los ua cov thev naus laus zis thev naus laus zis hauv kev kho mob cosmetology hauv xyoo tas los no. Nws cov kev ua tau zoo heev, kev ua haujlwm siab, thiab cov yam ntxwv tsis cuam tshuam tau dav lees paub thiab nyiam los ntawm cov neeg thoob plaws ntiaj teb. Txoj kev loj hlob ntawm picosecond laser tshuab tuaj yeem taug qab rov qab mus rau thaum ntxov 1970s thaum nws yog thawj zaug los ntawm cov kws tshawb fawb.

Xyoo 1970, thawj picosecond laser tau tsim los ntawm ib pab pawg neeg tshawb fawb ntawm Bell Laboratories hauv Tebchaws Meskas. Lawv siv hom-locked dye laser kom ua tiav thawj picosecond mem tes, uas tsuas yog ob peb picoseconds ntev. Txawm li cas los xij, vim muaj kev txwv ntawm thev naus laus zis nyob rau lub sijhawm ntawd, nws nyuaj rau tswj picosecond pulses. Yog li ntawd, picosecond mem tes laser tsis tau dav siv kom txog thaum xyoo 1980s.

Nyob rau xyoo 1980, nrog rau kev txhim kho sai ntawm laser technology, cov kws tshawb fawb tau qhia txog kev siv picosecond pulses hauv lwm qhov chaw. Piv txwv li, picosecond pulses tau siv nyob rau hauv fluorescence lifetime imaging microscopy thiab time-resolved spectroscopy. Lub caij no, cov kws tshawb nrhiav txuas ntxiv tsim cov txheej txheem pulse compression kom ua tiav cov txiaj ntsig picosecond pulse ruaj khov.

Hauv xyoo 2000s, picosecond lasers tau siv thawj zaug hauv kev kho mob ntawm ophthalmology. Ib pawg kws tshawb fawb los ntawm Tebchaws Meskas thiab Lub Tebchaws Yelemees tau qhia txog kev siv femtosecond lasers hauv kev phais refractive. Femtosecond lasers muab qhov tseeb thiab ruaj khov pulse tso zis ntau dua li yav dhau los lasers, ua rau muaj kev txhim kho tseem ceeb hauv kev phais raug thiab ua tau zoo.

Hauv xyoo 2012, ib pab pawg neeg tshawb fawb los ntawm Tebchaws Meskas thawj zaug tau thov siv picosecond lasers rau kev tshem tawm tattoo. Lub picosecond laser siv nyob rau hauv kev tshem tawm tattoo tau luv luv mem tes ntev dua li yav dhau los lasers, uas tuaj yeem rhuav tshem tattoo pigments sai dua thiab zoo dua yam tsis ua rau daim tawv nqaij puas. Kev taw qhia ntawm picosecond lasers hauv kev tshem tawm tattoo cim lub sijhawm tshiab hauv kev kho mob cosmetology.

Txij thaum ntawd los, cov kws tshawb fawb thoob ntiaj teb tau tshawb nrhiav kev siv picosecond lasers hauv kev kho mob thiab tshuaj pleev ib ce. Picosecond lasers tau siv nyob rau hauv ntau yam kev kho kom zoo nkauj, nrog rau cov tawv nqaij rejuvenation, pigmentation tshem tawm, thiab kho caws pliav. Nrog nws cov yam ntxwv tsis muaj kev cuam tshuam, nrawm, nyab xeeb, thiab cov yam ntxwv zoo, picosecond laser thev naus laus zis tau dhau los lees paub tias yog qhov tseem ceeb hauv kev kho mob cosmetology.

Ntxiv mus, kev ua lag luam rau picosecond lasers tau loj hlob sai. Ntau lub tuam txhab tau tsim picosecond laser tshuab, thiab ntau lub tsev kho mob thiab chaw kho mob tau pib muab picosecond laser kho. Kev maj mam nrov ntawm picosecond laser thev naus laus zis tau coj cov kev hloov pauv loj heev rau kev lag luam kho mob cosmetology.

Hauv kev xaus, txoj kev loj hlob ntawm picosecond laser tshuab tau dhau los ntawm cov txheej txheem ntev ntawm kev tsim kho tshiab thiab kev txhim kho. Los ntawm thawj picosecond mem tes laser rau niaj hnub no picosecond laser tshuab, cov cuab yeej tau ua tiav kev txhim kho tseem ceeb hauv kev ruaj ntseg, raug, thiab ua haujlwm tau zoo. Daim ntawv thov kev vam meej ntawm picosecond lasers hauv kev kho mob cosmetology tau coj kev cia siab tshiab thiab lub sijhawm rau cov neeg mob nrhiav kev kho kom zoo nkauj nyab xeeb thiab zoo.
