Lus
Laser thev naus laus zis tau nce siab sai hauv ob peb lub xyoo dhau los. Los ntawm nanosecond laser mus rau picosecond laser rau femtosecond laser, nws tau maj mam thov nyob rau hauv industrial manufacturing, muab kev daws teeb meem rau txhua qhov chaw ntawm lub neej. Tab sis koj paub ntau npaum li cas txog 3 hom lasers? Kab lus no yuav tham txog lawv cov ntsiab lus, lub sijhawm hloov pauv chav, kev siv kho mob thiab dej chiller txias tshuab.

Cia peb kawm ua ke:
Cov ntsiab lus ntawm Nanosecond, Picosecond, thiab Femtosecond Lasers
Nanosecond laser yog thawj zaug nkag mus rau hauv kev lag luam teb thaum xyoo 1990s raws li diode-pumped solid-state (DPSS) lasers. Txawm li cas los xij, thawj cov lasers muaj lub zog qis qis ntawm ob peb watts thiab wavelength ntawm 355nm. Sij hawm dhau mus, kev ua lag luam rau nanosecond lasers tau matured, thiab feem ntau lasers tam sim no muaj mem tes ntev nyob rau hauv kaum rau pua pua ntawm nanoseconds.
Picosecond laser yog ib qho ultra-luv mem tes dav laser uas emits picosecond-theem pulses. Cov lasers no muaj qhov dav dav dav dav dav dav dav, kho tau ntau zaus, lub zog pulse siab, thiab zoo tagnrho rau kev siv hauv biomedicine, optical parametric oscillation, thiab bio microscopic imaging. Nyob rau hauv niaj hnub biological imaging thiab tsom xam systems, picosecond lasers tau dhau los ua cov cuab yeej tseem ceeb.
Femtosecond laser yog ib qho ultra-luv mem tes laser nrog ib qho kev siv siab kawg, xam hauv femtoseconds. Qhov kev siv thev naus laus zis no tau muab rau tib neeg nrog qhov kev sim tshiab tsis tau pom dua thiab muaj kev siv dav dav. Kev siv lub zog ultra-muaj zog, luv-pulsed femtosecond laser rau kev tshawb nrhiav lub hom phiaj yog tshwj xeeb tshaj yog zoo rau ntau yam tshuaj tiv thaiv, nrog rau tiam sis tsis txwv rau daim ntawv cog lus cleavage, tshiab daim ntawv cog lus tsim, proton thiab electron hloov, compound isomerization, molecular dissociation, ceev, lub kaum sab xis. , thiab lub xeev faib ntawm cov tshuaj tiv thaiv intermediates thiab cov khoom kawg, tshuaj lom neeg cov tshuaj tiv thaiv tshwm sim hauv cov kev daws teeb meem thiab kev cuam tshuam ntawm cov kuab tshuaj, nrog rau kev cuam tshuam ntawm molecular vibration thiab kev sib hloov ntawm cov tshuaj tiv thaiv.
Lub Sijhawm Hloov Hloov Chav rau Nanoseconds, Picoseconds, thiab Femtoseconds
1ns (nanosecond) = 0.0000000000 vib nas this = 10-9 vib nas this
1ps (picosecond) = 0.0000000000000 vib nas this = 10-12 vib nas this
1fs ib (femtosecond) = 0.000000000000001 vib nas this = 10-15 vib nas this
Lub nanosecond, picosecond, thiab femtosecond laser ua khoom siv feem ntau pom hauv khw muaj npe raws sijhawm. Lwm yam, xws li ib leeg mem tes zog, mem tes dav, mem tes zaus, thiab mem tes ncov lub zog, kuj ua lub luag haujlwm hauv kev xaiv cov khoom tsim nyog rau kev ua cov khoom sib txawv. Lub sijhawm luv dua, qhov cuam tshuam tsawg dua ntawm cov khoom siv nto, ua rau muaj kev ua haujlwm zoo dua.
Kev siv kho mob ntawm Picosecond, Femtosecond, thiab Nanosecond Lasers
Nanosecond lasers xaiv cov cua sov thiab rhuav tshem melanin hauv daim tawv nqaij, uas tom qab ntawd tshem tawm ntawm lub cev los ntawm cov hlwb, uas ua rau fading ntawm pigmented lesions. Txoj kev no feem ntau yog siv rau kev kho mob ntawm pigmentation teeb meem. Picosecond lasers ua haujlwm ntawm kev kub ceev, rhuav tshem melanin hais yam tsis muaj kev puas tsuaj rau daim tawv nqaij. Txoj kev no zoo kho cov kab mob pigmented xws li nevus ntawm Ota thiab Brown cyan nevus.Femtosecond laser ua haujlwm nyob rau hauv daim ntawv ntawm pulses, uas muaj peev xwm emit lub hwj chim loj nyob rau hauv ib qho instant, zoo rau kev kho mob ntawm myopia.
Txias System rau Picosecond, Femtosecond, thiab Nanosecond Lasers
Tsis muaj teeb meem ntawm nanosecond, picosecond lossis femtosecond laser, nws yog ib qho tsim nyog los xyuas kom meej lub cev ua haujlwm ntawm lub taub hau laser thiab ua ke cov khoom siv nrog lub tshuab ua haujlwm. laser tshuab chiller. Qhov tseeb dua cov khoom siv laser, qhov siab dua qhov kev tswj qhov kub thiab txias. TEYU ultrafast laser chiller muaj qhov kub thiab txias ntawm ± 0.1 ° C thiab cua txias sai, uas ua kom lub laser ua haujlwm ntawm qhov kub thiab txias thiab muaj cov kab hluav taws xob ruaj khov, yog li txhim kho lub neej kev pab cuam ntawm lub laser. TEYU ultrafast laser chillers tsim nyog rau tag nrho peb hom khoom siv laser.
