Nanoseconds, picoseconds, thiab femtoseconds yog lub sij hawm units, 1 thib ob= 103 milliseconds=106 microseconds=109 nanoseconds=1012 picoseconds=1015 femtoseconds, picosecond laser thiab nanosecond laser xa mus rau Lub sijhawm ua haujlwm ntawm ib leeg laser mem tes (Pulse width) hauv picosecond, qib nanosecond. Txoj kev ua laser yog siv lub zog loj laser beam kom irradiate saum npoo ntawm cov khoom tom qab tsom mus ua rau lub cev lossis tshuaj tiv thaiv. Nws yog ib qho tseem ceeb ntawm kev ua thermal, tab sis vim lub sij hawm luv luv, feem ntau nyob rau hauv ob peb nanoseconds. Yog li ntawd, lub tshav kub-cuam tshuam cheeb tsam yog me me, thiab cov nyhuv ua thiab kev ceev yuav guaranteed. Picosecond lasers thiab femtosecond lasers nrog luv luv pulse widths tau ua tiav cov txheej txheem hauv kev lag luam laser thiab hu ua micro-precision ultra-ceev laser ua tshuab.
Lub picosecond laser muaj lub sijhawm luv luv luv, thiab lub sijhawm ua haujlwm ntawm ib lub mem tes tsuas yog ob peb picoseconds, yog li nws cov nyhuv thermal me me, lossis txawm tias tsis pom zoo. Sib txawv ntawm kev ua ntawm nanosecond laser txiav tshuab, picosecond laser tsis recast cov khoom thaum lub sij hawm tag nrho cov txheej txheem, cov txheej txheem yog huv si, thiab nqus ntawm laser zog yog tsawg nyob ntawm cov khoom los yog wavelength. Nyob rau tib lub sijhawm, lub sijhawm ua haujlwm luv luv, qhov tseeb yog siab dua, thiab kev ua haujlwm nrawm dua.
Piv nrog rau nanosecond laser, picosecond laser txiav tshuab muaj kev ua haujlwm zoo dua thiab ua haujlwm ceev. Nyob rau hauv daim ntawv thov kev lag luam, lub picosecond laser kuj muaj qhov chaw dav dua, xws li lub hnub ci cell laser etching (txoj kab dav), OLED laser txiav (me me chipping), laser drilling ntawm nkig cov ntaub ntawv (ceev ceev), thiab lwm yam.
Ntawm chav kawm, tam sim no mainstream laser ua lag luam yog tseem dominated los ntawm nanosecond lasers. Yog vim li cas yog tus nqi siab ntawm picosecond ultrafast laser txiav tshuab. Cov qauv yav tom ntej yuav tsum yog picoseconds thiab femtoseconds.
