Koj puas tuaj yeem qhia qhov txawv ntawm nanosecond laser, picosecond laser thiab femtosecond laser?

Ua ntej, cia peb xav seb cov "thib ob" txhais li cas.

1 nanocond = 10 ^-9 thib ob

1 picocond = np 10 ^-12 thib ob

1 femtosecond = 10 ^-15 thib ob

Yog li ntawd, qhov sib txawv loj ntawm nanosecond laser, picosecond laser thiab femtosecond laser lies nyob rau hauv lawv lub sij hawm ntev.

Lub ntsiab lus ntawm utlrafast laser

Ntev dhau los, tib neeg sim siv laser los ua micromachining. Txawm li cas los xij, txij li cov laser ib txwm muaj qhov ntev mem tes dav thiab tsis tshua muaj laser siv, cov ntaub ntawv yuav tsum tau ua kom yooj yim rau yaj thiab ua kom evaporating. Txawm hais tias laser beam tuaj yeem tsom mus rau hauv qhov chaw me me heev, qhov kub ntawm qhov cuam tshuam rau cov ntaub ntawv tseem loj heev, uas txwv qhov precision ntawm kev ua. Tsuas yog txo cov nyhuv tshav kub tuaj yeem txhim kho qhov ua tau zoo.

Tab sis thaum ultrafast laser ua haujlwm ntawm cov ntaub ntawv, cov nyhuv ua tau muaj kev hloov pauv loj. Raws li lub zog mem tes nce ntau, lub zog siab ceev yog muaj zog txaus los ua kom cov khoom siv hluav taws xob sab nraud. Txij li thaum kev sib cuam tshuam ntawm ultrafast laser thiab cov ntaub ntawv yog luv luv, cov ion twb tau ablated rau ntawm cov khoom nto ua ntej nws conveys lub zog rau cov ntaub ntawv nyob ib puag ncig, yog li ntawd tsis muaj cua sov yuav raug coj mus rau cov ntaub ntawv nyob ib puag ncig. Yog li ntawd, ultrafast laser ua kuj hu ua txias ua.

Muaj ntau yam kev siv ntawm ultrafast laser hauv kev tsim khoom. Hauv qab no peb yuav muab ob peb lub npe:

1.Qhov drilling

Nyob rau hauv lub Circuit Court board tsim, tib neeg pib siv ceramics foundation los hloov cov tsoos yas lub hauv paus kom paub zoo dua tshav kub conductivity. Txhawm rau txuas cov khoom siv hluav taws xob, ntau txhiab tus μm theem me qhov yuav tsum tau drilled ntawm lub rooj tsavxwm. Yog li ntawd, ua kom lub hauv paus ruaj khov yam tsis muaj kev cuam tshuam los ntawm cov cua sov nkag thaum lub qhov drilling tau ua qhov tseem ceeb heev. Thiab picosecond lase yog cov cuab yeej zoo tshaj plaws.

Picosecond laser paub lub qhov drilling los ntawm percussion tho txawv thiab ua kom lub cev sib xws ntawm lub qhov. Ntxiv nrog rau lub rooj tsav xwm hauv Circuit Court, picosecond laser kuj tseem siv tau los ua qhov zoo drilling ntawm cov yas nyias zaj duab xis, semiconductor, hlau zaj duab xis thiab sapphire.

2.Scribing thiab txiav

Ib txoj kab tuaj yeem tsim los ntawm kev soj ntsuam tas li kom overlay lub laser mem tes. Qhov no yuav tsum muaj ntau qhov kev txheeb xyuas kom nkag mus tob rau hauv cov ceramics kom txog thaum cov kab tau mus txog 1/6 ntawm cov khoom tuab. Tom qab ntawd cais txhua tus neeg module los ntawm lub hauv paus ceramics nrog rau cov kab no. Qhov kev sib cais no hu ua scribing.

Lwm txoj kev sib cais yog pulse laser ablation txiav. Nws yuav tsum tau ablating cov khoom kom txog thaum cov khoom raug txiav tag.

Rau saum toj saud thiab txiav, picosecond laser thiab nanosecond laser yog cov kev xaiv zoo tshaj plaws.

3. Txheej tshem tawm

Lwm daim ntawv thov micromachining ntawm ultrafast laser yog txheej tshem tawm. Qhov no txhais tau hais tias tshem tawm cov txheej txheem yam tsis muaj kev puas tsuaj los yog me ntsis ua rau cov ntaub ntawv hauv paus. Lub ablation tuaj yeem yog kab ntawm ob peb micrometer dav lossis loj nplai ntawm ob peb square centimeters. Txij li qhov dav ntawm cov txheej yog ntau me dua qhov dav ntawm ablation, lub tshav kub yuav tsis hloov mus rau sab. Qhov no ua rau nanosecond laser tsim nyog heev.

Ultrafast laser muaj peev xwm zoo thiab muaj kev vam meej yav tom ntej. Nws nta tsis tas yuav tsum tau ua tom qab ua tiav, yooj yim ntawm kev sib koom ua ke, kev ua haujlwm siab, siv cov khoom siv tsawg, tsis muaj kuab paug ib puag ncig. Nws tau dav siv hauv tsheb, hluav taws xob, khoom siv, machinery manufacturing, thiab lwm yam. Txhawm rau kom ultrafast laser khiav ceev hauv lub sijhawm ntev, nws qhov kub thiab txias yuav tsum tau tswj kom zoo. S&Ib Teyu CWUP series portable dej chillers yog zoo tagnrho rau txias ultrafast lasers mus txog 30W. Cov laser chiller units muaj cov qib siab ntawm precision ntawm ±0.1 ℃ thiab txhawb Modbus 485 kev sib txuas lus muaj nuj nqi. Nrog rau kev tsim cov raj xa dej kom zoo, lub caij nyoog ntawm kev tsim cov npuas tau dhau los ua slim, uas txo qhov cuam tshuam rau ultrafast laser.
