Njira yowunikira yolumikizira laser

Kuwotcherera kwa lasernjira yoganizira kwambiri

Pamene laser ikakumana ndi chipangizo chatsopano kapena ikuchita kafukufuku watsopano, gawo loyamba liyenera kukhala kuyang'ana. Pokhapokha pofufuza malo ofunikira, magawo ena a njira monga kuchepetsa kuchuluka kwa zinthu, mphamvu, liwiro, ndi zina zotero angadziwike bwino, kuti amvetsetse bwino.

Mfundo yoganizira kwambiri ndi iyi:

Choyamba, mphamvu ya kuwala kwa laser siigawidwa mofanana. Chifukwa cha mawonekedwe a hourglass kumbali yakumanzere ndi yakumanja ya galasi loyang'ana, mphamvuyo imakhala yolimba kwambiri komanso yamphamvu kwambiri pamalo a m'chiuno. Kuti muwonetsetse kuti ntchito ikuyenda bwino komanso yabwino, nthawi zambiri ndikofunikira kupeza malo olunjika ndikusintha mtunda wochotsa kukhazikika kutengera izi kuti mugwiritse ntchito chinthucho. Ngati palibe malo olunjika, magawo otsatirawa sadzakambidwa, ndipo kukonza zolakwika pazida zatsopano kuyeneranso kudziwa kaye ngati malo olunjika ndi olondola. Chifukwa chake, kupeza malo olunjika ndi phunziro loyamba muukadaulo wa laser.

Monga momwe zasonyezedwera mu Zithunzi 1 ndi 2, mawonekedwe a kuya kwa ma laser okhala ndi mphamvu zosiyanasiyana ndi osiyana, ndipo ma galvanometer ndi ma single mode ndi ma multimode laser nawonso ndi osiyana, makamaka omwe amawonetsedwa mu kugawa kwa malo. Ena ndi ochepa, pomwe ena ndi ofooka. Chifukwa chake, pali njira zosiyanasiyana zowunikira ma laser osiyanasiyana, zomwe nthawi zambiri zimagawidwa m'magawo atatu.

Chithunzi 1 Chithunzi chojambula cha kuya kwa malo osiyanasiyana a kuwala

Chithunzi 2 Chithunzi cha schematic cha kuya kwa focal pa mphamvu zosiyanasiyana

Kukula kwa malo otsogolera pa mtunda wosiyana

Njira yopendekera:

1. Choyamba, dziwani kutalika kwa malo owunikira potsogolera malo owala, ndipo dziwani malo owala kwambiri komanso ang'onoang'ono kwambiri a malo owala owongolera ngati malo oyamba oyesera;

2. Kapangidwe ka pulatifomu, monga momwe zasonyezedwera pa Chithunzi 4

Chithunzi 4 Chithunzi cha zida zoyang'ana mzere wopingasa

2. Malangizo opewera kugwedezeka mopingasa

(1) Kawirikawiri, mbale zachitsulo zimagwiritsidwa ntchito, ndi ma semiconductor mkati mwa 500W ndi ulusi wa kuwala pafupifupi 300W; Liwiro likhoza kukhazikitsidwa pa 80-200mm

(2) Ngodya yopendekera ya mbale yachitsulo ikakula, zimakhala bwino, yesetsani kukhala pafupifupi madigiri 45-60, ndikuyika pakati pa malo ozungulira okhala ndi malo owunikira ang'onoang'ono komanso owala kwambiri;

(3) Kenako yambani kulumikiza zingwe, kodi kulumikiza zingwe kumakhudza bwanji? M'malingaliro, mzerewu udzagawidwa mozungulira malo ofunikira, ndipo njira yolowera idzadutsa mu njira yokulira kuchokera pa yayikulu kupita pa yaying'ono, kapena kuwonjezeka kuchokera pa yaying'ono kupita pa yayikulu kenako ndikuchepa;

(4) Ma semiconductor amapeza mfundo yopyapyala kwambiri, ndipo mbale yachitsulo idzakhalanso yoyera pamalo ofunikira okhala ndi mawonekedwe omveka bwino amitundu, zomwe zingagwiritsidwenso ntchito ngati maziko opezera malo ofunikira;

(5) Kachiwiri, fiber optic iyenera kuyesetsa kulamulira kulowa kwa micro kumbuyo momwe ingathere, ndi kulowa kwa micro pamalo ofunikira, kusonyeza kuti malo ofunikira ali pakati pa kutalika kwa kulowa kwa micro kumbuyo. Pamalo amenewa, malo ofunikira a focal point amatsirizika, ndipo malo othandizidwa ndi laser amagwiritsidwa ntchito pa sitepe yotsatira.

Chithunzi 5 Chitsanzo cha mizere yopingasa

Chithunzi 5 Chitsanzo cha mizere yopingasa pa mtunda wosiyanasiyana wogwirira ntchito

3. Gawo lotsatira ndikulinganiza ntchito, kusintha laser ya mzere kuti igwirizane ndi kuyang'ana chifukwa cha malo owunikira, omwe ndi kuyang'ana komwe kuli, kenako kuchita kutsimikizira komaliza kwa focal plane

(1) Kutsimikizira kumachitika pogwiritsa ntchito mfundo za pulse. Mfundo yake ndi yakuti ma sparks amathiridwa pamalo ofunikira, ndipo makhalidwe a mawu ndi omveka bwino. Pali malire pakati pa malire apamwamba ndi otsika a malo ofunikira, komwe mawuwo ndi osiyana kwambiri ndi ma sparks ndi ma sparks. Lembani malire apamwamba ndi otsika a malo ofunikira, ndipo pakati ndiye malo ofunikira,

(2) Sinthani mzere wa laser womwe umagwirizananso, ndipo cholinga chake chili kale ndi cholakwika cha pafupifupi 1mm. Mutha kubwereza malo oyesera kuti muwongolere kulondola.

Chithunzi 6 Chiwonetsero cha Spark Splash pa Maulendo Osiyanasiyana Ogwira Ntchito (Kuchuluka Kochotsa Kuyang'ana)

Chithunzi 7 Chithunzi cha kugunda kwa mtima ndi kuyang'ana kwambiri

Palinso njira yopezera madontho: yoyenera ma laser a ulusi okhala ndi kuya kwakukulu kwa focal ndi kusintha kwakukulu kwa kukula kwa malo mu Z-axis. Pogogoda mzere wa madontho kuti muwone kusintha kwa mfundo pamwamba pa mbale yachitsulo, nthawi iliyonse Z-axis ikasintha ndi 1mm, chizindikiro pa mbale yachitsulo chimasintha kuchokera pa chachikulu kupita pa chaching'ono, kenako kuchokera pa chaching'ono kupita pa chachikulu. Mfundo yaying'ono kwambiri ndi focal point.
