Edinburgh Picosecond Pulse Laser kukonza

Mndandanda wa Edinburgh Laser HPL ndi laser ya picosecond pulse differential yopangidwira muyeso wa TCSPC. Mfundo yogwirira ntchito imachokera ku mawonekedwe a kusiyana kwa semiconductor. M'zinthu za semiconductor, polowetsa kutsogolo kwamakono, ma elekitironi ndi mabowo omwe ali m'dera logwira ntchito (nthawi zambiri amapangidwa ndi zipangizo zamtundu wa semiconductor monga kusiyana kothekera) amapangidwa polarized. Photon ikayambitsa chigawochi, imayambitsa njira yolimbikitsira yotulutsa, kupanga mafotoni ndi nthawi yomweyo, kulunzanitsa, kutumizirana mauthenga ndi njira yofalitsa monga photon, potero kukwaniritsa kukulitsa kuwala.

2. Zambiri zolakwika

(I) Palibe kutulutsa kwa laser

Vuto lamagetsi: Laser ya HPL imafuna 15 VDC yokhazikika +/- 5%, 15W DC magetsi (kupyolera mu 2.1) Ngati magetsi sali okhazikika, monga magetsi ndi otsika kwambiri kapena okwera kwambiri (kunja kwa malo ovomerezeka), laser ikhoza kugwira ntchito bwino. Mwachitsanzo, magetsi akawonongeka kapena dera lamkati likulephera, zomwe zimapangitsa kuti voteji ikhale yotsika kuposa 14.25V, laser ikhoza kuyamba, zomwe sizingatulutse laser. Kuphatikiza apo, pulagi yamagetsi yotayirira kapena kusalumikizana bwino kungayambitsenso kusokonezeka kwamagetsi, zomwe zimapangitsa kuti laser isatuluke.

(II) Mphamvu ya laser yachilendo

Kuyika kwa laser kolakwika pakugwira ntchito: Laser ya HPL ili ndi njira ziwiri zogwirira ntchito: mawonekedwe okhazikika komanso mphamvu yayikulu. Ngati njira yogwirira ntchito imayikidwa molakwika panthawi yoyesera, mwachitsanzo, mawonekedwe amphamvu kwambiri amayenera kusankhidwa kuti adziwe mphamvu zowonjezera zowonjezera, koma zimayikidwa kuti zikhale zoyenera, mphamvu yotulutsa laser idzakhala yochepa kuposa momwe ikuyembekezeredwa. Kuonjezera apo, pokonza njira yogwirira ntchito, ngati ntchitoyo ili yosayenera, monga zolakwika za kufalitsa malangizo panthawi yosinthira, laser ikhoza kuwoneka mumsewu wosagwira ntchito, zomwe zimapangitsa kuti pakhale mphamvu zowonongeka.

Kuipitsidwa kwa zigawo zowoneka bwino: Ngati pamwamba pazigawo zomwe zili mkati mwa laser (monga fyuluta yomangidwira kuti muchepetse kutulutsa kunja kwa gulu) yaipitsidwa ndi fumbi, mafuta ndi zotumphukira zina, zimakhudza kufalikira ndi kufalikira kwa laser. Tinthu tating'onoting'ono ta laser titha kuyatsa laser, ndikupangitsa mphamvu ya laser kutayika panthawi yofalitsa, zomwe zimapangitsa kuchepa kwa mphamvu.

III. Njira zosamalira

(I) Kuyeretsa nthawi zonse

Kuyeretsa chigawo cha Optical: Kuyeretsa magawo mkati mwa laser nthawi zonse ndikofunikira. Pazosefera zomangidwira, mutha kugwiritsa ntchito chopukuta choyera, chofewa, chopanda lint kuti mupukute pang'onopang'ono kuti muchotse pamwamba pa pukuta ndi kupukuta. Mukamapukuta, samalani kuti musakanda pamwamba pa fyulutayo ndi mphamvu. Pazigawo zina zowoneka bwino monga ma collimators omwe ali ndi mafuta kapena madontho ena omwe ndi ovuta kuyeretsa, mutha kugwiritsa ntchito chotsukira chapadera (monga isopropyl mowa, etc.), dontho chotsukira pa chiguduli, kenako ndikupukuta pang'onopang'ono pamwamba pa gawo la kuwala, koma samalani kuti musagwiritse ntchito zotsukira kwambiri, apo ayi zitha kuwononga zida zina.

Kuyeretsa kunja: Gwiritsani ntchito nsalu yonyowa poyera kuti mupukute kunja kwa laser kuchotsa fumbi ndi madontho pamwamba. Chovala chonyowacho chiyenera kuphwanyidwa kuti chiteteze chinyezi kuti chisalowe mu mawonekedwe a magetsi kapena zigawo zina zomveka mkati mwa laser.

(II) Yang'anani zigawo zogwirizanitsa

Chekeni cholumikizira mphamvu: Yang'anani nthawi zonse ngati pulagi yamagetsi imalumikizidwa ndi socket mwachangu komanso ngati chingwe cha adapter yamagetsi chawonongeka kapena kusweka. Ngati pulagi ikupezeka kuti ndi yotayirira, iyenera kubwezeretsedwanso pakapita nthawi; ngati chingwe chawonongeka, adaputala yamagetsi iyenera kusinthidwa nthawi yomweyo kuti iwonetsetse kuti magetsi azikhala okhazikika.

(III) Kuwongolera chilengedwe

Kuwongolera kutentha: Perekani malo oyenera kutentha kwa laser HPL. Nthawi zambiri tikulimbikitsidwa kuwongolera kutentha kwa ntchito pakati pa 15 ℃ - 35 ℃. Kuyika makina owongolera mpweya mu labotale kumatha kukhazikika kutentha kwamkati mkati mwamtunduwu. Kwa ma lasers omwe amagwira ntchito mosalekeza kwa nthawi yayitali, mutha kuganizira zowakonzekeretsa ndi zida zapadera zozizirira, monga kuziziritsa mpweya kapena kuziziritsa madzi, kuwonetsetsa kuti magwiridwe antchito a laser sangachepe chifukwa cha kutentha kwambiri panthawi yogwira ntchito.

(IV) Kuyesedwa kwanthawi zonse

Kuyesa kwamphamvu kwa laser: Gwiritsani ntchito mita yamagetsi kuti muyese nthawi zonse mphamvu yotulutsa laser ndikuyerekeza mphamvu yeniyeni yotulutsa ndi mtengo wamagetsi womwe wafotokozedwa mu bukhu laukadaulo la laser. Yesani pansi pa chilengedwe chokhazikika.
