GW Nanosecond pulsed solid-state laser kukonza

GW YLPN-1.8-2 500-200-F ndi laser yolondola kwambiri ya nanosecond short-pulse laser (DPSS, diode-pumped solid-state laser) yopangidwa ndi GWU-Lasertechnik (yomwe tsopano ili gawo la Laser Components Group) ku Germany. Amagwiritsidwa ntchito kwambiri mu:

Industrial micromachining (kubowola kwa PCB, kudula magalasi)

Kufufuza kwasayansi (kuwunika kwa spectral, laser-induced breakdown spectroscopy LIBS)

Kukongola kwachipatala (kuchotsa mtundu wa pigmentation, opaleshoni yochepa kwambiri).

Core parameters:

Wavelength: 532nm (kuwala kobiriwira) kapena 355nm (ultraviolet)

Kuthamanga kwamphamvu: 1.8 ~ 2ns

Kubwereza pafupipafupi: 500Hz ~ 200kHz zosinthika

Mphamvu yapamwamba: kachulukidwe kamphamvu kwambiri, koyenera kukonza bwino.

2. Njira zosamalira tsiku ndi tsiku

(1) Kusamalira dongosolo la Optical

Kuyang'anira sabata iliyonse:

Gwiritsani fumbi wopanda fumbi wothinikizidwa kuyeretsa laser linanena bungwe zenera ndi reflector.

Yang'anani mayalidwe a njira ya kuwala (kupewa kupatuka chifukwa cha kugwedezeka kwamakina).

Kukonza mozama kotala:

Gwiritsani ntchito chotsukira chapadera + chotsuka thonje chopanda fumbi kuti mupukute mandala (osamwa mowa kuti mupewe kuwonongeka kwa zokutira).

Dziwani kufalikira kwa kristalo wa laser (monga Nd:YVO₄) ndikusintha ngati kuli kofunikira.

(2) Kuwongolera dongosolo lozizira

Kukonza kozizira:

Gwiritsani ntchito madzi a deionized + anti-corrosion agent, m'malo mwa miyezi 6 iliyonse.

Yang'anani kutsekedwa kwa chitoliro cha madzi kuti musatayike.

Kuyeretsa Radiator:

Tsukani fumbi pa sinki yotenthetsera yoziziritsidwa ndi mpweya pakatha miyezi itatu iliyonse (kuwonetsetsa kuti kutentha kumatenthedwa).

(3) Kuyendera magetsi ndi makina

Kukhazikika kwamagetsi:

Yang'anirani kusinthasintha kwamagetsi olowera (kufunika <± 5%), tikulimbikitsidwa kuti mukhale ndi UPS voltage stabilizer.

Onani ngati pampu diode (LD) pagalimoto pano ndi yabwinobwino.

Kuwongolera zachilengedwe:

Kutentha kwa ntchito 15 ~ 25 ° C, chinyezi <60%, kupewa condensation.

3. Zolakwa zofala ndi matenda

(1) Mphamvu yotulutsa laser imachepa

Zomwe zingatheke:

Kuwonongeka kwa lens ya kuwala kapena kuwonongeka kwa zokutira

Laser crystal (Nd:YVO₄/YAG) kukalamba kapena matenthedwe a lens

Pampu diode (LD) mphamvu imachepa.

Njira zowunika:

Gwiritsani ntchito mita yamagetsi kuti muwone mphamvu zomwe zimachokera.

Yang'anani njira ya kuwala m'magawo (patulani phokoso la resonant ndikuyesa magwiridwe antchito a gawo limodzi).

(2) Kusakhazikika kwamphamvu kapena kusowa

Zomwe zingatheke:

Q switch (monga acousto-optic modulator AOM) kulephera pagalimoto

Control circuit board (monga FPGA timing board) imawonetsa kusakhazikika

Mphamvu ya module yamagetsi sikwanira.

Njira zowunika:

Gwiritsani ntchito oscilloscope kuti muwone chizindikiro cha Q switch drive.

Onani ngati kubwereza pafupipafupi kupitilira malire.

(3) Alamu ya dongosolo yozizira

Zomwe zingatheke:

Kusakwanira kwa madzi ozizira (kulephera kwa mpope wamadzi kapena kutsekeka kwa mapaipi)

TEC (thermoelectric cooler) kulephera

Kutentha kwa sensor kutentha.

Njira zowunika:

Yang'anani mlingo wa tanki yamadzi ndi fyuluta.

Yesani ngati voteji kudutsa TEC ndi yabwinobwino.

(4) Chipangizocho sichingayambe

Zifukwa zomwe zingatheke:

Mphamvu yayikulu yawonongeka (fuse yaphulitsidwa)

Kutsekeka kwachitetezo kumayambitsidwa (monga chassis sichimatsekedwa)

Sinthani cholakwika cha kulumikizana kwa mapulogalamu.

Njira zowunika:

Yang'anani kulowetsa mphamvu ndi fuse.

Yambitsaninso pulogalamuyo ndikuyikanso dalaivala.

4. Konzani malingaliro ndi njira

(1) Kuthetsa mavuto modular

Gawo la Optical:

Yeretsani kapena sinthani mandala omwe ali ndi kachilombo → Yang'ananinso njira ya kuwala.

Gawo loyang'anira zamagetsi:

Bwezerani bolodi yoyendetsa Q switch yomwe yawonongeka → Sinthani nthawi yake.

Gawo loziziritsa:

Tsegulani mapaipi otsekedwa → Bwezerani pampu yamadzi yolakwika/TEC.

(2) Kulinganiza ndi kuyesa

Kuzindikira kugunda kwa mtima: Gwiritsani ntchito chithunzithunzi chothamanga kwambiri + oscilloscope kuti mutsimikizire kukula kwa kugunda ndi kukhazikika.

Kusanthula kwamtundu wa Beam: Gwiritsani ntchito mita ya M² kuti muwonetsetse kuti mbali ya divergence angle ikugwirizana ndi muyezo.

(3) Malingaliro osankha magawo

Zida zopangira zoyambira (monga ma module a LD ndi masiwichi a Q operekedwa ndi GWU/Laser Components) amakondedwa.

Njira ina: zida zosinthira za gulu lachitatu zomwe zimagwirizana kwambiri (zofananira ndizomwe ziyenera kutsimikiziridwa).

5. Kuteteza dongosolo kukonza

Mwezi uliwonse: mbiri yotulutsa mphamvu ndi mayendedwe amtundu wa pulse.

Miyezi isanu ndi umodzi iliyonse: kuwongolera kwapang'onopang'ono kwa akatswiri akatswiri.

Chaka chilichonse: kuwunika kwathunthu kwa dongosolo lozizirira komanso kukalamba kwa module yamagetsi.

Mapeto

Kupyolera mukukonzekera kokhazikika kwatsiku ndi tsiku + malingaliro okonza modular, moyo wa ma lasers a YLPN ukhoza kukulitsidwa kwambiri ndipo nthawi yopuma imatha kuchepetsedwa. Ngati mukufuna thandizo lakuya, chonde omasuka kulumikizana ndi gulu lathu laukadaulo
