Spectra Physics Quasi-CW UV Laser kukonza

Spectra Physics Quasi Continuous Laser (QCW) Vanguard One UV125 ndi laser yopitilira ultraviolet yopangira makina olondola, kuphatikiza kutulutsa kwamphamvu kwambiri komanso mtengo wabwino kwambiri wa mtengo. Zotsatirazi ndizomwe zimayambira pamapangidwe ake, zolakwika zomwe zimachitika kawirikawiri ndi njira zokonzera:

1. Kapangidwe

Laser resonant cavity

Gwero la Mbewu: Nthawi zambiri ndi diode-pumped Nd:YVO₄ laser crystal yomwe imapanga 1064nm Basic frequency light.

Q-switching module: Acousto-optic Q-switching (AO-Q switch) kapena electro-optic Q-switching (EO-Q switch) popanga ma pulse aafupi.

Module yowirikiza kawiri: Imasintha 1064nm kukhala 532nm (yachiwiri yolumikizana) kudzera mu krustalo ya KTP/LBO, kenako kupita ku 355nm (yachitatu ya harmonic, kutulutsa kwa ultraviolet) kudzera mu galasi la BBO.

Pampu dongosolo

Laser diode array: Amapereka mphamvu ya mpope ya Nd:YVO₄ crystal, yomwe imafunika kuwongolera kutentha koyenera (TEC yozizira).

Kutulutsa kwa UV ndi zotuluka

Gulu la kristalo lopanda mzere: BBO kapena CLBO crystal imagwiritsidwa ntchito kutembenuka kwa UV, komwe kumayenera kukhala koyera komanso kutentha kokhazikika.

Kalasi yolumikizira yotulutsa: Chophimba cha UV anti-reflection chimayikidwa kuti muchepetse kutaya mphamvu.

Njira yozizira

Kuziziritsa madzi / mpweya kuzirala gawo: Pitirizani kukhazikika kutentha kwa laser mutu, galasi ndi diode (nthawi zambiri amafuna madzi kutentha molondola ± 0.1 ℃).

Kuwongolera ndi magetsi

Mphamvu yamagetsi apamwamba: Thamangitsani gawo losinthira la Q ndi diode yapampu.

Dongosolo loyang'anira: Kuphatikiza PLC kapena chowongolera chophatikizidwa, yendetsani mphamvu, pafupipafupi, kugunda m'lifupi ndi magawo ena.

Chitetezo cha njira ya Optical

Pakhomo lomata: Lodzazidwa ndi nayitrogeni kapena mpweya wouma kuteteza kuwala kwa UV kuti zisapangitse kuipitsidwa ndi zinthu (monga crystal deliquescence ndi mirror oxidation).

2. Zolakwa zofala ndi zomwe zingayambitse

Kutsika kwamphamvu kapena kusatulutsa

Kuipitsidwa kwa chigawo cha Optical: UV crystal (BBO) kapena kuwonongeka kwa galasi.

Kulephera kwa Q-switching: AO/EO-Q switch drive abnormality kapena crystal offset.

Kukalamba kwapampu ya diode: kuchepetsa mphamvu zotulutsa kapena kulephera kuwongolera kutentha.

Kuwonongeka kwa mtengo wamtengo (kuchuluka kosiyana kosiyana, mawonekedwe achilendo)

Kusokonekera kwapang'onopang'ono: kugwedezeka kwamakina kumayambitsa magalasi.

Crystal thermal lens effect: kuziziritsa kosakwanira kapena mphamvu zochulukirapo kumayambitsa kusinthika kwa kristalo.

Kuchepetsa kutembenuka kwa UV

Crystal gawo lofananira angle offset: kusinthasintha kwa kutentha kapena kutayikira kwamakina.

Kusakwanira kwa mphamvu zowunikira pafupipafupi (1064nm/532nm): vuto lochulutsa ma frequency a pre-stage.

Alamu yadongosolo kapena kutseka

Kulephera kwa kuziziritsa: kutentha kwa madzi ndikokwera kwambiri, kutuluka sikukwanira kapena sensa ndi yachilendo.

Kuchulukitsitsa kwamphamvu: gawo lalitali lamagetsi lalifupi kapena kukalamba kwa capacitor.

Kusakhazikika kwa pulse (kusinthasintha kwa mphamvu, kubwereza kwachilendo)

Kusokoneza kwa siginecha ya Q switch: kulumikizidwa kwa chingwe kapena phokoso lamagetsi.

Yang'anirani kulephera kwa mapulogalamu: cholakwika chokhazikitsa parameter kapena cholakwika cha firmware.

III. Njira zosamalira

Kuyang'ana kwa maso nthawi zonse

Yeretsani ma lens akunja (gwiritsani ntchito ethanol ya anhydrous ndi pepala la lens) ndikuwona ngati pamwamba pa galasi la UV lawonongeka kapena laipitsidwa.

Zindikirani: Pewani kukhudzana mwachindunji ndi zokutira zowoneka bwino, ndipo makristasi a UV (monga BBO) ayenera kusungidwa m'njira yoteteza chinyezi.

Kukonzekera dongosolo lozizira

Nthawi zonse sinthani madzi opanda madzi (kuteteza sikelo), fufuzani ngati payipi yatuluka, ndikutsuka fumbi pa radiator.

Sanjani sensa ya kutentha kuti muwonetsetse kuthamanga kwa makina ozizira.

Kupereka mphamvu ndi kuyendera dera

Yang'anirani kukhazikika kwamagetsi amagetsi apamwamba kwambiri ndikusintha ma capacitor okalamba kapena zida zosefera.

Yang'anani mzere woyambira kuti muchepetse kusokoneza kwa electromagnetic.

Calibration ndi Gwiritsirani ntchito mita yamagetsi ndi chowunikira chamtengo kuti muwongolere mphamvu zomwe zimachokera komanso mawonekedwe owonekera pafupipafupi.

Konzani magawo a Q-switching (monga kuchuluka kwa kugunda ndi kubwereza pafupipafupi) kudzera pamapulogalamu owongolera.

Kuwongolera chilengedwe

Sungani kutentha ndi chinyezi nthawi zonse m'malo ogwirira ntchito (kutentha kovomerezeka 22 ± 2 ℃, chinyezi <50%).

Ngati makinawo atsekedwa kwa nthawi yayitali, tikulimbikitsidwa kuti mudzaze njira ya kuwala ndi nayitrogeni.

Kulemba zolakwika ndi kupewa

Jambulani nambala ya alamu ndi cholakwika kuti muthandizire komwe kuli vuto mwachangu (monga pulogalamu ya Spectra Physics nthawi zambiri imapereka zolemba zolakwika).

IV. Kusamalitsa

Chitetezo chachitetezo: Laser ya Ultraviolet (355nm) ndi yowopsa pakhungu ndi maso, ndipo magalasi oteteza apadera ayenera kuvalidwa panthawi yogwira ntchito.

Kukonza mwaukadaulo: Kuyanjanitsa kwa kristalo ndi kukonza zolakwika zapabowo kuyenera kuchitidwa ndi wopanga kapena mainjiniya ovomerezeka kuti apewe kudzipatula.

Kasamalidwe ka zida zosinthira: Sungani magawo omwe ali pachiwopsezo (monga mphete za O, ma diode apampu, makristalo a Q-switch).

Ngati thandizo lina laukadaulo likufunika, tikulimbikitsidwa kuti mulumikizane ndi gulu lathu laukadaulo ndikupereka nambala ya serial ya laser ndi zolakwika kuti mupeze mayankho omwe mukufuna.
