Spectra Physics Quasi-CW UV Laser Repair

Spectra Physics Quasi Continuous Laser (QCW) Vanguard One UV125 waa laysar ultraviolet ah oo joogto ah oo loogu talagalay farsamaynta saxda ah, isku darka soo saarista koronto sare iyo tayada alwaax aad u fiican. Kuwa soo socda waa hordhac qaab-dhismeedkeeda, khaladaadka guud iyo tallaabooyinka dayactirka:

1. Qaab dhismeedka

Laser godka resonant

Ilaha abuur: Sida caadiga ah diode-pumped Nd:YVO₄ laser crystal kaas oo soo saara 1064nm iftiin soo noqnoqda aasaasiga ah.

Qalabka Q-bedelashada: Acousto-optic Q-bedelida (Shidaalka AO-Q) ama electro-optic Q-switching (EO-Q) si loo dhaliyo garaacyada gaaban.

Qaabka labanlaabka soo noqnoqda: Wuxuu u beddelaa 1064nm ilaa 532nm (labaad iswaafajin) iyada oo loo marayo KTP/LBO crystal, ka dibna 355nm (sadexda harmonic, soosaarka ultraviolet) iyada oo loo marayo crystal BBO.

Nidaamka bamgareynta

Iskudubbaridka diode laser: Waxay siisaa tamarta bamka ee Nd:YVO₄ crystal, u baahan xakamaynta heerkulka saxda ah (TEC qaboojinta).

Jiilka UV iyo wax soo saarka

Kooxda crystal-ka aan tooska ahayn: BBO ama CLBO crystal waxa loo isticmaalaa beddelka UV, kaas oo u baahan in la nadiifiyo oo heerkulku xasilo.

Muraayada isku-xidhka wax-soo-saarka: Daahan ka-hortagga-milicsiga UV ayaa la mariyaa si loo yareeyo khasaaraha tamarta.

Nidaamka qaboojinta

Qalabka qaboojinta biyaha / qaboojinta hawada: Ilaali xasiloonida heerkulka madaxa laysarka, crystal iyo diode (badanaa waxay u baahan tahay saxnaanta heerkulka biyaha ± 0.1 ℃).

Xakamaynta iyo korontada

Koronto koronto oo aad u sareysa: Drive Q-switching module iyo diode bamka.

Nidaamka xakamaynta: oo ay ku jiraan PLC ama kontaroolaha guntanka ah, maamula awooda, inta jeer, ballaca garaaca wadnaha iyo cabirrada kale.

Ilaalinta waddooyinka indhaha

dalool xidhan: Ka buuxsamay nitrogen ama hawo engegan si looga hortago iftiinka UV inuu keeno wasakhaynta qaybaha indhaha (sida qallafsanaanta crystal iyo oksaydhka muraayadda).

2. Cilladaha guud iyo sababaha suurtagalka ah

Korontadu hoos u dhacdo ama wax soo saar la'aan

Wasakhaynta qaybaha indhaha: UV crystal (BBO) ama dhaawac dahaarka muraayadda.

Beddelaadda Q-guuldarada: AO/EO-Q beddelka waditaanka cillad-darrada ama ka-saarista crystal-ka.

Duqnimada diode ee bamka: hoos u dhigista awoodda wax soo saarka ama xakamaynta heerkulka.

Hoos-u-dhac tayada alwaax ah (kordhinta xagasha kala duwanaanshaha, qaab aan caadi ahayn)

Qalafsanaan la'aanta godka resonant: gariirka farsamada ayaa sababa dib u dhigista muraayadda.

Saamaynta lenska kulaylka kristal: qaboojin ku filan ama awoodda xad dhaafka ah waxay sababtaa qallafsanaanta crystal.

Waxtarka beddelka UV oo yaraaday

xagal u dhigma wejiga Crystal: isbeddelka heerkulka ama dabacsanaanta farsamada.

Awoodda aan ku filnayn ee iftiinka soo noqnoqda ee aasaasiga ah (1064nm/532nm): dhibaatada isku dhufashada marxaladda kahor.

alaarmiga nidaamka ama xidhidh

Qaboojin la'aanta: heerkulka biyuhu aad buu u sarreeyaa, qulqulitaanku kuma filna ama dareemaha ayaa ah mid aan caadi ahayn.

Kordhinta awoodda: moduleka tamarta sare ee wareegga gaaban ama gabowga capacitor.

Xasilooni la'aanta garaaca wadnaha (isbedelka tamarta, soo noqnoqoshada aan caadiga ahayn)

Fargelinta calaamadda wadista beddelka: xidhiidhka fiilada oo liita ama buuqa sahayda korontada.

Xakamaynta fashilka sooftiweerka: cilad dejinta halbeegyada ama bug firmware.

III. Tallaabooyinka dayactirka

Kormeerka indhaha oo joogto ah

Nadiifi muraayada laydhka dibadda (isticmaal ethanol anhydrous iyo warqad lens) oo hubi in dusha sare ee crystal UV uu dhaawacmay ama wasakhaysan yahay.

Fiiro gaar ah: Ka fogow taabashada tooska ah ee daahan indhaha, iyo kiristaalo UV (sida BBO) waxay u baahan yihiin in lagu kaydiyo hab aan qoyaanka ilaalinayn.

Dayactirka nidaamka qaboojinta

Si joogto ah u beddel biyaha deionized (si aad uga hortagto miisaanka), hubi in dhuumuhu soo daadanayaan, oo nadiifi siigada hiitarka.

Kala beddel dareenka heerkulka si aad u hubiso xawaaraha jawaabta nidaamka qaboojinta.

Korontada iyo kormeerka wareegga

La soco xasiloonida wax-soo-saarka tamarta korantada-sare ee tamarta oo beddel capacitors-ka gabowga ama qaybaha filter-ka.

Fiiri xariiqda dhulka si aad u yareyso faragelinta korantada.

Qalabaynta iyo Isticmaal mitirka korantada iyo falanqeeyaha iftiinka si aad u qiyaasto awoodda wax soo saarka iyo qaabka booska si joogto ah.

Wanaaji cabbirada Q-beddelka (sida ballaca garaaca wadnaha iyo soo noqnoqda) iyada oo loo marayo software-ka kontoroolka.

Xakamaynta deegaanka

Ku ilaali heerkulka iyo qoyaanka joogtada ah ee deegaanka shaqada (heerkulka lagu taliyay 22± 2℃, qoyaan <50%).

Haddii mashiinka la xiro muddo dheer, waxaa lagu talinayaa in lagu buuxiyo waddada indhaha ee nitrogen.

Duubista qaladka iyo ka hortagga

Diiwaangeli nambarka digniinta iyo ifafaalaha qaladka si loo fududeeyo goobta dhibka degdega ah (sida Spectra Physics software inta badan waxay bixisaa diiwaannada khaladaadka).

IV. Ka taxadaritaan

Ilaalinta badbaadada: Laysarka ultraviolet (355nm) wuxuu dhib u leeyahay maqaarka iyo indhaha, waana in muraayado ilaalin gaar ah la gashado inta lagu jiro hawlgalka.

Dayactirka xirfadlaha ah: Isku toosinta kristanta iyo dib u hagaajinta godka resonant waa in ay sameeyaan soo saaraha ama injineerada shahaado haysta si ay uga fogaadaan in ay is-kala furfuraan.

Maareynta Qaybaha Fudud: Kaydi qaybaha nugul (sida O-rings, diodes bamka, kiristaalo Q-switch).

Haddii taageero farsamo oo dheeraad ah loo baahan yahay, waxaa lagu talinayaa in la xiriiro kooxdayada farsamada iyo bixinta lambarka taxanaha leysarka iyo faahfaahinta cilladda si loo helo xal la beegsaday.
