Spectra Physics Quasi-CW UV Laser Gusana

Spectra Physics Quasi Ikomeza Laser (QCW) Vanguard Umwe UV125 ni lazeri ya ultraviolet laser yo gukora neza, ikomatanya ingufu nyinshi nubwiza buhebuje. Ibikurikira nintangiriro yimiterere yabyo, amakosa asanzwe hamwe ningamba zo kubungabunga:

1. Imiterere

Umuyoboro wa Laser resonant

Inkomoko yimbuto: Mubisanzwe diode ipompa Nd: YVO₄ laser kristal itanga 1064nm yumucyo wibanze.

Q-guhinduranya module: Acousto-optique Q-guhinduranya (AO-Q switch) cyangwa electro-optique Q-guhinduranya (EO-Q switch) kugirango itange impiswi ngufi.

Inshuro ebyiri zikubye inshuro: Ihindura 1064nm kuri 532nm (ihuza rya kabiri) ikoresheje kristu ya KTP / LBO, hanyuma ikagera kuri 355nm (icya gatatu gihuza, gisohoka ultraviolet) ikoresheje kristu ya BBO.

Sisitemu yo kuvoma

Laser diode array: Itanga ingufu za pompe kuri Nd: YVO₄ kristal, bisaba kugenzura neza ubushyuhe (gukonjesha TEC).

UV ibisekuruza nibisohoka

Itsinda ridafite umurongo wa kirisiti: BBO cyangwa CLBO kristu ikoreshwa muguhindura UV, igomba guhorana isuku nubushyuhe buhamye.

Indorerwamo yo gusohora indorerwamo: UV irwanya anti-reaction ikoreshwa kugirango igabanye ingufu.

Sisitemu yo gukonjesha

Gukonjesha amazi / gukonjesha ikirere: Komeza ubushyuhe bwumutwe wa laser, kristu na diode (mubisanzwe bisaba ubushyuhe bwamazi bwa ± 0.1 ℃).

Kugenzura no gutanga amashanyarazi

Amashanyarazi menshi yumuriro: Gutwara Q-guhinduranya module na pompe diode.

Sisitemu yo kugenzura: Harimo PLC cyangwa yashyizwemo umugenzuzi, gucunga imbaraga, inshuro, ubugari bwa pulse nibindi bipimo.

Kurinda inzira nziza

Umuyoboro ufunze: Wuzuyemo azote cyangwa umwuka wumye kugirango wirinde urumuri rwa UV gutera kwanduza ibintu byiza (nka kristu ya deliquescence na okiside ya mirror).

2. Amakosa asanzwe nimpamvu zishoboka

Kugabanuka kw'amashanyarazi cyangwa nta bisohoka

Ibintu byanduye byanduye: UV kristu (BBO) cyangwa kwangirika kwindorerwamo.

Q-guhinduranya kunanirwa: AO / EO-Q guhinduranya disiki idasanzwe cyangwa kristu ya offset.

Pompe diode gusaza: ibisohoka imbaraga attenuation cyangwa kunanirwa kugenzura ubushyuhe.

Kwangirika kwubwiza bwibiti (kwiyongera gutandukana, uburyo budasanzwe)

Resonant cavity kudahuza: kunyeganyega kwa mashini bitera lens offset.

Ingaruka ya lisansi yubushyuhe bwa kirisiti: gukonjesha bidahagije cyangwa imbaraga zikabije zitera ihinduka rya kirisiti.

Kugabanya imikorere ya UV ihinduka

Icyiciro cya Crystal gihuza inguni: ihindagurika ry'ubushyuhe cyangwa ubukana bwa mashini.

Imbaraga zidahagije zumucyo wibanze (1064nm / 532nm): ikibazo cyo kugwiza mbere yicyiciro.

Sisitemu yo gutabaza cyangwa guhagarika

Kunanirwa gukonje: ubushyuhe bwamazi buri hejuru cyane, gutemba ntibihagije cyangwa sensor ntisanzwe.

Imbaraga zirenze urugero: voltage ndende module ngufi cyangwa capacitor gusaza.

Guhungabana kwa pulse (guhindagurika kwingufu, inshuro zidasanzwe zisubiramo)

Q guhinduranya ibimenyetso byerekana ibimenyetso: guhuza insinga mbi cyangwa urusaku rwamashanyarazi.

Kugenzura kunanirwa kwa software: gushiraho ikosa cyangwa amakosa ya software.

III. Ingamba zo gufata neza

Igenzura risanzwe

Sukura inzira yumucyo wo hanze (koresha anhydrous ethanol nimpapuro za lens) hanyuma urebe niba hejuru ya kirisiti ya UV yangiritse cyangwa yanduye.

Icyitonderwa: Irinde guhura neza na optique, kandi kristu ya UV (nka BBO) igomba kubikwa muburyo butarimo ubushuhe.

Kubungabunga sisitemu

Buri gihe usimbuze amazi yimana (kugirango wirinde igipimo), urebe niba umuyoboro utemba, kandi usukure umukungugu uri kuri radiator.

Hindura ubushyuhe bwubushyuhe kugirango umenye umuvuduko wo gusubiza sisitemu yo gukonjesha.

Amashanyarazi no kugenzura umuzunguruko

Kurikirana ibisohoka bihamye byamashanyarazi menshi kandi usimbuze ubushobozi bwo gusaza cyangwa ibice byungurura.

Reba umurongo wibanze kugirango ugabanye amashanyarazi.

Calibration kandi Koresha metero yimbaraga hamwe nisesengura ryibiti kugirango uhindure ibisohoka nimbaraga zigihe.

Hindura Q-guhinduranya ibipimo (nkubugari bwa pulse ninshuro zisubiramo) ukoresheje software igenzura.

Kugenzura ibidukikije

Komeza ubushyuhe buhoraho nubushuhe mubikorwa bikora (bisabwa ubushyuhe 22 ± 2 ℃, ubuhehere <50%).

Niba imashini ifunzwe igihe kirekire, birasabwa kuzuza inzira nziza na azote.

Kwandika no gukumira amakosa

Andika kode yo gutabaza hamwe nikosa ryoroshye kugirango byorohereze ikibazo cyihuse (nka software ya Spectra Physics isanzwe itanga amakosa yibibazo).

IV. Kwirinda

Kurinda umutekano: Laser Ultraviolet (355nm) yangiza uruhu n'amaso, kandi ibirahuri bidasanzwe birinda bigomba kwambarwa mugihe cyo gukora.

Kubungabunga umwuga: Guhuza Crystal guhuza na resonant cavity debugging bigomba gukorwa nuwabikoze cyangwa injeniyeri zemewe kugirango birinde kwishira.

Gucunga ibice byabigenewe: Bika ibice byoroshye (nka O-impeta, diode ya pompe, Q-uhindura kristu).

Niba hari izindi nkunga ya tekiniki isabwa, birasabwa kuvugana nitsinda ryacu rya tekiniki hanyuma tugatanga numero ya laser numero yamakosa kugirango tubone ibisubizo bigamije.
