Toptica inshuro imwe ya semiconductor laser gusana

TopWica ya TopWave 405 ni lazeri yuzuye ya semiconductor yumurongo wa lazeri ifite uburebure bwa metero 405 nm (hafi-UV), isuzumwa cyane mubice bya bioimaging (nka microscopi ya STED), urumuri rworoheje, kwant optique, holography na spécroscopi neza. Ibyiza byingenzi byingenzi ni umurongo mugari (<1 MHz), uburebure bwumurambararo mwinshi (<1 pm) nibiranga urusaku ruke, bikwiranye nubushakashatsi bwa siyansi hamwe ninganda zikenewe cyane kugirango imikorere ya laser ikorwe.

2. Ibiranga

Ibisohoka-inshuro imwe

Kwemeza ** Igishushanyo mbonera cyo hanze cya Laser (ECDL) ** igishushanyo, cyahujwe no gushimira kugirango tumenye igitekerezo kimwe cyimikorere ya module ikora, cyemeza umurongo muto kandi urusaku ruke.

Umuhengeri muremure

Yubatswe muri PZT (piezoelectric ceramic) telesikope no kugenzura ubushyuhe (TEC) kugirango ugere kumuraba wumuraba no guhagarara neza.

Urusaku ruke

Gukoresha urusaku ruke rwumuvuduko hamwe nubuhanga bukoresha tekinoroji (nka Pound-Drever-Hall funga inshuro) kugirango ugabanye ubukana bwurusaku hamwe ninshuro.

Guhinduka

Muguhindura inguni cyangwa impinduka zubu / ubushyuhe, telesikopi ikomeza murwego rwa GHz iragerwaho, ikwiranye nubushakashatsi bwo gusikana.

III. Imiterere

Imiterere yibanze ya Top Wave 405 irashobora kugabanywa mubice bikurikira byingenzi:

1. Gukwirakwiza Laser (LD)

405 nm ya semiconductor laser chip (nka GaN ishingiye kuri laser diode) nkisoko yambere yumucyo.

Igenzura ry'ubushyuhe bwa TEC ryemeza ko ikwirakwizwa rikora ku bushyuhe bwiza (ubusanzwe ~ 25 ° C) kugirango wirinde intera ndende.

2. Sisitemu yo gutanga ibitekerezo hanze

Gusya neza (Ubwoko bwa Littrow cyangwa Littman-Metcalf imiterere): bikoreshwa muguhitamo uburebure bwumurongo no gutanga ibitekerezo inshuro imwe.

PZT ikora: gusya inguni kugirango ugere kuri fibre ndende.

3. Kwigunga neza no kugenzura uburyo

Faraday izigunga: irinda kugaruka kugaruka kutabangamira ituze rya laser.

Imbonerahamwe ihuza uburyo: itunganya ubwiza bwibiti kandi ikemeza uburyo bwa TEM00 busohoka.

4. Sisitemu yo kugenzura ibikoresho bya elegitoroniki

Urusaku ruke rwumuvuduko: rutanga LD ihamye.

PID igenzura ubushyuhe bwumuzingi: hindura neza gukwirakwiza laser hamwe nubushuhe.

Module yo gufunga inshuro (kubishaka): nka PDH yumurongo uhoraho, ikoreshwa kuri ultra-تارufi ya linewidth ya porogaramu.

5. Gusohora hamwe no gukurikirana

Igice cyerekana indorerwamo: gukuramo laser mugihe ugumana ibitekerezo byimbere.

Igenzura rya Photodiode (PD): igihe nyacyo cyo kumenya imbaraga za laser nuburyo butajegajega.

IV. Amakosa asanzwe hamwe nibitekerezo byo kubungabunga

1. Nta bisohoka bya laser cyangwa imbaraga zigabanuka

Impamvu zishoboka:

Kwangirika kwa Laser (ESD gusenyuka cyangwa gusaza).

Kunanirwa kwiki gihe (nkibyangiritse byamashanyarazi).

Gushimira gusana (kunyeganyeza imashini bitera kunanirwa ibitekerezo).

Ibitekerezo byo gufata neza:

Reba niba ibiyobora bigenda bisanzwe (reba intoki igenamigambi).

Koresha metero y'amashanyarazi kugirango umenye niba LD itanga urumuri (birakenewe kurinda umutekano).

Ongera uhindure inguni kugirango ushishoze neza.

2. Umuhengeri udahungabana cyangwa uburyo bwo gutega

Impamvu zishoboka:

Kunanirwa kugenzura ubushyuhe (gutsindwa kwa TEC cyangwa thermistor).

Kurekura imashini (PZT cyangwa gusya ntabwo byashizweho neza).

Kunyeganyega hanze cyangwa guhungabana kurangiza.

Ibitekerezo byo gufata neza:

Reba niba TEC yashyizeho ubushyuhe bujyanye nubushyuhe nyabwo.

Ibikoresho bya kolagen optique kugirango bigabanye ihindagurika ryibidukikije.

Koresha metero ndende kugirango ukurikirane kandi wongere umenye niba ari ngombwa.

3. Ntibishobora gushiraho urwego rwa telesikope cyangwa telesikope

Impamvu zishoboka:

Umuvuduko wa PZT udahagije (gutsindira ibizunguruka).

Gushimangira imashini (gusiga amavuta adahagije cyangwa guhindura imiterere).

V. Ingamba zo kubungabunga ibidukikije

Buri gihe usukure ibikoresho bya optique

Koresha Ethanol ya anhydrous na ultra-isukuye ipamba kugirango usukure indorerwamo yo gusohora no gusohora kugirango wirinde kugira ingaruka muburyo butajegajega.

Kugenzura no kugenzura ubushyuhe

Menya neza ko TEC idafite ivumbi kandi umufana akora bisanzwe.

Kurinda anti-static (ESD)

Wambare igitoki kirwanya static mugihe cyo gukora kugirango wirinde kwangirika.

Kugenzura ibidukikije

Komeza ubushyuhe buhoraho (± 1 ° C) hamwe n’ibidukikije bihindagurika, kandi ukoreshe urubuga rwo kwigunga igihe bibaye ngombwa.

Gahunda isanzwe

Koresha uburebure bwa metero na metero yimbaraga kugirango utegure ibisohoka kugirango umenye neza igihe kirekire.

VI. Umwanzuro

TopWave 405 ya lazeri imwe imwe, hamwe no guhagarara kwayo hamwe no kugabanya umurongo wa interineti, ni amahitamo meza kubushakashatsi bwa siyansi no gukoresha inganda zo mu rwego rwo hejuru. Kubungabunga buri gihe, kugenzura ibidukikije nuburyo bukwiye bwo gusuzuma amakosa nurufunguzo rwo kwemeza imikorere yigihe kirekire yizewe. Kubibazo bigoye (nko kunanirwa gufunga inshuro cyangwa kwangirika kwa laser), birasabwa kuvugana nitsinda ryacu tekinike kugirango twirinde kwangirika kwatewe no gusenya terefone.
