Eminye Imibuzo Enenjongo Nge-Erbium Glass Laser

1. Uyini umehluko phakathi kobubanzi bokushaya kwenhliziyo (ns) nobubanzi be-pulse (ms)?

Umehluko phakathi kobubanzi be-pulse (ns) kanye nobubanzi be-pulse (ms) kanje: i-ns isho ubude besikhathi sokushaya kokukhanya, i-ms isho ubude besikhathi sokushaya kukagesi ngesikhathi sokunikezwa kwamandla.

2. Ingabe umshayeli we-laser udinga ukuhlinzeka nge-trigger emfushane ye-3-6ns, noma imojula ingakwazi ukuyiphatha ngokwayo?

Ayikho imojula yokushintshashintsha yangaphandle edingekayo; inqobo nje uma kukhona ukushaya kwenhliziyo ebangeni le-ms, imojuli ingakhiqiza i-ns light pulse ngokwayo.

3. Kungenzeka yini ukwelula izinga lokushisa lokusebenza libe ngu-85 ° C?

Izinga lokushisa alikwazi ukufinyelela ku-85 ° C; izinga lokushisa eliphezulu esilihlolile lingu -40°C kuya ku-70°C.

4. Ingabe kunesikhala ngemva kwelensi egcwele i-nitrogen noma ezinye izinto ukuze kuqinisekiswe ukuthi inkungu ayenzeki ngaphakathi emazingeni okushisa aphansi kakhulu?

Isistimu yakhelwe ukusetshenziswa emazingeni okushisa afinyelela ku -40°C nangaphezulu, futhi ilensi enweba uthango, esebenza njengefasitela elibonakalayo, ngeke igcwale inkungu. Imbobo ivaliwe, futhi imikhiqizo yethu igcwele i-nitrogen ngemuva kwelensi, iqinisekisa ukuthi ilensi ingaphakathi kwendawo yegesi engasebenzi, okugcina i-laser isendaweni ehlanzekile.

5. Iyini i-lasing medium?

Sisebenzise ingilazi ye-Er-Yb njengendawo esebenzayo.

6. I-lasing medium impontshwa kanjani?

Ukutshiyoza okuhlangene ku-submount packed diode laser kwasetshenziswa ukupompa okuphakathi nendawo okusebenzayo ngobude.

7. Yakhiwa kanjani i-laser cavity?

I-laser cavity yakhiwa ingilazi ye-Er-Yb eboshwe kanye ne-coupler ephumayo.

8. Uyithola kanjani i-0.5 mrad divergency? Ungakwazi ukwenza okuncane?

Uhlelo oluhlanganisiwe lokunwetshwa kwe-beam kanye ne-collimation ngaphakathi kwedivayisi ye-laser luyakwazi ukuminyanisa i-engeli ehlukile ye-beam ibe ngaphansi kuka-0.5-0.6mrad.

9. Izinto ezisikhathazayo eziyinhloko zihlobene nezikhathi zokukhuphuka nokuwa, nikeza i-laser pulse emfushane kakhulu. Ukucaciswa kukhombisa imfuneko ye-2V/7A. Ingabe lokhu kusho ukuthi ukunikezwa kwamandla kufanele kulethe lawa manani phakathi kuka-3-6ns, noma kukhona iphampu yokushaja ehlanganiswe kumojula?

I-3-6n ichaza ubude besikhathi sokushaya kwe-laser okukhiphayo kunesikhathi sokunikezwa kwamandla kwangaphandle. Ukunikezwa kwamandla kwangaphandle kudinga nje ukuqinisekisa:

① Okokufaka kwesiginali yegagasi lesikwele;

② Ubude besikhathi sesiginali yegagasi yesikwele bungama-millisecond.

10. Yiziphi izici ezithinta ukuqina kwamandla?

Ukuzinza kwamandla kusho ikhono le-laser ukugcina amandla e-beam angaguquguquki esikhathini eside sokusebenza. Izinto ezithinta ukuqina kwamandla zihlanganisa:

① Ukwehluka kwezinga lokushisa

② Ukushintshashintsha kwamandla e-laser

③ Ukuguga nokungcoliswa kwezingxenye ezibonakalayo

④ Ukuzinza komthombo wephampu

11. Yini i-TIA?

I-TIA imele “i-Transimpedance Amplifier,” okuyi-amplifier eguqula amasignali amanje abe amasignali kagesi. I-TIA isetshenziselwa ikakhulukazi ukukhulisa amasiginali amanje abuthakathaka akhiqizwa ama-photodiode ukuze kuqhutshekwe nokucubungula nokuhlaziya. Ezinhlelweni ze-laser, ngokuvamile isetshenziswa kanye ne-diode yempendulo ukuzinzisa amandla okukhipha i-laser.

12. Isakhiwo kanye nomgomo we-erbium glass laser

Njengoba kukhonjisiwe kumdwebo ongezansi
