Imibuzo Eminye Ebalulekile Nge-Erbium Glass Laser

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

Umehluko phakathi kobubanzi be-pulse (ns) kanye nobubanzi be-pulse (ms) ungokulandelayo: i-ns ibhekisela esikhathini sokushaya kokukhanya, i-ms ibhekisela esikhathini sokushaya kogesi ngesikhathi sokuphakelwa kwamandla.

2. Ingabe umshayeli we-laser udinga ukunikeza i-trigger pulse emfushane engu-3-6ns, noma ingabe i-module ingakwazi ukuyisingatha yodwa?

Akukho module yangaphandle yokuguqula edingekayo; uma nje kukhona i-pulse kububanzi be-ms, imodule ingakhiqiza i-ns light pulse ngokwayo.

3. Kungenzeka yini ukwandisa izinga lokushisa lokusebenza lifike ku-85°C?

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

4. Ingabe kukhona umgodi ngemuva kwelensi ogcwele i-nitrogen noma ezinye izinto ukuqinisekisa ukuthi inkungu ayakheki ngaphakathi emazingeni okushisa aphansi kakhulu?

Uhlelo lwenzelwe ukusetshenziswa emazingeni okushisa aphansi njengo-40°C nangaphezulu, futhi ilensi enweba imisebe, esebenza njengefasitela elibonakalayo, ngeke igcwale inkungu. Umgodi uvaliwe, futhi imikhiqizo yethu igcwele i-nitrogen ngemuva kwelensi, okuqinisekisa ukuthi ilensi ingaphakathi kwendawo yegesi engangeni, okugcina i-laser isendaweni ehlanzekile.

5. Iyini indlela yokunciphisa ukucindezeleka?

Sisebenzise ingilazi ye-Er-Yb njengendlela esebenzayo.

6. I-lasing medium ipompiwa kanjani?

Kwasetshenziswa i-compact chirp ku-submount packed diode laser ukuze kupompe i-active medium ngendlela ende.

7. Yakhiwa kanjani imbobo yelaser?

Umgodi we-laser wakhiwa ngengilazi ye-Er-Yb eboshwe kanye ne-coupler yokuphuma.

8. Ufinyelela kanjani ekuhlukaneni okungu-0.5 mrad? Ungakwenza okuncane?

Uhlelo lokukhulisa imisebe kanye nokuhlanganisa olufakiwe ngaphakathi kwedivayisi yelaser luyakwazi ukucindezela i-engeli yokwehlukana kwemisebe ibe ngaphansi kuka-0.5-0.6mrad.

9. Izinto esizikhathalela kakhulu zihlobene nezikhathi zokukhuphuka nokuwa, zinikeza i-laser pulse emfushane kakhulu. Imininingwane ikhombisa isidingo se-2V/7A. Ingabe lokhu kusho ukuthi ugesi kumele ulethe la manani ngaphakathi kwama-3-6ns, noma kukhona iphampu yokushaja ehlanganisiwe kumojuli?

I-3-6n ichaza ubude be-pulse yomsebe wokukhipha i-laser kunobude besikhathi sokunikezwa kwamandla angaphandle. Ukunikezwa kwamandla angaphandle kudinga nje ukuqinisekisa ukuthi:

① Ukufakwa kwesignali yegagasi lesikwele;

② Ubude besignali yegagasi lesikwele bungama-millisecond.

10. Yiziphi izici ezithinta ukuzinza kwamandla?

Ukuzinza kwamandla kubhekisela ekhonweni le-laser lokugcina amandla okukhishwa kokukhanya angaguquki isikhathi eside sokusebenza. Izici ezithinta ukuzinza kwamandla zifaka:

① Ukwehluka kwezinga lokushisa

② Ukuguquguquka kwamandla kagesi nge-laser

③ Ukuguga nokungcoliswa kwezingxenye ze-optical

④ Ukuqina komthombo wephampu

11. Kuyini i-TIA?

I-TIA imele i-“Transimpedance Amplifier,” okuyi-amplifier eguqula izimpawu zamanje zibe izimpawu zamandla kagesi. I-TIA isetshenziswa kakhulu ukukhulisa izimpawu zamanje ezibuthakathaka ezikhiqizwa ama-photodiode ukuze kuqhutshekwe kucutshungulwe futhi kuhlaziywe. Ezinhlelweni ze-laser, ivame ukusetshenziswa kanye ne-feedback diode ukuze kuzinziswe amandla okukhipha i-laser.

12. Isakhiwo kanye nesimiso se-laser yengilazi ye-erbium

Njengoba kuboniswe kumdwebo ongezansi
