Imibuzo Ethile Enentsingiselo malunga ne-Erbium Glass Laser

1. Yintoni umahluko phakathi kobubanzi be-pulse (ns) kunye nobubanzi be-pulse (ms)?

Umahluko phakathi kobubanzi be-pulse (ns) kunye nobubanzi be-pulse (ms) ngolu hlobo lulandelayo: i-ns ibhekisa kubude be-pulse yokukhanya, i-ms ibhekisa kubude be-pulse yombane ngexesha lokunikezelwa kombane.

2. Ngaba umqhubi welaser kufuneka anike i-short trigger pulse ye-3-6ns, okanye ngaba imodyuli ingakwazi ukuyiphatha yodwa?

Akukho module yangaphandle efunekayo; lo gama nje kukho i-pulse kuluhlu lwe-ms, i-module ingenza i-ns light pulse ngokwayo.

3. Ngaba kunokwenzeka ukwandisa ubushushu bokusebenza ukuya kuma-85°C?

Ububanzi bobushushu abunakufikelela kwi-85°C; ubushushu obuphezulu esibuvavanyeyo buyi--40°C ukuya kwi-70°C.

4. Ngaba kukho umngxuma emva kwelensi ozaliswe yinitrogen okanye ezinye izinto ukuqinisekisa ukuba inkungu ayibumbi ngaphakathi kumaqondo obushushu aphantsi kakhulu?

Le nkqubo yenzelwe ukusetyenziswa kumaqondo obushushu aphantsi njenge-40°C nangaphezulu, kwaye ilensi ekhulisa imisebe, esebenza njengefestile ye-optical, ayizukugquma. Umngxuma uvaliwe, kwaye iimveliso zethu zizaliswe yi-nitrogen emva kwelensi, ukuqinisekisa ukuba ilensi ikwindawo enegesi engangeniyo, igcina i-laser ikwimo ecocekileyo.

5. Yintoni indlela yokunciphisa ubushushu?

Sisebenzise iglasi ye-Er-Yb njengendlela esebenzayo.

6. Ipompelwa njani i-lasing medium?

I-compact chirp kwi-submount packed diode laser isetyenzisiwe ukupompa i-active medium ngobude.

7. Yenziwa njani i-laser cavity?

I-laser cavity yenziwe ngeglasi ye-Er-Yb egqunywe nge-coupler kunye ne-output coupler.

8. Ufikelela njani kwi-0.5 mrad divergency? Ngaba ungenza okuncinci?

Inkqubo yokwandisa imisebe kunye nenkqubo ye-collimation efakiweyo ngaphakathi kwesixhobo se-laser iyakwazi ukunciphisa i-engile yokwahlukana komsebe ukuya kuthi ga kwi-0.5-0.6mrad.

9. Iingxaki zethu eziphambili zinxulumene namaxesha okunyuka nokuwa, zinika i-laser pulse emfutshane kakhulu. Ingcaciso ibonisa imfuneko ye-2V/7A. Ngaba oku kuthetha ukuba umbane kufuneka unikeze la maxabiso ngaphakathi kwe-3-6ns, okanye kukho ipompo yokutshaja edityanisiweyo kwimodyuli?

I-3-6n ichaza ubude be-pulse yomqadi wokukhupha i-laser kunobude bexesha lombane wangaphandle. Umbane wangaphandle ufuna nje ukuqinisekisa oku:

① Ukufakwa kwesignali yewave yesikwere;

② Ubude besignali yewave yesikwere bukwii-milliseconds.

10. Ziziphi izinto ezichaphazela uzinzo lwamandla?

Uzinzo lwamandla lubhekisa kubuchule be-laser bokugcina amandla ombane aphumayo angaguquguqukiyo ngexesha elide lokusebenza. Izinto ezichaphazela uzinzo lwamandla ziquka:

① Utshintsho lobushushu

② Ukuguquguquka kwamandla elaser

③ Ukwaluphala kunye nongcoliseko lwezixhobo ze-optical

④ Uzinzo lomthombo wepompo

11. Yintoni i-TIA?

I-TIA imele "i-Transimpedance Amplifier," eyi-amplifier eguqula imiqondiso yangoku ibe yimiqondiso ye-voltage. I-TIA isetyenziselwa ikakhulu ukukhulisa imiqondiso yangoku ebuthathaka eveliswa yi-photodiodes ukuze iqhubeke nokucutshungulwa kunye nohlalutyo. Kwiinkqubo ze-laser, idla ngokusetyenziswa kunye ne-feedback diode ukuzinzisa amandla okukhupha i-laser.

12. Ulwakhiwo kunye nomgaqo we-laser yeglasi ye-erbium

Njengoko kubonisiwe kumzobo ongezantsi
