Eminye imibuzo enentsingiselo malunga ne-Erbium Glass Laser

1. Uthini 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 ibhekisela kwixesha le-pulse yokukhanya, i-ms ibhekisela kwixesha le-pulse yombane ngexesha lonikezelo lwamandla.

2. Ngaba umqhubi we-laser kufuneka anikeze i-pulse emfutshane ye-trigger ye-3-6ns, okanye imodyuli ingakwazi ukuyiphatha ngokwayo?

Akukho modyuli yangaphandle efunekayo; okoko kukho i-pulse kuluhlu lwe-ms, imodyuli inokuvelisa i-ns light pulse ngokwayo.

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

Uluhlu lweqondo lokushisa alukwazi ukufikelela kwi-85 ° C; ubushushu obuphezulu esibuvavanyileyo yi--40°C ukuya kuma-70°C.

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

Inkqubo yenzelwe ukusetyenziswa kumaqondo okushisa aphantsi -40 ° C nangaphezulu, kwaye i-lens yokwandisa i-beam, esebenza njengefestile ye-optical, ayiyi kubamba inkungu. Umgodlo utywinwe, kwaye iimveliso zethu zizaliswe yinitrogen emva kwelensi, ziqinisekisa ukuba ilensi ingaphakathi kwendawo yegesi engasebenziyo, igcina i-laser kwindawo ecocekileyo.

5. Yintoni i-lasing medium?

Sisebenzise iglasi ye-Er-Yb njengendawo esebenzayo.

6. Ingaba i-lasing medium impontshwa njani?

I-compact chirp kwi-submount packed diode laser yasetyenziselwa ukumpompa okuphakathi okusebenzayo.

7. Yenziwa njani i-laser cavity?

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

8. Ufikelela njani kwi-0.5 mrad divergency? Ungenza encinci?

Inkqubo yokwandiswa kwe-beam edibeneyo kunye ne-collimation ngaphakathi kwesixhobo se-laser iyakwazi ukukhawulela i-angle ye-divergency ye-beam ukuya ngaphantsi kwe-0.5-0.6mrad.

9. Iinkxalabo zethu eziphambili zinxulumene nokunyuka nokuwa kwamaxesha, ukunika i-laser pulse emfutshane kakhulu. Iinkcukacha zibonisa imfuneko ye-2V/7A. Ngaba oku kuthetha ukuba unikezelo lwamandla kufuneka luhambise la maxabiso ngaphakathi kwe-3-6ns, okanye kukho impompo yentlawulo edibeneyo kwimodyuli?

I-3-6n ichaza ubude be-pulse ye-laser ye-output beam kunokuba ixesha lokunikezelwa kwamandla angaphandle. Ubonelelo lwamandla lwangaphandle lufuna nje ukuqinisekisa:

① Ungeniso lwesikweri somqondiso wamaza;

② Ubude bexesha lesiginali ye-square wave iku-milliseconds.

10. Ziziphi izinto ezichaphazela uzinzo lwamandla?

Uzinzo lwamandla lubhekiselele kubuchule belaser ukugcina amandla ombane aphumayo angaguquguqukiyo kwixesha elide lokusebenza. Izinto ezichaphazela uzinzo lwamandla ziquka:

① Ukutshintsha kobushushu

② Ukuguquguquka kumbane welaser

③ Ukwaluphala kunye nokungcoliseka kwamalungu okukhanya

④ Ukuzinza komthombo wempompo

11. Yintoni i-TIA?

I-TIA imele “i-Transimpedance Amplifier,” isikhulisa-lizwi esiguqula imiqondiso yangoku ibe ziimpawu zombane. I-TIA isetyenziselwa ubukhulu becala ukukhulisa imiqondiso yangoku ebuthathaka eveliswa ziifotodiode zokuqhubela phambili nohlalutyo. Kwiinkqubo ze-laser, iqhele ukusetyenziswa kunye ne-diode yempendulo ukuzinzisa amandla emveliso yelaser.

12. Isakhiwo kunye nomgaqo we-erbium glass laser

Njengoko kubonisiwe kulo mzobo ungezantsi
