Mafunso Ena Ofunika Okhudza Erbium Glass Laser

1. Kodi pali kusiyana kotani pakati pa pulse width (ns) ndi pulse width (ms)?

Kusiyana pakati pa pulse width (ns) ndi pulse width (ms) ndi motere: ns amatanthauza nthawi ya kuphulika kwa kuwala, ms amatanthauza nthawi ya mphamvu yamagetsi panthawi yamagetsi.

2. Kodi dalaivala wa laser amayenera kupereka chiwongolero chachifupi cha 3-6ns, kapena gawoli lingathe kuligwira lokha?

Palibe gawo losinthira lakunja lomwe limafunikira; bola ngati pali kugunda mumtundu wa ms, gawoli likhoza kupanga ns kuwala kugunda paokha.

3. Kodi n'zotheka kuwonjezera kutentha kwa ntchito mpaka 85 ° C?

Kutentha sikungathe kufika 85 ° C; kutentha kwakukulu komwe tayesako ndi -40°C mpaka 70°C.

4. Kodi kuseri kwa disololo kuli kabowo kodzaza ndi nayitrogeni kapena zinthu zina kuti chifunga chisapangike mkati mozizira kwambiri?

Dongosololi limapangidwa kuti lizigwiritsidwa ntchito kutentha mpaka -40 ° C ndi kupitilira apo, ndipo lens yokulitsa mtengo, yomwe imakhala ngati zenera la kuwala, sidzaphulika. Mphepete mwatsekedwa, ndipo zogulitsa zathu zimadzazidwa ndi nayitrogeni kuseri kwa mandala, kuwonetsetsa kuti mandala ali mkati mwa mpweya wopanda mpweya, kusunga laser pamalo oyera.

5. Kodi sing'anga yotsekemera ndi chiyani?

Tidagwiritsa ntchito galasi la Er-Yb ngati sing'anga yogwira ntchito.

6. Kodi sing'anga yotsekemera imapopa bwanji?

Kulira kocheperako pa submount packed diode laser kunagwiritsidwa ntchito kutulutsa sing'anga yogwira kwa nthawi yayitali.

7. Kodi patsekeke laser imapangidwa bwanji?

Mphuno ya laser idapangidwa ndi galasi lokutidwa la Er-Yb ndi chopopera chotulutsa.

8. Kodi mumakwaniritsa bwanji 0,5 mrad divergency? Kodi mungathe kuchita zazing'ono?

Njira yophatikizira yokulirapo komanso yolumikizirana mkati mwa chipangizo cha laser imatha kuletsa mbali yosiyana ya mtengowo mpaka 0.5-0.6mrad.

9. Zodetsa nkhawa zathu zazikulu zimakhudzana ndi nthawi yokwera ndi kugwa, perekani kugunda kwa laser kwakufupi kwambiri. Mafotokozedwe akuwonetsa kufunikira kwa 2V / 7A. Kodi izi zikutanthauza kuti magetsi ayenera kupereka izi mkati mwa 3-6ns, kapena pali mpope wamagetsi wophatikizidwa mu module?

The 3-6n imalongosola kutalika kwa nthawi yotulutsa laser kusiyana ndi nthawi ya mphamvu yakunja. Mphamvu zamagetsi zakunja zimangofunika kutsimikizira:

① Kulowetsa chizindikiro cha mafunde a square;

② Kutalika kwa chizindikiro cha square wave ndi ma milliseconds.

10. Kodi ndi zinthu ziti zomwe zimakhudza kukhazikika kwa mphamvu?

Kukhazikika kwamphamvu kumatanthawuza kuthekera kwa laser kukhalabe ndi mphamvu zotulutsa zotulutsa nthawi yayitali. Zomwe zimakhudza kukhazikika kwamagetsi ndi izi:

① Kusintha kwa kutentha

② Kusinthasintha kwa magetsi a laser

③ Kukalamba ndi kuipitsidwa kwa zinthu zowoneka bwino

④ Kukhazikika kwa gwero la mpope

11. Kodi TIA ndi chiyani?

TIA imayimira "Transimpedance Amplifier," yomwe ndi amplifier yomwe imasintha ma siginecha apano kukhala ma siginecha amagetsi. TIA imagwiritsidwa ntchito makamaka kukulitsa ma siginecha ofooka omwe amapangidwa ndi ma photodiode kuti apitilize kukonza ndi kusanthula. M'machitidwe a laser, nthawi zambiri amagwiritsidwa ntchito limodzi ndi diode yoyankha kuti akhazikitse mphamvu yotulutsa laser.

12. Kapangidwe ndi mfundo ya erbium galasi laser
