Mimwe Mibvunzo Inobatsira Nezve Erbium Girazi Laser

1. Ndeupi musiyano uripo pakati pehupamhi hwepuruzi (ns) nehupamhi hwepuruzi (ms)?

Musiyano uripo pakati pe pulse width (ns) uye pulse width (ms) ndeyotevera: ns inoreva nguva yekuputika kwechiedza, ms inoreva nguva yekuputika kwemagetsi panguva yemagetsi.

2. Ko mutyairi welaser anofanirwa kupa pfuti pfupi inokonzeresa 3-6ns, kana iyo module inogona kuibata yega?

Hapana yekunze modulation module inodiwa; chero paine kupuruzira mu ms renji, module inogona kugadzira ns light pulse pachayo.

3. Zvinokwanisika here kuwedzera tembiricha yekushanda kusvika ku85 ° C?

Kupisa kwekushisa hakugoni kusvika 85 ° C; tembiricha yepamusoro yatakaedza i -40°C kusvika 70°C.

4. Pane mhango kuseri kwelenzi yakazadzwa nenitrogen kana zvimwe zvinhu kuti ive nechokwadi chekuti mhute haiumbe mukati mukupisa kwakanyanya?

Iyo sisitimu yakagadzirirwa kushandiswa pakudziya kwakadzika se -40 ° C uye pamusoro, uye danda-rinowedzera lens, iro rinoshanda sehwindo remaziso, harizoputi. Iyo mhango yakavharwa, uye zvigadzirwa zvedu zvakazadzwa nenitrogen kuseri kwelenzi, kuve nechokwadi chekuti lenzi iri mukati meinert gasi nharaunda, ichichengeta laser mumhepo yakachena.

5. Chii chinonzi lasing medium?

Takashandisa Er-Yb girazi sechinhu chinoshanda.

6. Iyo lasing medium inopomba sei?

Iyo compact chirp pane submount yakarongedzwa diode laser yakashandiswa kureba kupomba iyo inoshanda svikiro.

7. Laser cavity inoumbwa sei?

Iyo laser cavity yakaumbwa neyakavharwa Er-Yb girazi uye inobuda coupler.

8. Iwe unowana sei 0.5 mrad kusiyana? Unogona kuita zvidiki here?

Iyo yakabatanidzwa danda-yekuwedzera uye collimation system mukati meiyo laser mudziyo inokwanisa kumanikidza divergency angle yedanda kusvika yakaderera se0.5-0.6mrad.

9. Zvinetso zvedu zvekutanga zvine chekuita nekusimuka nekudonha nguva, ipa iyo pfupi yakanyanyisa laser pulse. Iyo yakatarwa inoratidza chinodiwa che2V/7A. Izvi zvinoreva here kuti magetsi anofanirwa kuendesa aya maitiro mukati me3-6ns, kana pane pombi yekuchaja yakabatanidzwa mune module?

Iyo 3-6n inotsanangura iyo pulse nguva yelaser inobuda danda kwete nguva yekunze kwesimba rekupa. Iyo yekunze magetsi inopihwa inongoda chete gurantee:

① Kupinza kweskweya wave chiratidzo;

② Nguva yechiratidzo chesquare wave iri mumamilliseconds.

10. Ndezvipi zvinhu zvinokanganisa kugadzikana kwesimba?

Kugadzikana kwesimba kunoreva kugona kwelaser kuchengetedza inowirirana inobuda danda simba pamusoro penguva refu yekushanda. Zvinhu zvinokanganisa kugadzikana kwesimba zvinosanganisira:

① Kusiyana kwetembiricha

② Kuchinja-chinja kweiyo laser magetsi

③ Kuchembera uye kusvibiswa kwezvinhu zvemaziso

④ Kugadzikana kwepombi sosi

11. Chii chinonzi TIA?

TIA inomirira "Transimpedance Amplifier," inova amplifier inoshandura masaini azvino kuita masaini emagetsi. TIA inonyanya kushandiswa kukwidziridza isina simba masaini masaini anogadzirwa nemafotodiode kuti aenderere mberi kugadzirisa uye kuongorora. Mune laser masisitimu, inowanzo shandiswa pamwe chete nemhinduro diode kudzikamisa iyo laser kubuda simba.

12. Chimiro uye musimboti weerbium girazi laser
