Mibvunzo Inokosha Nezve Erbium Glass Laser

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

Musiyano uripo pakati pehupamhi hwepulse (ns) nehupamhi hwepulse (ms) ndewekuti: ns zvinoreva nguva yekupisa kwechiedza, ms zvinoreva nguva yekupisa kwemagetsi panguva yekupa simba.

2. Ko mutyairi welaser anofanira kupa pulse pfupi ye3-6ns, kana kuti module inogona kuibata yega here?

Hapana module yekunze inodiwa; chero bedzi paine pulse iri mu ms range, module inogona kugadzira ns light pulse yoga.

3. Zvinokwanisika here kuwedzera tembiricha yekushanda kusvika 85°C?

Tembiricha yekupisa haigone kusvika 85°C; tembiricha yepamusoro yatakaedza ndeye -40°C kusvika 70°C.

4. Pane here nzvimbo iri kuseri kwegirazi yakazadzwa nenitrogen kana zvimwe zvinhu zvinoita kuti mhute isaumbwe mukati kana tembiricha yakaderera?

Sisitimu iyi yakagadzirirwa kushandiswa patembiricha yakadzika kusvika -40°C zvichikwira, uye lenzi inokura mwenje, iyo inoshanda sehwindo rekuona, haizoputike nemhute. Mhute yacho yakavharwa, uye zvigadzirwa zvedu zvakazadzwa nenitrogen kuseri kwelenzi, zvichiita kuti lenzi ive munzvimbo ine gasi risingashande, zvichichengetedza laser munzvimbo yakachena.

5. Chii chinonzi lasing medium?

Takashandisa girazi reEr-Yb sechinhu chinoshanda.

6. Chinopombwa sei chinopombwa sei?

Chip chipfupi pa submount packed diode laser chaifanira kupomba active medium kwenguva refu.

7. Ko gomba relaser rinogadzirwa sei?

Mhara yelaser yakagadzirwa negirazi reEr-Yb rakaputirwa uye chinoburitsa chinobuda.

8. Ungawana sei musiyano we 0.5 mrad? Unogona kuita diki here?

Sisitimu yekuwedzera danda uye collimation iri mukati memudziyo welaser inokwanisa kuderedza kona yekusiyana kwedanda kusvika pa 0.5-0.6mrad.

9. Zvatinonyanya kufunga nezvazvo zvine chekuita nenguva yekukwira nekudonha, zvichipa kupfupika kwelaser pulse. Tsanangudzo yacho inoratidza chinodiwa che2V/7A. Izvi zvinoreva here kuti magetsi anofanira kupa izvi mukati me3-6ns, kana kuti pane charge pump yakabatanidzwa mumodule?

Iyo 3-6n inotsanangura nguva yekurova kwemoyo yemwaranzi inobuda nelaser pane nguva yesimba rekunze. Simba rekunze rinongoda kuvimbisa kuti:

① Kuiswa kwechiratidzo chewave chesikweya;

② Nguva yechiratidzo chewave chesikweya iri mumamilisekonzi.

10. Ndezvipi zvinhu zvinokanganisa kugadzikana kwesimba?

Kugadzikana kwesimba zvinoreva kugona kwelaser kuchengetedza simba remwenje rinobuda nguva dzose kwenguva refu yekushanda. Zvinhu zvinokanganisa kugadzikana kwesimba zvinosanganisira:

① Kuchinja kwetembiricha

② Kuchinja-chinja kwesimba remagetsi relaser

③ Kuchembera uye kusvibiswa kwezvinhu zvinoona

④ Kugadzikana kwepombi

11. Chii chinonzi TIA?

TIA inomirira "Transimpedance Amplifier," inova amplifier inoshandura masaini emagetsi kuita masaini emagetsi. TIA inonyanya kushandiswa kuwedzera masaini emagetsi asina simba anogadzirwa nemaphotodiode kuti awedzere kugadziriswa uye kuongororwa. Mumasisitimu elaser, inowanzo shandiswa pamwe chete ne feedback diode kudzikamisa simba rinobuda nelaser.

12. Maumbirwo uye musimboti we erbium glass laser

Sezvakaratidzwa mudhayagiramu iri pazasi
