Malunga MOPA

I-MOPA (I-Master Oscillator Power Amplifier) ​​luyilo lwelaser oluphucula ukusebenza kwemveliso ngokwahlula umthombo wembewu (i-oscillator enkulu) ukusuka kwinqanaba lokukhulisa amandla. Ingcamango engundoqo ibandakanya ukuvelisa i-high-quality seed pulse signal kunye ne-master oscillator (MO), ethi emva koko ikhulise amandla yi-amplifier yamandla (PA), ekugqibeleni ihambisa amandla aphezulu, i-high-beam-quality, kunye ne-parameter-controllable laser pulses. Olu lwakhiwo lusetyenziswa ngokubanzi kushishino, uphando lwezenzululwazi, kunye nezicelo zonyango.

1.Izinto ezilungileyo ezingundoqo zoKwandiswa kwe-MOPA

①Iiparamitha eziguquguqukayo nezinokulawulwa:

-Ububanzi bePulse obuhlengahlengiswa ngokuzimeleyo:

Ububanzi be-pulse yembewu ye-pulse bunokulungiswa ngokuzimeleyo kwinqanaba le-amplifier, ngokuqhelekileyo ukusuka kwi-1 ns ukuya kwi-200 ns.

-Ireyithi yokuPhinda eLungiselelayo:

Ixhasa uluhlu olubanzi lwamazinga okuphindaphinda kwe-pulse, ukusuka kwi-single-shot ukuya kwi-MHz-level high-frequency pulses, ukuhlangabezana neemfuno ezahlukeneyo zokucubungula (umzekelo, ukuphawula okukhawulezayo kunye nokukrola okunzulu).

②Umgangatho ophezulu weBeam:
Iimpawu zengxolo ephantsi yomthombo wembewu zigcinwa emva kokwandiswa, ukunikezela ngomgangatho we-beam okufutshane ne-diffraction-limited (M² <1.3), ilungele ukwenziwa ngomatshini ngokuchanekileyo.

③Amandla e-Pulse ephezulu kunye noZinzo:
Ngokukhuliswa kwamanqanaba amaninzi, amandla e-pulse enye anokufikelela kwinqanaba le-millijoule kunye nokuguquguquka okuncinci kwamandla (<1%), efanelekileyo kwizicelo ezichanekileyo zoshishino.

④Isakhono Sokucubungula okubandayo:
Ngobubanzi obufutshane be-pulse (umzekelo, kuluhlu lwe-nanosecond), iziphumo ze-thermal kwimathiriyeli zinokuncitshiswa, zivumela ukusetyenzwa kakuhle kwemathiriyeli enqabileyo njengeglasi kunye neeseramikhi.

2. I-Master Oscillator (MO):

I-MO ivelisa amandla aphantsi kodwa alawulwa ngokuchanekileyo iipulses zembewu. Umthombo wembewu ngokuqhelekileyo yi-laser semiconductor (LD) okanye i-fiber laser, evelisa i-pulses ngokumodareyitha ngokuthe ngqo okanye kwangaphandle.

3.Isikhulisa-Mandla (PA):

I-PA isebenzisa i-fiber amplifiers (ezifana ne-ytterbium-doped fiber, i-YDF) ukukhulisa i-pulses yembewu kwizigaba ezininzi, ukwandisa kakhulu amandla e-pulse kunye namandla aphakathi. Uyilo lweamplifier kufuneka luthintele iziphumo ezingezizo ezinje ngokusasazwa kweBrillouin (SBS) kunye nokuvuselela iRaman scattering (SRS), ngelixa igcina umgangatho ophezulu we-beam.
