Kufotokozera Kapangidwe ka MOPA (Master Oscillator Power Amplifier)
Mu gawo la ukadaulo wa laser, kapangidwe ka Master Oscillator Power Amplifier (MOPA) kamayimira ngati chizindikiro cha luso latsopano, lopangidwa kuti lipereke zotsatira za laser zapamwamba komanso zamphamvu. Dongosolo lovuta ili limapangidwa ndi zigawo ziwiri zofunika kwambiri: Master Oscillator ndi Power Amplifier, chilichonse chikuchita gawo lapadera komanso lofunikira.
Master Oscillator:
Pakati pa dongosolo la MOPA pali Master Oscillator, gawo lomwe limagwira ntchito popanga laser yokhala ndi kutalika kwa nthawi, mgwirizano, komanso khalidwe lapamwamba la kuwala. Ngakhale kuti mphamvu ya Master Oscillator nthawi zambiri imakhala yochepa, kukhazikika kwake ndi kulondola kwake ndizomwe zimapangitsa kuti dongosolo lonse ligwire ntchito.
Chowonjezera Mphamvu:
Ntchito yaikulu ya Power Amplifier ndikukulitsa laser yopangidwa ndi Master Oscillator. Kudzera mu njira zingapo zokulitsa, imakulitsa kwambiri mphamvu yonse ya laser pamene ikuyesetsa kusunga umphumphu wa mawonekedwe a kuwala koyambirira, monga kutalika kwa mafunde ndi mgwirizano.
Dongosololi makamaka lili ndi magawo awiri: kumanzere, pali gwero la laser la mbewu lomwe limatulutsa kuwala kwapamwamba kwambiri, ndipo kumanja, pali kapangidwe ka amplifier ya fiber optical fiber ya gawo loyamba kapena la magawo ambiri. Zigawo ziwirizi pamodzi zimapanga gwero la optical power amplifier (MOPA).
Kukula kwa Magawo Ambiri mu MOPA
Kuti apititse patsogolo mphamvu ya laser ndikukweza ubwino wa kuwala, makina a MOPA amatha kukhala ndi magawo angapo okulitsa. Gawo lililonse limagwira ntchito zosiyanasiyana zokulitsa, pamodzi kukwaniritsa kusamutsa mphamvu moyenera komanso magwiridwe antchito abwino a laser.
Chowonjezera cha Pre-amplifier:
Mu dongosolo lokulitsa maginito ambiri, Pre-amplifier imagwira ntchito yofunika kwambiri. Imapereka kukulitsa koyamba kwa Master Oscillator, kukonzekera laser kuti igwiritsidwe ntchito pamaginito otsatira, apamwamba kwambiri.
Amplifier Yapakatikati:
Gawoli limawonjezera mphamvu ya laser. Mu machitidwe ovuta a MOPA, pakhoza kukhala ma milingo angapo a Intermediate Amplifiers, iliyonse ikuwonjezera mphamvu pamene ikutsimikizira ubwino wa kuwala kwa laser.
Chowonjezera Chomaliza:
Pamene gawo lomaliza la kukulitsa, Final Amplifier imakweza mphamvu ya laser kufika pamlingo womwe mukufuna. Pa gawoli pakufunika chisamaliro chapadera kuti muwongolere ubwino wa kuwala ndikupewa kubuka kwa zotsatira zosalunjika.
Kugwiritsa Ntchito ndi Ubwino wa Kapangidwe ka MOPA
Kapangidwe ka MOPA, komwe kali ndi mphamvu yopereka mphamvu zambiri pamene kakusunga mawonekedwe a laser monga kulondola kwa kutalika kwa wavelength, khalidwe la beam, ndi mawonekedwe a pulse, kamagwiritsa ntchito m'magawo osiyanasiyana. Izi zikuphatikizapo kukonza zinthu molondola, kafukufuku wasayansi, ukadaulo wazachipatala, ndi kulumikizana kwa fiber optic, kungotchulapo zochepa. Kugwiritsa ntchito ukadaulo wokulitsa magawo ambiri kumalola makina a MOPA kupereka ma laser amphamvu kwambiri ndi kusinthasintha kodabwitsa komanso magwiridwe antchito abwino kwambiri.
MOPALaser ya UlusiKuchokera ku Lumispot Tech
Mu mndandanda wa laser wa LSP pulse fiber,1064nm nanosecond pulse fiber laserimagwiritsa ntchito kapangidwe ka MOPA (Master Oscillator Power Amplifier) kokonzedwa bwino komwe kali ndi ukadaulo wokulitsa magawo ambiri komanso kapangidwe ka modular. Ili ndi phokoso lochepa, mtundu wabwino kwambiri wa beam, mphamvu yayikulu, kusintha kwa magawo osinthika, komanso kuphatikizika kosavuta. Chogulitsachi chimagwiritsa ntchito ukadaulo wokonzanso mphamvu, kuletsa kuwonongeka kwa mphamvu mwachangu m'malo otentha kwambiri komanso otsika, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito muTOF (Nthawi Yoyendera Ndege)minda yozindikira.
