MOPA (Master Oscillator Power Amplifier) Kufotokozera Kwamapangidwe
M'malo aukadaulo wa laser, mawonekedwe a Master Oscillator Power Amplifier (MOPA) amayimira ngati chowunikira chatsopano, chopangidwa kuti chipereke zotulutsa za laser zapamwamba komanso zamphamvu. Dongosolo lodabwitsali lili ndi zigawo ziwiri zofunika kwambiri: Master Oscillator ndi Power Amplifier, chilichonse chimagwira ntchito yapadera komanso yofunika kwambiri.
Master Oscillator:
Pakatikati pa dongosolo la MOPA pali Master Oscillator, gawo lomwe limapanga laser yokhala ndi kutalika kwake, kulumikizana, komanso mtengo wapamwamba wa mtengo. Ngakhale kutulutsa kwa Master Oscillator nthawi zambiri kumakhala kocheperako, kukhazikika kwake ndi kulondola kwake kumapanga maziko a magwiridwe antchito onse.
Mphamvu ya Amplifier:
Ntchito yayikulu ya Power Amplifier ndikukulitsa laser yopangidwa ndi Master Oscillator. Kupyolera mu njira zingapo zokulirakulira, zimakulitsa kwambiri mphamvu yonse ya laser pomwe ikuyesetsa kusunga kukhulupirika kwa mawonekedwe a mtengo woyambirira, monga kutalika kwa mafunde ndi kulumikizana.
Dongosololi limapangidwa ndi magawo awiri: kumanzere, pali gwero la laser lambewu lomwe lili ndi mtengo wapamwamba kwambiri, ndipo kumanja, pali gawo loyamba kapena lamitundu yambiri yama fiber fiber amplifier. Zigawo ziwirizi palimodzi zimapanga master oscillator power amplifier (MOPA) optical source.
Multistage Amplification mu MOPA
Kuti mukwezenso mphamvu ya laser ndikukulitsa mtundu wa mtengo, machitidwe a MOPA atha kuphatikizira magawo angapo okulitsa. Gawo lililonse limagwira ntchito zokulirapo, limodzi kukwaniritsa kusamutsa mphamvu moyenera komanso kukhathamiritsa kwa laser.
Pre-amplifier:
Mu multistage amplifier system, Pre-amplifier imagwira ntchito yofunika kwambiri. Imapereka kukulitsa koyambirira pakutulutsa kwa Master Oscillator, kukonzekera laser kuti ikwaniritse magawo okulirapo, apamwamba kwambiri.
Amplifier Yapakatikati:
Gawoli limawonjezeranso mphamvu ya laser. M'makina ovuta a MOPA, pakhoza kukhala magawo angapo a Amplifiers apakatikati, iliyonse imakulitsa mphamvu ndikuwonetsetsa mtundu wa mtengo wa laser.
Amplifier Yomaliza:
Monga gawo lomaliza la kukulitsa, Final Amplifier imakweza mphamvu ya laser pamlingo womwe mukufuna. Chisamaliro chapadera chimafunika panthawiyi kuti chiwongolero cha mtengowo chitetezeke ndikupewa kutuluka kwa zotsatira zopanda malire.
Ntchito ndi Ubwino wa MOPA Structure
Kapangidwe ka MOPA, ndi kuthekera kwake kopereka zotulutsa zamphamvu kwambiri kwinaku akusunga mawonekedwe a laser monga kulondola kwa mafunde, mtundu wa mtengo, ndi mawonekedwe a pulse, amapeza ntchito m'magawo osiyanasiyana. Izi zikuphatikiza kukonza zinthu moyenera, kafukufuku wasayansi, umisiri wamankhwala, ndi kulumikizana ndi fiber optic, kungotchulapo zochepa. Kugwiritsa ntchito ukadaulo wokulitsa masitepe ambiri kumalola makina a MOPA kuti apereke ma laser amphamvu kwambiri osinthika modabwitsa komanso magwiridwe antchito apamwamba.

Mu LSP pulse fiber laser series, the1064nm nanosecond kugunda CHIKWANGWANI laserimagwiritsa ntchito mawonekedwe okhathamiritsa a MOPA (Master Oscillator Power Amplifier) okhala ndi ukadaulo wamasitepe angapo komanso kapangidwe kake. Imakhala ndi phokoso lochepa, mtengo wabwino kwambiri, mphamvu yapamwamba kwambiri, kusintha kosinthika kwa parameter, komanso kuphatikiza kosavuta. Chogulitsacho chimagwiritsa ntchito ukadaulo wowongolera mphamvu zamagetsi, kupondereza kuwonongeka kwamphamvu mwachangu m'malo otentha kwambiri komanso otsika, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchitoTOF (Nthawi Yonyamuka)magawo kuzindikira.
