MOPA (Master Oscillator Power Amplifier) Imiterere Ibisobanuro
Mu rwego rwa tekinoroji ya laser, imiterere ya Master Oscillator Power Amplifier (MOPA) ihagaze nkumucyo wo guhanga udushya, yagenewe gutanga umusaruro wa laser wujuje ubuziranenge nimbaraga. Sisitemu igoye igizwe nibice bibiri byingenzi: Master Oscillator na Power Amplifier, buri kimwe kigira uruhare rwihariye kandi rukomeye.
Umwigisha Oscillator:
Hagati ya sisitemu ya MOPA hari Master Oscillator, igice gishinzwe kubyara laser ifite uburebure bwihariye bwumuraba, guhuza, hamwe nubwiza buhebuje. Mugihe ibisohoka bya Master Oscillator mubusanzwe ari bike mububasha, ituze ryayo nibisobanuro bikora urufatiro rwimikorere ya sisitemu yose.
Imbaraga zongera imbaraga:
Igikorwa cyibanze cya Power Amplifier nukwongerera laser yakozwe na Master Oscillator. Binyuze mu ruhererekane rw'ibikorwa byo kongera imbaraga, byongera cyane imbaraga rusange za lazeri mugihe uharanira gukomeza ubusugire bwibiranga umwimerere wumwimerere, nkuburebure bwumuraba hamwe.
Sisitemu igizwe ahanini nibice bibiri: ibumoso, hari imbuto ya laser isoko yimbuto nziza-nziza, kandi iburyo, hari icyiciro cya mbere cyangwa ibyiciro byinshi bya optique fibre amplifier structure. Ibi bice byombi hamwe bigizwe na master oscillator power amplifier (MOPA) isoko ya optique.
Kwiyongera kwa Multistage muri MOPA
Kugirango urusheho kuzamura ingufu za laser no kunoza ubuziranenge bwibiti, sisitemu ya MOPA irashobora gushiramo ibyiciro byinshi byo kongera imbaraga. Buri cyiciro gikora imirimo itandukanye yo kongera imbaraga, hamwe hamwe kugera ku ihererekanyabubasha ryiza no gukora neza.
Imbere-yongerera imbaraga:
Muri sisitemu yo kongera imbaraga nyinshi, Pre-amplifier igira uruhare runini. Itanga amplification yambere kubisohoka bya Master Oscillator, itegura lazeri kubikurikira, urwego rwohejuru rwo kwongera.
Hagati ya Amplifier:
Iki cyiciro cyongera imbaraga za laser. Muri sisitemu igoye ya MOPA, hashobora kubaho urwego rwinshi rwa Intermediate Amplifiers, buri kimwe cyongera imbaraga mugihe cyemeza ubuziranenge bwibiti bya laser.
Amplifier Yanyuma:
Nkicyiciro cyo gusoza amplification, Final Amplifier izamura imbaraga za laser kurwego rwifuzwa. Birasabwa kwitabwaho cyane muriki cyiciro kugirango ugenzure ubuziranenge bwibiti kandi wirinde kugaragara kwingaruka zidafite umurongo.
Porogaramu ninyungu zuburyo bwa MOPA
Imiterere ya MOPA, hamwe nubushobozi bwayo bwo gutanga ingufu-nyinshi zisohoka mugihe gikomeza ibiranga laser nkuburebure bwumurambararo, ubwiza bwibiti, nuburyo bwa pulse, isanga porogaramu mubice bitandukanye. Ibi birimo gutunganya ibintu neza, ubushakashatsi bwa siyansi, ikoranabuhanga mu buvuzi, n’itumanaho rya fibre optique, kuvuga amazina make. Ikoreshwa rya tekinoroji ya amplistage tekinoroji ituma sisitemu ya MOPA itanga lazeri zifite ingufu nyinshi kandi zihindagurika kandi zikora neza.

Muri LSP pulse fibre laser ikurikirana ,.1064nm nanosekond pulse fibre laserikoresha imiterere ya MOPA (Master Oscillator Power Amplifier) hamwe na tekinoroji yo kwagura ibyiciro byinshi hamwe nubushakashatsi. Iranga urusaku ruto, ubwiza buhebuje, imbaraga zo hejuru cyane, guhuza ibipimo byoroshye, no koroshya kwishyira hamwe. Igicuruzwa gikoresha tekinoroji yindishyi zamashanyarazi, guhagarika neza kwangirika kwingufu zihuse mubushyuhe bwo hejuru nubushyuhe buke, bigatuma bikenerwa cyane mubisabwa muriTOF (Igihe-cy'Indege)imirima.
