Reera pupuhi kaha-teiteime te hanganga MOPA muka-katoa
Ko ngā momo hanganga matua o ngā taiaho muka ko te hanganga kotahi-whakaoho, te huinga hihi me te hanganga whakakaha mana oscillating matua (MOPA). I roto i ēnei, kua noho te hanganga MOPA hei tētahi o ngā wāhi rangahau o nāianei nā tōna kaha ki te whakatutuki i te mahi-teitei.reera pāorooroputanga me te whānui o te pā me te auau tāruarua ka taea te whakarite (e kiia ana ko te whānui o te pā me te auau tāruarua).
Ko te kaupapa mahi o te taiaho MOPA penei: Ko te oscillator matua (MO) he pūtake purapura mahi-teiteirēhia haurua-irae whakaputa ana i te rama tohu purapura me ngā tawhā whakarerekētanga mā te whakarerekētanga pāoro tika. Ka whakaputa te mana whakahaere matua o te Field Programmable Gate Array (FPGA) i ngā tohu iahiko pāoro me ngā tawhā whakarerekētanga, e whakahaerehia ana e te ara iahiko taraiwa hei whakahaere i te pūtake purapura me te whakaoti i te whakarerekētanga tuatahi o te rama purapura. Whai muri i te whiwhinga o ngā tohutohu whakahaere mai i te papa whakahaere matua FPGA, ka tīmata te ara iahiko taraiwa pūtake papu i te pūtake papu hei whakaputa rama papu. Whai muri i te hononga o te rama purapura me te rama papu e te wehewehe hihi, ka werohia ki roto i te muka whatu takirua-whakakikoruatia Yb3+ (YDDCF) i roto i te kōwae whakanui whatu e rua-wāhanga. I roto i tēnei tukanga, ka mimitihia e ngā katote Yb3+ te kaha o te rama papu hei hanga i te tohatoha hurihanga taupori. Muri iho, i runga i ngā mātāpono o te whakanui ngaru haere me te tukunga whakaoho, ka tutuki i te rama tohu purapura te whakanui mana teitei i roto i te kōwae whakanui whatu e rua-wāhanga, ā, i te mutunga ka puta he mana teitei.te taiaho pāorooro nanohekonaNā te pikinga ake o te mana tihi, ka pāngia pea te tohu pāorooro kua whakanuia e te pēhanga whānui pāorooro nā te pānga kume i te whakanui. I roto i ngā mahi whaihua, he maha ngā wā ka whakamahia ngā hanganga whakanui maha-wāhanga hei whakarei ake i te mana putanga me te whai hua o te whakanui.
Ko te pūnaha ara iahiko taiaho MOPA he mea tito mai i te papa whakahaere matua FPGA, he pūtake papu, he pūtake purapura, he papa ara iahiko taraiwa, he whakakaha, me ētahi atu. Ka peia e te papa whakahaere matua FPGA te pūtake purapura ki te whakaputa i ngā pāoro marama purapura mata taumata-MW me ngā tawhā whakarerekē mā te whakaputa i ngā tohu hiko pāoro me ngā āhua ngaru whakarerekē, te whānui pāoro (5 ki te 200ns), me ngā tere tāruarua (30 ki te 900kHz). Ka whakaurua tēnei tohu mā te wehewehe ki te kōwae whakakaha whatu-wāhanga e rua e tito ana i te whakakaha mua me te whakakaha matua, ā, i te mutunga ka whakaputa i te taiaho pāoro poto-pūngao teitei mā te wehewehe whatu me te mahi whakakotahi. Kei te pūtake purapura he taputapu whakaahua ā-roto hei aroturuki i te mana putanga i te wā tūturu me te whakahoki atu ki te papa whakahaere matua FPGA. Ka whakahaerehia e te papa whakahaere matua ngā ara iahiko taraiwa papu 1 me te 2 hei whakatutuki i ngā mahi whakatuwhera me te kati o ngā pūtake papu 1, 2 me te 3. Ina tepūoko whakaahuaKi te kore e kitea te putanga rama tohu, ka whakawetohia e te papa whakahaere matua te pūtake papu hei ārai i te kino o te YDDCF me ngā taputapu whatu nā te korenga o te whakaurunga rama purapura.
Ko te pūnaha ara whatu taiaho MOPA he hanganga muka-katoa, ā, he kōwae wiri matua me te kōwae whakanui rua-wāhanga. Ko te kōwae wiri matua he taiaho haurua-ira (LD) me te roangaru waenga o te 1064nm, te whānui raina o te 3nm, me te mana putanga tonu mōrahi o te 400mW hei pūtake purapura, ā, ka honoa ki te kupenga muka Bragg (FBG) me te whakaata o te 99%@1063.94nm me te whānui raina o te 3.5nm hei hanga i tētahi pūnaha whiriwhiri roangaru. Ko te kōwae whakanui rua-wāhanga he hoahoa papu whakamuri, ā, ko te YDDCF me ngā diameter matua o te 8 me te 30μm kua whirihorahia hei pāpāho whakanui. Ko ngā tauwehenga mimiti papu paninga e rite ana ko te 1.0 me te 2.1dB/m@915nm, ia.
