Ko te MOPA (Master Oscillator Power Amplifier) he hoahoa taiaho e whakarei ake ana i te mahi putanga mā te wehe i te pūtake purapura (master oscillator) mai i te wāhanga whakanui mana. Ko te ariā matua ko te whakaputa i tētahi tohu pāoro purapura kounga teitei me te master oscillator (MO), kātahi ka whakanuia te kaha e te whakakaha mana (PA), ā, i te mutunga ka tukuna he pāoro taiaho mana-teitei, kounga-hihiko teitei, me te whakahaere-tawhā. He whānuitia te whakamahinga o tēnei hoahoa i roto i te tukatuka ahumahi, te rangahau pūtaiao, me ngā tono hauora.
1.Ngā Painga Matua o te Whakanuia o te MOPA
①Ngā Tawhā Ngāwari me te Whakahaere:
- Whānuitanga Pāpāho Ka taea te Whakarite Motuhake:
Ka taea te whakarite i te whānui o te pā o te pā purapura motuhake mai i te wāhanga whakakaha, mai i te 1 ns ki te 200 ns.
- Te Auautanga Whakahoki Whakarerekētanga:
E tautoko ana i te whānuitanga o ngā tere tāruarua o te pā, mai i te pā kotahi ki te pā auau-tiketike taumata-MHz, hei whakatutuki i ngā hiahia tukatuka kanorau (hei tauira, te tohu tere-tiketike me te whakairo hōhonu).
②Te Kounga Hiko Teitei:
Ka mau tonu ngā āhuatanga iti-haruru o te pūtake purapura i muri i te whakanui, ka puta he kounga hihi tata-ki-te-whakawhitiwhiti (M² < 1.3), he pai mō te miihini tika.
③Pūngao me te Pūmautanga o te Pānga Teitei:
Mā te whakanui maha-wāhanga, ka taea e te pūngao kotahi-pānga te eke ki te taumata millijoule me te iti o te piki me te heke o te pūngao (<1%), he mea tino pai mō ngā tono ahumahi tino tika.
④Te Āheinga Tukatuka Matao:
Mā te whānui poto o te pāorooro (hei tauira, i te awhe nanohekona), ka taea te whakaiti i ngā pānga wera ki ngā rauemi, ka taea ai te tukatuka pai i ngā rauemi pakarukaru pēnei i te karāhe me te uku.
2. Āmio Matua (MO):
Ka whakaputahia e te MO he iti te mana engari he tino tika te whakahaere i ngā pāoro purapura. Ko te pūtake purapura he taiaho haurua-ira (LD) he taiaho muka rānei, e whakaputa ana i ngā pāoro mā te whakarerekētanga tika, mā te whakarerekētanga o waho rānei.
3.Whakakaha Mana (PA):
Ka whakamahia e te PA ngā whakakaha muka (pēnei i te muka i whakakīia ki te ytterbium, YDF) hei whakakaha i ngā pāoro purapura i roto i ngā wāhanga maha, kia nui ake ai te whakanui i te kaha pāoro me te mana toharite. Me karo te hoahoa whakakaha i ngā pānga kore-raina pērā i te marara Brillouin whakaohooho (SBS) me te marara Raman whakaohooho (SRS), me te pupuri tonu i te kounga hihi teitei.
MOPA vs. Ngā Taiaho Muka Whakawhiti-Q Tuku Iho
| Āhuatanga | Hanganga MOPA | Ngā Taiaho Whakawhiti-Q Tuku Iho |
| Te Whakarerekētanga Whānui o te Pānga | Ka taea te whakarite motuhake (1–500 ns) | Kua pumau (e whakawhirinaki ana ki te pana-Q, ko te nuinga he 50–200 ns) |
| Te Auautanga o te Whakahokinga | Ka taea te whakarite whānui (1 kHz–2 MHz) | Awhe pumau, whāiti rānei |
| Ngāwari | Teitei (ngā tawhā ka taea te whakarite) | Iti |
| Ngā horopaki tono | Te miihini tika, te tohu auau-teitei, te tukatuka rauemi motuhake | Te tapahi whānui, te tohu |
