Kusintha kwaukadaulo kwa ma lasers amphamvu kwambiri

Kukhathamiritsa kwalaser fiberkapangidwe

1, mawonekedwe a mpope wopepuka

Oyambirira CHIKWANGWANI lasers makamaka ntchito kuwala mpope linanena bungwe,laserlinanena bungwe, mphamvu yake linanena bungwe ndi otsika, kuti mwamsanga kusintha linanena bungwe mphamvu ya CHIKWANGWANI lasers mu nthawi yochepa pali vuto lalikulu. Mu 1999, mphamvu linanena bungwe CHIKWANGWANI laser kafukufuku ndi kumunda chitukuko anathyola 10,000 Watts kwa nthawi yoyamba, dongosolo CHIKWANGWANI laser makamaka ntchito kuwala bidirectional kupopera, kupanga resonator, ndi kafukufuku wa otsetsereka dzuwa la CHIKWANGWANI laser anafika 58,3%.
Komabe, ngakhale ntchito CHIKWANGWANI mpope kuwala ndi luso laser lumikiza kukhala CHIKWANGWANI lasers akhoza bwino patsogolo linanena bungwe mphamvu ya CHIKWANGWANI lasers, koma pa nthawi yomweyo pali zovuta, amene si abwino kwa mandala kuwala kumanga njira kuwala, kamodzi laser ayenera kusunthidwa m'kati kumanga njira kuwala, ndiye kuwala njira komanso ayenera kusinthidwa kachipangizo CHIKWANGWANI laser kamangidwe kake.

2, kapangidwe ka oscillator mwachindunji ndi mawonekedwe a MOPA

Ndi chitukuko cha ma lasers a CHIKWANGWANI, zotchingira mphamvu zotchingira zidasintha pang'onopang'ono zida zamagalasi, kufewetsa masitepe opangira ma fiber lasers ndikuwongolera mosadukiza magwiridwe antchito a fiber lasers. Kachitidwe kachitukuko kameneka kakuyimira kuchitapo kanthu kwapang'onopang'ono kwa fiber lasers. Kapangidwe ka Direct oscillator ndi mawonekedwe a MOPA ndizinthu ziwiri zodziwika bwino zama fiber lasers pamsika. Kapangidwe ka oscillator mwachindunji ndikuti grating imasankha kutalika kwa mafunde mumayendedwe a oscillation, kenako imatulutsa mawonekedwe osankhidwa, pomwe MOPA imagwiritsa ntchito kutalika kwa mawonekedwe osankhidwa ndi kabati ngati kuwala kwa mbewu, ndipo kuwala kwa mbewu kumakulitsidwa pansi pakuchita kwa amplifier yamlingo woyamba, kotero mphamvu yotulutsa ya fiber laser idzakhalanso bwino. Kwa nthawi yayitali, ma laser a fiber okhala ndi mawonekedwe a MPOA akhala akugwiritsidwa ntchito ngati mawonekedwe okondedwa a ma laser amphamvu kwambiri. Komabe, kafukufuku wotsatira apeza kuti kutulutsa mphamvu kwapamwamba mu dongosololi n'kosavuta kutsogolera kusakhazikika kwa kugawa kwa malo mkati mwa fiber laser, ndipo kuwala kwa laser kumatulutsa kudzakhudzidwa pamlingo wina, womwe umakhudzanso mwachindunji kutulutsa mphamvu.

Ndi chitukuko cha luso kupopera

Kutalika kwa kupopera koyambirira kwa ytterbium-doped fiber laser nthawi zambiri kumakhala 915nm kapena 975nm, koma mafunde awiri opopa awa ndi nsonga zamayamwidwe a ytterbium ion, chifukwa chake amatchedwa kupopa molunjika, kupopera mwachindunji sikunagwiritsidwe ntchito kwambiri chifukwa cha kutayika kwachulukidwe. Ukadaulo wa kupopera kwa in-band ndikuwonjeza kwaukadaulo wopopa mwachindunji, momwe kutalika kwa mafunde pakati pa kupopera kwamphamvu ndi kutalika kwapang'onopang'ono kumakhala kofanana, ndipo kutayika kwa kuchuluka kwa kupopera kwapakati ndi kochepa kuposa kupopera mwachindunji.

High mphamvu CHIKWANGWANI laserchitukuko chaukadaulo botolo

Ngakhale CHIKWANGWANI lasers ndi mkulu ntchito m'mafakitale asilikali, zachipatala ndi zina, China kulimbikitsa ntchito lonse la CHIKWANGWANI lasers mwa pafupifupi 30 zaka kafukufuku luso ndi chitukuko, koma ngati mukufuna kupanga CHIKWANGWANI lasers akhoza linanena bungwe mphamvu apamwamba, pali akadali botolo ambiri mu luso alipo. Mwachitsanzo, ngati mphamvu linanena bungwe CHIKWANGWANI laser akhoza kufika limodzi CHIKWANGWANI single-mode 36.6KW; Chikoka cha kupopera mphamvu pa CHIKWANGWANI laser linanena bungwe mphamvu; Chikoka cha ma lens matenthedwe amakhudza mphamvu ya fiber laser.

Kuphatikiza apo, kafukufuku waukadaulo wapamwamba wotulutsa mphamvu ya fiber laser ayeneranso kuganizira za kukhazikika kwa mawonekedwe opingasa komanso mdima wa Photon. Kupyolera mu kufufuza, zikuwonekeratu kuti chikoka cha kusakhazikika kwa njira yodutsa ndi kutentha kwa fiber, ndipo kuwala kwa photon kumatanthawuza kuti pamene fiber laser imatulutsa ma Watts mazana ambiri kapena ma kilowati angapo amphamvu, mphamvu yotulutsa idzawonetsa kuchepa kwachangu, ndipo pali malire pa kutulutsa mphamvu kwamphamvu kwa fiber laser.

Ngakhale kuti zomwe zimayambitsa mdima wa photon sizinafotokozedwe bwino pakali pano, anthu ambiri amakhulupirira kuti mpweya woipa wa oxygen ndi kuyamwa kwapadera kungapangitse kuti pakhale mdima wa photon. Pazifukwa ziwirizi, njira zotsatirazi zikuperekedwa kuti ziletse zotsatira za mdima wa photon. Monga zotayidwa, phosphorous, ndi zina zotero, pofuna kupewa kutengerapo mayamwidwe kutengerapo, ndiyeno wokometsedwa CHIKWANGWANI yogwira kuyesedwa ndi ntchito, muyezo yeniyeni ndi kusunga 3KW mphamvu linanena bungwe kwa maola angapo ndi kusunga 1KW mphamvu khola linanena bungwe kwa maola 100.
