Tekinoroji shanduko yeakakwira simba fiber lasers

Optimization offiber laserchimiro

1, nzvimbo yechiedza pombi chimiro

Early fiber lasers ainyanya kushandiswa optical pombi kubuda,laserkubuda, simba rayo rekubuda rakaderera, kuitira kukurumidza kuvandudza simba rekubuda kwefiber lasers munguva pfupi pane kuoma kukuru. Muna 1999, simba rekubuda refiber laser research and development field rakatyora 10,000 watts kekutanga, magadzirirwo efiber laser anonyanya kushandisa optical bidirectional pumping, kugadzira resonator, nekuferefetwa kwekutenuka kwefiber laser kwakasvika 58.3%.
Nekudaro, kunyangwe kushandiswa kwefiber pombi mwenje uye laser coupling tekinoroji yekugadzira fiber lasers inogona kunyatso kuvandudza simba rekubuda refiber lasers, asi panguva imwe chete pane kuoma, izvo zvisingaenderane neiyo optical lens kuvaka iyo nzira yekuona, kana laser ichida kufambiswa mukugadzira nzira yekuona, ipapo nzira yemaziso inodawo kudzokororwa yefiber optical pombi.

2, yakananga oscillator chimiro uye MOPA chimiro

Nekuvandudzwa kwefiber lasers, cladding power strippers zvishoma nezvishoma zvakatsiva zvikamu zvelens, kurerutsa matanho ekusimudzira efiber lasers uye zvisina kunanga kuvandudza kushanda kwefiber lasers. Iyi yekusimudzira maitiro inomiririra kuita zvishoma nezvishoma kwefiber lasers. Yakananga oscillator chimiro uye MOPA chimiro ndiwo maviri akajairika zvimiro zvefiber lasers pamusika. Iyo yakananga oscillator chimiro ndechekuti iyo grating inosarudza wavelength mukuita oscillation, yobva yaburitsa iyo yakasarudzwa wavelength, nepo MOPA inoshandisa wavelength yakasarudzwa negure sechiedza chembeu, uye mwenje wembeu unokwidziridzwa pasi pechiito cheyekutanga-level amplifier, saka simba rekubuda refiber laser richavandudzwa kune imwe nhanho. Kwenguva refu yenguva, fiber lasers ine MPOA chimiro yakashandiswa seyakasarudzika chimiro chepamusoro-simba fiber lasers. Zvisinei, zvidzidzo zvinotevera zvakawana kuti simba guru-simba rinobuda muchimiro ichi riri nyore kutungamira mukusagadzikana kwekugoverwa kwepakati mukati mefiber laser, uye kubuda kwelaser kupenya kuchakanganiswa kune imwe nhanho, iyo inewo mhedzisiro yakananga pane yakakwirira-simba rinobuda mhedzisiro.

Nekuvandudzwa kwekupomba tekinoroji

Iyo yekupomba wavelength yekutanga ytterbium-doped fiber laser inowanzoita 915nm kana 975nm, asi maviri aya ekupomba wavelengths ndiwo epamusoro ekunyudza eytterbium ions, saka inodaidzwa kunzi kupomba kwakananga, kupomba kwakananga hakuna kushandiswa zvakanyanya nekuda kwekurasikirwa kwehuwandu. In-band pumping tekinoroji ndeyekuwedzera kweiyo yakananga kupomba tekinoroji, umo iyo wavelength pakati peiyo wavelength yekupomba uye transmitting wavelength yakafanana, uye quantum kurasikirwa mwero we-in-band kupomba idiki pane iyo yekupomba yakananga.

High simba fiber lasertekinoroji yekuvandudza tekinoroji

Kunyangwe mafiber lasers ane yakakwirira application kukosha mumauto, ekurapa uye mamwe maindasitiri, China yakakurudzira kushandiswa kwakakura kwefiber lasers kuburikidza neanoda kusvika makore makumi matatu ekutsvaga tekinoroji nekusimudzira, asi kana iwe uchida kugadzira fiber lasers inogona kuburitsa simba repamusoro, kuchine akawanda mabhodhoro mune iripo tekinoroji. Semuenzaniso, kana simba rekubuda refiber laser rinogona kusvika kune imwe-fiber single-mode 36.6KW; Kupesvedzera kwesimba rekupomba pane fiber laser inobuda simba; Iyo pesvedzero yemafuta lens mhedzisiro pane inobuda simba refiber laser.

Pamusoro pezvo, tsvakiridzo yesimba repamusoro rekuburitsa tekinoroji yefiber laser inofanirawo kufunga kugadzikana kweiyo transverse mode uye photon kusviba maitiro. Kuburikidza nekuferefeta, zviri pachena kuti pesvedzero yeiyo transverse mode kusagadzikana ndeye fibre yekudziya, uye iyo photon kusviba mhedzisiro inonyanya kureva kuti kana iyo fiber laser ikaramba ichiburitsa mazana ewatts kana akati wandei kilowatts emagetsi, simba rekubuda rinoratidza kukurumidza kuderera maitiro, uye pane imwe nhanho yekudzikira pane inoenderera yakakwira simba rekubuda kwefiber laser.

Kunyangwe izvo zvinokonzeresa kusviba kwephoton hazvisati zvanyatsotsanangurwa parizvino, vanhu vazhinji vanotenda kuti oxygen defect centre uye kubhadharisa kutamisa kutorwa kunogona kutungamira mukuitika kwephoton kusviba. Pazvinhu zviviri izvi, nzira dzinotevera dzinonzi inhibit photon darkening effect. Zvakadai sealuminium, phosphorus, nezvimwewo, kuitira kuti udzivise kubhadharisa kutamiswa, uyezve iyo yakagadziridzwa inoshanda fiber inoedzwa uye inoshandiswa, chaiyo chiyero ndeyekuchengetedza 3KW simba rekubuda kwemaawa akati wandei uye kuchengetedza 1KW simba rakagadzikana kubuda kwemaawa zana.
