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 nekusimudzira munda rakatyora 10,000 watts kekutanga, chimiro chefiber laser chinonyanya kushandisa optical bidirectional kupomba, kugadzira resonator, nekuferefetwa kwekutsetseka kwefiber. Laser yakasvika 58.3%.
Zvisinei, kunyange zvazvo kushandiswa kwefiber pombi chiedza uye laser coupling tekinoroji yekugadzira fiber lasers inogona zvinobudirira kuvandudza simba rekubuda refiber lasers, asi panguva imwechete kune kuomarara, izvo zvisingaenderane kune optical lens kuvaka nzira yekuona, kamwe chete laser inoda kufambiswa mukugadzira nzira yekuona, ipapo nzira yemaziso inodawo kugadziridzwa, iyo inodzikamisa kushandiswa kwakakura kwepombi yepombi chimiro fiber lasers.

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 gireti inosarudza wavelength mukuita kwekutenderera, yobva yaburitsa iyo yakasarudzwa wavelength, nepo MOPA inoshandisa wavelength yakasarudzwa negure sechiedza chembeu, uye chiedza chembeu chinowedzerwa pasi pechiito chekutanga. -level amplifier, saka simba rekubuda refiber laser rinozovandudzwa kune imwe nhanho. Kwenguva refu yenguva, fiber lasers ine MPOA chimiro yakashandiswa seyakasarudzika chimiro chepamusoro-simba fiber lasers. Zvisinei, zvidzidzo zvakazotevera zvakaona kuti simba guru rinobuda muchimiro ichi riri nyore kutungamira mukusagadzikana kwekupararira kwepakati mukati me fiber laser, uye kubuda kwe laser kupenya kuchakanganiswa kune imwe nhanho, iyo inewo maitiro akananga. pane-high-power output effect.

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, pachine makore. mabhodhoro mazhinji mune tekinoroji iripo. 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 yekusagadzikana kweiyo transverse modhi kupisa kwefiber, uye kusviba kwephoton kunonyanya kureva kuti kana fiber laser ichiramba ichiburitsa mazana ewatts kana akati wandei kilowatts emagetsi, simba rekubuda rinoratidza kukurumidza kuderera maitiro, uye kune imwe dhigirii yekudzikira pane inoenderera yakakwira simba kubuda 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.
