Kushanduka kwehunyanzvi hwema lasers ane simba guru

Kugadzirisalaser yefaibhachimiro

1, chimiro chepombi yechiedza chemuchadenga

Mafiber laser ekutanga ainyanya kushandisa optical pump output,laserKuburitsa, simba rayo rekuburitsa rakaderera, kuitira kuti simba rekuburitsa remafiber laser riwedzere nekukurumidza munguva pfupi, pane kuoma kukuru. Muna 1999, simba rekuburitsa remunda wekutsvaga nekuvandudza fiber laser rakaputsa 10,000 watts kekutanga, chimiro chefiber laser chinonyanya kushandiswa kwe optical bidirectional pumping, ichigadzira resonator, nekuferefetwa kwekushanda kweslope yefiber laser kwakasvika 58.3%.
Zvisinei, kunyangwe kushandiswa kwetekinoroji yechiedza chepombi yefiber uye laser coupling kugadzira fiber lasers kunogona kuvandudza simba rekubuda kwefiber lasers, asi panguva imwe chete pane kuomarara, izvo zvisingakodzere kuti lenzi ye optical igadzire nzira ye optical, kana laser yada kutamiswa mukuvaka nzira ye optical, ipapo nzira ye optical inofanirawo kugadziriswazve, izvo zvinoganhurira kushandiswa kwakakura kwe optical pump structure fiber lasers.

2, chimiro che oscillator chakananga uye chimiro cheMOPA

Nekugadzirwa kwemafiber lasers, macladding power strippers akachinja zvishoma nezvishoma zvikamu zve lens, zvichiita kuti matanho ekugadzirwa kwemafiber lasers areruke uye nenzira isina kunanga kuvandudza mashandiro efiber lasers. Iyi nzira yekuvandudza inoratidza kushanda zvishoma nezvishoma kwemafiber lasers. Chimiro che direct oscillator uye chimiro cheMOPA ndizvo zviviri zvinowanzoitika zvemafiber lasers pamusika. Chimiro che direct oscillator ndechekuti grating inosarudza wavelength panguva ye oscillation, uye yozoburitsa wavelength yakasarudzwa, nepo MOPA ichishandisa wavelength yakasarudzwa ne grating sechiedza chembeu, uye chiedza chembeu chinowedzerwa pasi pekushanda kwe amplifier yedanho rekutanga, saka simba rekubuda kwefiber laser richavandudzwawo kusvika pamwero wakati. Kwenguva yakareba, mafiber lasers ane chimiro cheMPOA ave achishandiswa sechimiro chinofarirwa nemafiber lasers ane simba guru. Zvisinei, zvidzidzo zvakatevera zvakawana kuti simba guru rinobuda muchimiro ichi riri nyore kukonzera kusagadzikana kwekupararira kwenzvimbo mukati me fiber laser, uye kupenya kwe laser rinobuda kuchakanganiswa kusvika pamwero wakati, izvo zvinewo kukanganisa zvakananga pamhedzisiro yesimba guru rinobuda.

Nekuvandudzwa kwetekinoroji yekupomba

Kureba kwewavelength ye fiber laser yekutanga ye ytterbium-doped inowanzova 915nm kana 975nm, asi ma wavelength maviri aya ndiwo ma high peaks e ytterbium ions, saka inonzi direct pumping, direct pumping haina kushandiswa zvakanyanya nekuda kwekurasikirwa kwe quantum. Tekinoroji ye in-band pumping ikuwedzera kwetekinoroji ye direct pumping, umo wavelength iri pakati pe wavelength ye pumping ne transmitter wavelength yakafanana, uye quantum loss rate ye in-band pumping idiki pane ye direct pumping.

Laser ine simba gurudambudziko rekuvandudza tekinoroji

Kunyangwe fiber lasers dzichishandiswa zvakanyanya mumauto, zvokurapa nedzimwe nzvimbo, China yakasimudzira kushandiswa kwakakura kwefiber lasers kuburikidza nemakore angangoita makumi matatu ekutsvaga nekuvandudza tekinoroji, asi kana uchida kugadzira fiber lasers inogona kuburitsa simba rakawanda, kuchine zvipingamupinyi zvakawanda mu tekinoroji iripo. Semuenzaniso, kana simba rekuburitsa refiber laser rinogona kusvika kune single-fiber single-mode 36.6KW; Simba rekupomba simba rekuburitsa fiber laser; Simba rekupisa lenzi pasimba rekuburitsa fiber laser.

Pamusoro pezvo, tsvakiridzo ye tekinoroji yepamusoro yekuburitsa fiber laser inofanirawo kufunga nezvekugadzikana kwe transverse mode uye photon darkening effect. Kuburikidza nekuongorora, zviri pachena kuti chinhu chinokonzera kusagadzikana kwe transverse mode ndiko kupisa kwefiber, uye photon darkening effect inonyanya kureva kuti kana fiber laser ichiramba ichiburitsa mazana ewatts kana ma kilowatts akawanda esimba, simba rekuburitsa richaratidza kukurumidza kudzikira, uye pane mwero wakati wekudzikira pakubuda kwefiber laser nesimba rakawanda.

Kunyangwe zvikonzero chaizvo zvekusviba kwephoton zvisati zvanyatsotsanangurwa pari zvino, vanhu vazhinji vanotenda kuti oxygen defect centre uye charge transfer absorption zvinogona kutungamira mukusviba kwephoton. Pazvinhu izvi zviviri, nzira dzinotevera dzinokurudzirwa kudzivirira photon darkening effect. Zvakadai sealuminium, phosphorus, nezvimwewo, kuitira kudzivirira charge transfer absorption, uye ipapo optimized active fiber inoedzwa uye inoshandiswa, chiyero chaicho ndechekuchengetedza 3KW power output kwemaawa akati wandei uye kuchengetedza 1KW power stable output kwemaawa zana.
