Fiber lasers account yekuwedzera kugoverana kwemaindasitiri lasers gore negore nekuda kwechimiro chavo chakareruka, mutengo wakaderera, yakakwirira electro-optical shanduko inoshanda, uye yakanaka yekubuda mhedzisiro. Zvinoenderana nehuwandu, mafiber lasers akaverengera 52.7% yemusika weindasitiri laser muna 2020.
Zvichienderana nehunhu hwedanda rekubuda, fiber lasers inogona kukamurwa kuita mapoka maviri:inoenderera mberi laseruyepulse laser. Ndeupi mutsauko wehunyanzvi pakati pezviviri, uye ndeapi mamiriro ekushandisa akakodzera imwe neimwe? Izvi zvinotevera kuenzanisa kwakapfava kwemaapplication mumamiriro ezvinhu.
Sezvinoratidzwa nezita racho, iyo laser inobuda neinoenderera fiber laser inoenderera, uye simba rinochengetwa padanho rakatemwa. Iri simba ndiro rakayerwa simba re laser.Kubatsira kwekuenderera mberi fiber lasers ndeyekureba yakagadzikana kushanda.
Iyo laser yepulse laser "inopindirana". Ehe, iyi nguva yepakati inowanzove ipfupi kwazvo, inowanzoyerwa mumamilliseconds, mamicroseconds, kana kunyange nanoseconds uye picoseconds. Kuenzaniswa neinoenderera mberi laser, kusimba kwepulse laser kunogara kuchichinja, saka kune pfungwa dze "crest" uye "chidyiro".
Kuburikidza nepulse modulation, iyo pulsed laser inogona kuburitswa nekukurumidza uye inosvika pakakwirira simba panzvimbo yepamusoro, asi nekuda kwekuvapo kwechigero, avhareji simba rakaderera.Zvinogoneka kuti kana avhareji simba rakafanana, simba repamusoro repulse laser rinogona kuve rakakura kupfuura iro reinoenderera mberi laser, ichiwana yakakura simba density pane inoenderera laser, iyo inoratidzwa mukunyanya kupinza kugona mukati. kushandiswa kwesimbi. Panguva imwecheteyo, Inokodzerawo zvinhu zvinopisa zvinopisa zvisingagoni kumira zvakanyanya kupisa, pamwe chete nezvimwe zvinhu zvepamusoro-reflectivity.
Kuburikidza neakabuda simba maitiro ezviviri, tinogona kuongorora misiyano yekushandisa.
CW fiber lasers inowanzokodzera:
1. Kugadziriswa kwemidziyo mikuru, senge mota uye michina yengarava, kucheka nekugadzirisa mahwendefa makuru esimbi, uye dzimwe nguva dzekugadzirisa dzisinganzwisisi mhedzisiro yekupisa asi dzinonyanya kukoshesa mutengo.
2. Inoshandiswa mukuvhiya kucheka uye coagulation munharaunda yezvokurapa, zvakadai sehemostasis mushure mekuvhiyiwa, nezvimwewo.
3. Inoshandiswa zvakanyanya mu optical fiber kutaurirana masisitimu ekufambisa kwemasaini uye kukwidziridzwa, nekugadzikana kwepamusoro uye ruzha rwechikamu chakaderera.
4. Inoshandiswa mukushandisa senge spectral analysis, atomic physics kuyedza uye lidar mumunda wekutsvagisa kwesainzi, ichipa simba repamusoro uye yakakwirira beam quality laser kubuda.
Pulsed fiber lasers inowanzokodzera:
1. Kunyatso gadziridzwa kwezvinhu zvisingakwanise kumirisana nekupisa kwakasimba kana brittle zvinhu, sekugadzira machipisi emagetsi, girazi receramic, uye zvekurapa biological parts.
2. Izvo zvinhu zvine high reflectivity uye zvinogona nyore kukuvadza laser musoro pachayo nekuda kwekufungisisa. Semuenzaniso, kugadzirisa mhangura uye aluminium zvinhu
3. Kurapa kwepamusoro kana kucheneswa kwekunze kweiyo substrates inokuvadzwa nyore
4. Mamiriro ekugadzirisa anoda nguva pfupi simba repamusoro uye kupinza kwakadzika, sekucheka kweplate yakakora, kuchera zvinhu zvesimbi, nezvimwewo.
5. Mamiriro ezvinhu apo pulses inoda kushandiswa sezviratidzo zvechiratidzo. Zvakadai se optical fiber kutaurirana uye optical fiber sensors, nezvimwe.
6. Inoshandiswa mumunda webiomedical kuvhiyiwa kweziso, kurapwa kweganda uye kucheka matishu, nezvimwewo, nehupamhi hwepamusoro uye modulation performance.
7. Mukudhinda kwe 3D, zvikamu zvesimbi zvinogadzirwa nepamusoro-soro uye zvivako zvakaoma zvinogona kuwanikwa
8. Yepamusoro laser zvombo, nezvimwewo.
Pane mimwe misiyano pakati pepulsed fiber lasers uye inoenderera fiber lasers maererano nemisimboti, hunyanzvi hunhu uye mashandisiro, uye imwe neimwe inokodzera zviitiko zvakasiyana. Pulsed fiber lasers inokodzera maapplication anoda peak simba uye modulation kuita, senge kugadzira zvinhu uye bio-mushonga, nepo inoenderera fiber lasers yakakodzera zvikumbiro zvinoda kugadzikana kwepamusoro uye mhando yepamusoro yedanda, sekutaurirana uye tsvakiridzo yesainzi. Kusarudza iyo chaiyo fiber laser mhando zvichibva pane chaiyo zvinodiwa kuchabatsira kuvandudza kushanda zvakanaka uye kunaka kwekushandisa.
