I-fiber lasers ilandisa ngesabelo esandayo sama-lasers ezimboni unyaka nonyaka ngenxa yesakhiwo sawo esilula, izindleko eziphansi, ukusebenza kahle kokuguqulwa kwe-electro-optical, kanye nemiphumela emihle yokukhipha. Ngokwezibalo, ama-fiber lasers abalelwa ku-52.7% wemakethe ye-laser yezimboni ngo-2020.
Ngokusekelwe ezicini ze-beam yokukhipha, ama-fiber lasers angahlukaniswa ngezigaba ezimbili:i-laser eqhubekayofuthii-pulse laser. Yimuphi umehluko wezobuchwepheshe phakathi kwalokhu okubili, futhi yiziphi izimo zohlelo lokusebenza ngasinye ezilungele? Okulandelayo ukuqhathanisa okulula kwezinhlelo zokusebenza ezimweni ezijwayelekile.
Njengoba igama liphakamisa, ukuphuma kwe-laser nge-fiber laser eqhubekayo kuyaqhubeka, futhi amandla agcinwa ezingeni elimisiwe. Lawa mandla angamandla alinganiselwe we-laser.Inzuzo ye-fiber lasers eqhubekayo ukusebenza okuzinzile kwesikhathi eside.
I-laser ye-pulse laser "iphakathi". Yebo, lesi sikhathi sesikhashana sivame ukuba sifushane kakhulu, ngokuvamile silinganiswa ngama-milliseconds, ama-microseconds, noma ama-nanoseconds nama-piccoseconds. Uma kuqhathaniswa ne-laser eqhubekayo, ukuqina kwe-pulse laser kushintsha njalo, ngakho-ke kukhona imiqondo ye-"crest" kanye "nomkhombe".
Ngokushintshwa kwe-pulse modulation, i-pulsed laser ingakhululwa ngokushesha futhi ifinyelele amandla aphezulu endaweni ephakeme, kodwa ngenxa yokuba khona komkhombe, amandla ajwayelekile aphansi kakhulu.Kungacatshangwa ukuthi uma amandla ajwayelekile afana, ukuphakama kwamandla we-laser ye-pulse kungaba kukhulu kakhulu kune-laser eqhubekayo, kufinyelele amandla amakhulu kune-laser eqhubekayo, ebonakala ekhonweni elikhulu lokungena ukucubungula insimbi. Ngesikhathi esifanayo, Ifanele futhi izinto ezizwela ukushisa ezingakwazi ukumelana nokushisa okuphezulu okuqhubekayo, kanye nezinye izinto ezibonisa ukukhanya okuphezulu.
Ngokusebenzisa izici zamandla okukhiphayo kokubili, singakwazi ukuhlaziya umehluko wohlelo lokusebenza.
Ama-laser we-CW fiber ngokuvamile afaneleka:
1. Ukucutshungulwa kwemishini emikhulu, njengemishini yemoto neyomkhumbi, ukusika nokucubungula amapuleti amakhulu ensimbi, nezinye izikhathi zokucubungula ezingazweli emiphumeleni yokushisa kodwa ezizwela kakhulu izindleko.
2. Isetshenziswa ekusikeni kokuhlinzwa kanye nokuhlangana emkhakheni wezokwelapha, njenge-hemostasis ngemva kokuhlinzwa, njll.
3. Isetshenziswa kakhulu ezinhlelweni zokuxhumana zefiber optical zokudlulisa isignali nokukhulisa, ngokuzinza okuphezulu nomsindo wesigaba esiphansi
4. Isetshenziswa ezinhlelweni ezifana nokuhlaziywa kwe-spectral, ukuhlolwa kwe-atomic physics kanye ne-lidar emkhakheni wocwaningo lwesayensi, ihlinzeka ngamandla aphezulu kanye nokuphuma kwe-laser kwekhwalithi ephezulu.
Ama-laser we-pulsed fiber ngokuvamile afaneleka:
1. Ukucutshungulwa okunembayo kwezinto ezingakwazi ukumelana nokushisa okuqinile noma izinto eziphukayo, njengokucutshungulwa kwama-chips kagesi, ingilazi yobumba, nezingxenye zebhayoloji yezokwelapha.
2. Izinto ezibonakalayo zinokubonakala okuphezulu futhi zingalimaza kalula ikhanda le-laser ngokwayo ngenxa yokucabangela. Isibonelo, ukucutshungulwa kwezinto zethusi ne-aluminium
3. Ukwelashwa kwendawo noma ukuhlanzwa kwengaphandle lama-substrates awonakaliswa kalula
4. Izimo zokucubungula ezidinga amandla aphezulu esikhathi esifushane kanye nokungena okujulile, njengokusika kwepuleti eliwugqinsi, ukumba izinto zensimbi, njll.
5. Izimo lapho ama-pulses kudingeka asetshenziswe njengezici zesignali. Okufana nokuxhumana kwefiber optical kanye nezinzwa zefiber optical, njll.
6. Isetshenziswa emkhakheni we-biomedical ukuhlinzwa kwamehlo, ukwelashwa kwesikhumba nokusika izicubu, njll., ngekhwalithi ephezulu ye-beam nokusebenza kokushintshashintsha
7. Ekunyatheliseni kwe-3D, izingxenye zensimbi ezikhiqizwa ngokunemba okuphezulu kanye nezakhiwo eziyinkimbinkimbi zingafinyelelwa
8. Izikhali ze-laser ezithuthukisiwe, njll.
Kunomehluko othile phakathi kwe-pulsed fibre lasers kanye nama-laser fibre aqhubekayo ngokwemigomo, izici zobuchwepheshe kanye nokusetshenziswa, futhi ngayinye ifanele izikhathi ezahlukene. Ama-laser e-fiber e-pulsed afanele izinhlelo zokusebenza ezidinga amandla aphezulu nokusebenza kokushintshashintsha, njengokucutshungulwa kwezinto kanye ne-bio-medicine, kuyilapho ama-laser e-fiber eqhubekayo afanele izinhlelo zokusebenza ezidinga ukuzinza okuphezulu nekhwalithi ephezulu ye-beam, njengokuxhumana nocwaningo lwesayensi. Ukukhetha uhlobo olulungile lwe-fiber laser ngokusekelwe ezidingweni ezithile kuzosiza ukuthuthukisa ukusebenza kahle komsebenzi kanye nekhwalithi yohlelo lokusebenza.
