I-Fiber lasers yenza isabelo esonyukayo se-laser yemizi-mveliso unyaka nonyaka ngenxa yesakhiwo sazo esilula, ixabiso eliphantsi, ukusebenza kakuhle kokuguqulwa kwe-electro-optical, kunye neziphumo ezilungileyo zemveliso. Ngokwezibalo, iifayibha lasers zibalelwa kwi-52.7% yentengiso yelaser yeshishini ngo-2020.
Ngokusekwe kwiimpawu zomqadi wokuphuma, iilaser zefiber zinokwahlulwa zibe ziindidi ezimbini:i-laser eqhubekayokwayei-pulse laser. Ziziphi iiyantlukwano zobuchwephesha phakathi kwezi zibini, kwaye zeziphi iimeko zesicelo ezifanelekileyo? Oku kulandelayo luthelekiso olulula lwezicelo kwiimeko eziqhelekileyo.
Njengoko igama libonisa, i-laser ye-laser ye-fiber laser eqhubekayo iyaqhubeka, kwaye amandla agcinwa kwinqanaba elimiselweyo. La mandla ngamandla alinganisiweyo e-laser.Inzuzo ye-fiber lasers eqhubekayo yintsebenzo yexesha elide elizinzileyo.
I-laser ye-laser ye-pulse "iphakathi". Ngokuqinisekileyo, eli xesha lihlala lifutshane kakhulu, lidla ngokulinganiswa kwii-milliseconds, ii-microseconds, okanye nakwii-nanoseconds kunye nee-picoseconds. Xa kuthelekiswa ne-laser eqhubekayo, ubukhulu be-laser ye-pulse buhlala buguquka, ngoko ke kukho iingcamango ze "crest" kunye ne "trough".
Ngokumodareyitha kwe-pulse, i-laser ye-pulsed inokukhutshwa ngokukhawuleza kwaye ifikelele kumandla aphezulu kwindawo ephezulu, kodwa ngenxa yobukho bomkhombe, amandla aphakathi aphantsi.Kucingelwa ukuba ukuba amandla aphakathi ayafana, amandla encopho ye-laser ye-pulse ingaba mkhulu kakhulu kune-laser eqhubekayo, ukuphumeza ubuninzi bamandla ngaphezu kwe-laser eqhubekayo, ebonakaliswa kumandla amakhulu okungena kokungena kwi-metal processing. Kwangaxeshanye, ikwafanelekile kwizinto ezingeva lubushushu ezingakwaziyo ukumelana nobushushu obuphezulu obuzinzileyo, kunye nezinye izinto ezibonisa ubushushu obuphezulu.
Ngokusebenzisa iimpawu zamandla emveliso yezi zibini, sinokuhlalutya ukungafani kwesicelo.
I-fiber lasers ze-CW zifanelekile ngokubanzi:
1. Ukucutshungulwa kwezixhobo ezinkulu, ezifana nemoto kunye noomatshini beenqanawa, ukusika kunye nokucutshungulwa kweepleyiti ezinkulu zetsimbi, kunye nezinye iziganeko zokucubungula ezingenakukhathazeka kwimiphumo ye-thermal kodwa zivakalelwa ngakumbi kwiindleko.
2. Isetyenziselwa ukusika utyando kunye ne-coagulation kwicandelo lezonyango, njenge-hemostasis emva kokuhlinzwa, njl.
3. Isetyenziswa ngokubanzi kwiinkqubo zonxibelelwano lwefiber optical ukuhanjiswa komqondiso kunye nokukhulisa, kunye nozinzo oluphezulu kunye nengxolo yenqanaba eliphantsi.
4. Isetyenziswe kwizicelo ezifana nohlalutyo lwe-spectral, iimvavanyo ze-atomic physics kunye ne-lidar kwintsimi yophando lwezenzululwazi, ukubonelela ngamandla aphezulu kunye nomgangatho ophezulu we-laser ophumayo.
Iilaser zefiber pulsed zihlala zifanelekile:
1. Ukuchaneka kokusetyenzwa kwemathiriyeli engakwaziyo ukumelana nefuthe elomeleleyo lobushushu okanye imathiriyeli enqabileyo, njengokusetyenzwa kweetshiphusi ze-elektroniki, iglasi yeceramic, kunye namalungu ebhayoloji yezonyango.
2. Izinto eziphathekayo zinokubonakala okuphezulu kwaye zingonakalisa ngokulula intloko ye-laser ngokwayo ngenxa yokucamngca. Ngokomzekelo, ukucutshungulwa kwezinto zobhedu kunye ne-aluminium
3. Unyango lomphezulu okanye ukucocwa komphandle we-substrates ezonakaliswe lula
4. Iimeko zokucutshungulwa ezifuna amandla aphezulu exesha elifutshane kunye nokungena okunzulu, njengokusika kweplate eshinyeneyo, ukugrumba izinto zetsimbi, njl.
5. Iimeko apho ii-pulses kufuneka zisetyenziswe njengeempawu zomqondiso. Njengonxibelelwano lwefiber optical kunye nezinzwa zefiber optical, njl.
6. Isetyenziswe kwintsimi ye-biomedical yokuhlinzwa kwamehlo, unyango lwesikhumba kunye nokusika izicubu, njl., kunye nomgangatho ophezulu we-beam kunye nokusebenza kwemodulation.
7. Kushicilelo lwe-3D, iinxalenye zetsimbi eziveliswa ngokuchaneka okuphezulu kunye nezakhiwo ezinzima zinokufezekiswa
8. Izixhobo eziphezulu ze-laser, njl.
Kukho umahluko phakathi kwe-laser fiber lasers kunye ne-fiber lasers eqhubekayo ngokwemigaqo, iimpawu zobugcisa kunye nokusetyenziswa, kwaye nganye ifanelekile kwizihlandlo ezahlukeneyo. I-laser fiber lasers ifanelekile kwizicelo ezifuna amandla aphezulu kunye nokusebenza kwemodyuli, njengokusetyenzwa kwezinto kunye ne-bio-medicine, ngelixa i-fiber lasers eqhubekayo ifanelekile kwizicelo ezifuna uzinzo oluphezulu kunye nomgangatho ophezulu we-beam, njengonxibelelwano kunye nophando lwezenzululwazi. Ukukhetha uhlobo oluchanekileyo lwe-fiber laser ngokusekelwe kwiimfuno ezithile kuya kunceda ukuphucula ukusebenza kakuhle kunye nomgangatho wesicelo.
