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 eqhubekayokwayeipulse 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 nkulu kakhulu kune-laser eqhubekayo, ukuphumeza ubuninzi bamandla ngaphezu kwe-laser eqhubekayo, ebonakaliswa kumandla okungena okukhulu kokungena. processing metal. 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.
Iilaser ze-CW fiber 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 wee-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.
