Ukusika iFayibha laser kunye Medical
Ifayibha laser ukusika kunye neyeza, ifayibha laser ukusika umatshini ifayibha doped ifayibha ngokwayo njengento esebenzayo, kunye nefayibha laser ukusika umatshini ngokwawo, kodwa udlala indima yesikhokelo amaza esomeleleyo-state laser.I-resonator, iqulethe into esebenzayo, umthombo wempompo amacandelo amathathu asisiseko.Kwiminyaka yakutshanje, iilaser zefiber kwiinkalo zemizi-mveliso ukongeza kuluhlu olubanzi lwezicelo, kunye nokwanda kokuthandwa kwezonyango.
I-Fiber Technology Centre, iYunivesithi yaseSydney, e-Australia (OFT C) yaseStuart Jackson yathi: "Umatshini wokusika i-fiber laser kwizicelo zotyando, kubalulekile ukudibanisa i-laser, ukugcinwa okuncinci, ukusebenza kakuhle okuphezulu kunye neempawu ezintle ze-thermal ze-fiber laser.ukubenza bafaneleke ngokukodwa kwizicelo zotyando ngenxa yokuba basebenzisa i-diode-pumped, ngoko i-compact kakhulu.Imilo yeFayibha kunemathiriyeli yelaser yelizwe eqinileyo iphezulu kuba yenza lula imfuno yokuhanjiswa kwefayibha eyongezelelweyo, ngokwenjenjalo yehlisa iindleko kwaye yehlisa ukuNcophelela kwenkqubo”.
Umatshini wokusika we-Fiber laser ngo-1963 ngu-Elias Spritzer owenziwe.Ngaphambi kokuba ekugqibeleni ungene kusetyenziso lwezorhwebo, emva kweminyaka emibini yophuhliso lwexesha.Kwangoko, ukusetyenziswa kwe-single-mode diode laser impompo, kuphela amashumi emitha yeemililitha.Kodwa inabasebenzisi abaninzi abasenomtsalane ngenxa yenzuzo yabo ephezulu, inokwenza uninzi lwemowudi enye eqhubekayo yokusebenza kweeyoni zomhlaba ezinqabileyo, eyi-crystal laser ayinakufezekiswa.Ngo-1990, i-fiber lasers ukufikelela kwinqanaba lokuphuma kwe-leap-watt, emva koko, ingxelo ye-erbium-doped fiber laser output power up 4 W, olu phuhliso namhlanje sibona amandla e-10 W kunye nesiseko esiphezulu se-fiber lasers isiseko.
Kumatshini wokusika i-fiber laser, i-fiber ngokwayo isebenza njenge-resonant cavity.Ezi zixhobo ziquka ngokubanzi i-erbium doped imowudi enye engundoqo ytterbium (okanye iindibaniselwano zayo), okanye into enqabileyo yomhlaba.Amandla asuka kumthombo wokukhanya okuqinileyo, adityaniswa nokugqunywa kwefayibha, emva koko angene kumbindi, impompo iphefumle iiathom.Kwicandelo lezonyango, ubude bamaza bufuneka kakhulu zezi: 1.3μm band for umfanekiso, 1.5μm (incopho yokufunxa amanzi) -4μm band yotyando, ukusuka kuluhlu lwamandla eemilitha ukuya ngaphezulu kwe-100 W.
UJackson uthe: "Ukusetyenziswa kwe-laser ye-CW, usetyenziso lwe-biomedical, ngakumbi nayiphi na i-laser ephezulu ye-CW, inokuxhamla kumatshini wokusika we-fiber laser ngumatshini wokusika we-fiber laser ubonelela ngokusebenza okuphezulu, uluhlu olubanzi lokuguqula, kunye nesiphumo sonke.uluhlu lwamandla lunenzuzo yomgangatho ongcono we-beam, ngokukodwa obalaseleyo;ukuze i-fiber lasers uluhlu lwezicelo zonyango luqhubeka nokwandisa.“
