-I-fiber laosers zempompo
I-Laser DeodsNjengomthombo wempompo:I-fiber lairs isebenzisa i-laser ye-lamer rood njengomthombo wabo wempompo ngenxa yokusebenza kwabo, ubungakanani be-compact, kunye nokukwazi ukuvelisa ukukhanya kwe-fiber yokufumana i-fiber yokufumana ifibre. Ukukhetha i-Laser Diode Wavelength ibalulekile; Umzekelo, idepant eqhelekileyo kwi-fiber lars yi-ytterbium (yb), enento ebonakalayo i-976 nm. Ke ngoko, i-laser Deods ekutyibilikeni okanye kufutshane nale wavenct ekhethwayo ukuba ipolise i-fiber i-fiber i-fir.
Uyilo lwe-fible-cled fible:Ukonyusa ukusebenza kwenqanaba lokukhanya kwi-pump ye-pump ye-pump ye-pumps, i-fiber Lasers ihlala isebenzisa uyilo lwe-fible. I-Inner Core iconjululwe nge-laser esebenzayo (umzekelo, yb), ngelixa i-over, i-varding ye-Cladding ikhokela isibane sempompo. I-CORE ifumana ukukhanya kwempompo kwaye ivelise i-laser yesenzo, ngelixa i-gardding ivumela inani elikhulu kakhulu lempompo yokukhanya ukunxibelelana ne-core, ekwandiseni ukusebenza kakuhle.
I-Waveled Dictional kunye neNtloko yeSebe leMfundo: Ukupeyitha okusebenzayo akufuneki nje ukukhetha i-laves ye-lavees kunye ne-waveeth efanelekileyo kodwa ikwandelisa ukusebenza ngokukuko phakathi kweedayinti kunye nefibre. Oku kubandakanya ukulungelelanisa ngononophelo kunye nokusetyenziswa kwamacandelo obomi njengeelensi kunye nabatshatileyo ukuqinisekisa ukuba ukukhanya kwempompo igcinwe kwi-fiber core okanye ivale.
-Abahambisi boqinileyoIimfuneko zomthombo wePump
Impompo ye-optical:Ngaphandle kweLaser Dedos, i-Lasers eqinileyo-yombuso (kubandakanya ii-lers ze-bulk njenge-ND: Yag) inokuthi iphinde iphindwe nge-flash izibane okanye izibane ze-ARC. Ezi zibane zikhupha umzobo obanzi wokukhanya, inxenye yenxalenye ehambelana neebhendi ze-laser. Ngelixa i-laser diode impompo, le ndlela inokubonelela ngamandla aphezulu equla kakhulu, iyenza ilungele izicelo ezifuna amandla amakhulu.
Isimo somthombo wempompo:Uqwalaselo lomthombo wempompo kwi-lasers eqinileyo-yombuso inokuchaphazela kakhulu ukusebenza kwabo. Ukuphelisa ukupompa kunye nokumpompa ngecala. Ukuphela kwempompo, apho ukukhanya kwempompo kujolise kwi-Axis ye-Optical ye-laser, inikezela ngaphezulu phakathi kokukhanya kwempompo kunye nendlela ekhokelela ekusebenzeni kakuhle. Ukumpompozela ecaleni, ngelixa kunokwenzeka ukuba kungasebenzi kakuhle, kulula kwaye kunokubonelela ngamandla aphezulu kakhulu kwiintonga ezinkulu zedayimitha okanye ii-slabs.
Ulawulo lwe-Thermal:Zombini i-fiber kunye neendlela eziqinileyo ze-State zifuna ulawulo olusebenzayo lwe-thermal ukujongana nobushushu obuveliswa yimithombo yempompo. Kwi-fiber lars, indawo eyandisiweyo yoGawulayo yeFiber kwi-Shift. Kwiindlela eziqinileyo-zikarhulumente, iinkqubo zokupholisa (ezinjengokupholisa amanzi) ziyimfuneko ukugcina umsebenzi uzinzo kwaye kuthintele i-ilensile ye-thermal okanye monakalo kwi-laser ephakathi.
