1. i-laser yediski
Isiphakamiso soyilo lweDisk Laser sisombulule ngempumelelo ingxaki yempembelelo yobushushu yee-laser eziqinileyo kwaye safumana indibaniselwano egqibeleleyo yamandla aphakathi aphezulu, amandla aphezulu, ukusebenza kakuhle, kunye nomgangatho ophezulu wee-laser eziqinileyo. Ii-laser zeDisk ziye zaba ngumthombo omtsha wokukhanya kwe-laser ongenakutshintshwa wokucubungula kwiinkalo zeemoto, iinqanawa, oololiwe, iindiza, amandla kunye nezinye iindawo. Itekhnoloji yangoku ye-laser yediski enamandla aphezulu inamandla aphezulu ee-kilowatts ezili-16 kunye nomgangatho we-beam we-8 mm milliradians, evumela i-robot laser remote welding kunye ne-laser enkulu yefomathi ephezulu yokusika, ivula amathuba abanzi ee-laser eziqinileyo kwicandelo leukucubungula nge-laser enamandla aphezuluImakethi yesicelo.
Iingenelo ze-laser zediski:
1. Ulwakhiwo lweModular
I-laser yediski isebenzisa isakhiwo esimiselweyo, kwaye imodyuli nganye inokutshintshwa ngokukhawuleza kwindawo. Inkqubo yokupholisa kunye nenkqubo yesikhokelo sokukhanya zidityaniswe nomthombo we-laser, kunye nesakhiwo esincinci, indawo encinci kunye nokufakwa kunye nokulungiswa kwengxaki ngokukhawuleza.
2. Umgangatho ogqwesileyo wemitha kunye nomgangatho omiselweyo
Zonke ii-laser zediski ze-TRUMPF ezingaphezulu kwe-2kW zinemveliso yepharamitha ye-beam (BPP) emiselweyo kwi-8mm/mrad. I-laser ayiguquguquki kutshintsho kwindlela yokusebenza kwaye iyahambelana nazo zonke ii-optics ze-TRUMPF.
3. Ekubeni ubungakanani bebala kwi-laser yediski bukhulu, uxinano lwamandla e-optical olunyanyekelwa yi-element nganye ye-optical luncinci.
Umlinganiselo womonakalo we-optical element coating uhlala malunga ne-500MW/cm2, kwaye umda womonakalo we-quartz yi-2-3GW/cm2. Uxinano lwamandla kwi-TRUMPF disk laser resonant cavity luhlala lungaphantsi kwe-0.5MW/cm2, kwaye uxinano lwamandla kwi-coupling fiber lungaphantsi kwe-30MW/cm2. Uxinano lwamandla aphantsi ngolo hlobo aluyi kubangela umonakalo kwi-optical components kwaye aluyi kuvelisa iziphumo ezingezizo ezomgca, ngaloo ndlela kuqinisekiswa ukuthembeka kokusebenza.
4. Sebenzisa inkqubo yolawulo lwempendulo ngexesha langempela yamandla e-laser.
Inkqubo yokulawula impendulo ngexesha langempela inokugcina amandla efikelela kwi-T-piece izinzile, kwaye iziphumo zokucubungula zinokuphindaphindwa kakuhle. Ixesha lokufudumeza kwangaphambili kwe-disc laser liphantse libe yi-zero, kwaye uluhlu lwamandla oluhlengahlengiswayo luyi-1%–100%. Ekubeni i-disc laser isombulula ngokupheleleyo ingxaki yesiphumo se-thermal lens, amandla e-laser, ubungakanani bebala, kunye ne-angle yokwahlukana kwe-beam zizinzile ngaphakathi koluhlu lwamandla lonke, kwaye i-wavefront ye-beam ayiphazami.
5. I-optical fiber ingafakwa kwi-plug-and-play ngelixa i-laser iqhubeka nokusebenza.
Xa ifayibha ethile ye-optical ingaphumeleli, xa utshintsha ifayibha ye-optical, udinga kuphela ukuvala indlela ye-optical yefayibha ye-optical ngaphandle kokuvala, kwaye ezinye iifayibha ze-optical zinokuqhubeka nokukhupha ukukhanya kwe-laser. Ukutshintshwa kwefayibha ye-optical kulula ukuyisebenzisa, ukuyixhuma nokuyidlala, ngaphandle kwezixhobo okanye ukulungiswa kokulungelelaniswa. Kukho isixhobo esingenathuli emnyango wesitalato ukuthintela ngokungqongqo uthuli ukuba lungangeni kwindawo yecandelo le-optical.
6. Ikhuselekile kwaye ithembekile
Ngexesha lokucubungula, nokuba ukukhupha kwezinto ezicutshungulwayo kuphezulu kangangokuba ukukhanya kwelaser kubuyiselwa kwilaser, akuyi kuba nafuthe kwilaser ngokwayo okanye kwisiphumo sokucubungula, kwaye akuyi kubakho mingcele ekucutshungulweni kwezinto okanye kubude befayibha. Ukhuseleko lokusebenza kwelaser lunikwe isatifiketi sokhuseleko saseJamani.
7. Imodyuli ye-diode yokupompa ilula kwaye ikhawuleza
I-diode array efakwe kwi-pumping module nayo yenziwe nge-modular. Ii-Diode array modules zinobomi obude benkonzo kwaye ziqinisekisiwe iminyaka emi-3 okanye iiyure ezingama-20,000. Akukho xesha lokungasebenzi lifunekayo nokuba kukutshintshwa okucwangcisiweyo okanye ukutshintshwa kwangoko ngenxa yokusilela ngequbuliso. Xa i-module isilela, inkqubo yolawulo iya kulumkisa kwaye inyuse ngokuzenzekelayo amandla ezinye ii-modules ngokufanelekileyo ukugcina amandla okukhupha i-laser engaguquki. Umsebenzisi unokuqhubeka esebenza iiyure ezilishumi okanye amashumi amabini. Ukutshintsha ii-pomping diode modules kwindawo yemveliso kulula kakhulu kwaye akufuneki qeqesho lomqhubi.
Iilaser zefayibha, njengezinye iilaser, zenziwe ngamacandelo amathathu: i-gain medium (ifayibha exutyiweyo) enokuvelisa ii-photons, i-optical resonant cavity evumela ii-photons ukuba zibuyiselwe kwaye zikhuliswe ngokubonakalayo kwi-gain medium, kunye nomthombo wepompo ovuselela utshintsho lwe-photon.
Iimpawu: 1. I-Optical fiber inomlinganiselo ophezulu "womphezulu/umthamo", isiphumo esihle sokusasaza ubushushu, kwaye ingasebenza ngokuqhubekayo ngaphandle kokupholisa okunyanzelekileyo. 2.

Ngokwembono ebonakalayo, umgaqo wokuvelisa ukukhanya okukhulayo kukubonelela ngezinto zokusebenza ngokukhanya kwe-wavelength enokufunxa, ukuze izinto ezisebenzayo zikwazi ukufunxa amandla ngempumelelo kwaye zisebenze. Ke ngoko, ngokuxhomekeke kwizinto ezisebenzisa i-doping, ubude be-wavelength obuhambelanayo nabo bahlukile, kwaye i-pump Iimfuneko ze-wavelength yokukhanya nazo zahlukile.
2.3 I-laser ye-semiconductor
I-laser ye-semiconductor yavuselelwa ngempumelelo ngo-1962 yaza yafumana i-output eqhubekayo kubushushu begumbi ngo-1970. Kamva, emva kokuphuculwa, ii-laser ezimbini ze-heterojunction kunye nee-stripe-structured laser diodes (ii-Laser diodes) zaphuhliswa, ezisetyenziswa kakhulu kunxibelelwano lwe-optical fiber, ii-optical discs, ii-laser printers, ii-laser scanners, kunye nee-laser pointers (ii-laser pointers). Okwangoku zezona laser ziveliswa kakhulu. Iingenelo ze-laser diodes zezi: ukusebenza kakuhle, ubungakanani obuncinci, ubunzima obulula kunye nexabiso eliphantsi. Ngokukodwa, ukusebenza kakuhle kohlobo lwe-multiple quantum well yi-20~40%, kwaye uhlobo lwe-PN lufikelela kwiipesenti ezili-15%~25. Ngamafutshane, ukusebenza kakuhle kwamandla aphezulu lolona phawu lwayo lukhulu. Ukongeza, ubude bayo obuqhubekayo bokuphuma bugubungela uluhlu ukusuka kwi-infrared ukuya ekukhanyeni okubonakalayo, kwaye iimveliso ezine-optical pulse output ukuya kwi-50W (ububanzi be-pulse 100ns) nazo ziye zathengiswa. Ngumzekelo we-laser elula kakhulu ukuyisebenzisa njengomthombo wokukhanya we-lidar okanye we-excitation. Ngokwethiyori yebhendi yamandla yezinto eziqinileyo, amanqanaba amandla ee-electron kwizixhobo ze-semiconductor enza iibhendi zamandla. Eyeyona yamandla aphezulu yibhendi yokuqhuba, eyeyona yamandla aphantsi yibhendi ye-valence, kwaye ezi bhendi zimbini zahlulwe yibhendi engavumelekanga. Xa ii-pair ze-electron-hole ezingezizo ezokulingana zingeniswa kwi-semiconductor recombine, amandla akhutshiweyo akhutshwa ngendlela yokukhanya, okukukhanya okuphinda kuhlangane kwabathwali.
