I-1.i-disc laser
Isindululo soyilo loyilo lweDiski Laser sisonjululwe ngokufanelekileyo ingxaki yefuthe lobushushu bee-laser zombuso oqinileyo kwaye safumana indibaniselwano egqibeleleyo yamandla omndilili ophezulu, amandla aphezulu aphezulu, ukusebenza kakuhle okuphezulu, kunye nomgangatho ophezulu we-laser yelizwe eliqinileyo.Iilaser zedisk ziye zaba ngumthombo omtsha wokukhanya welaser ongenakuphinda uphinde usetyenziswe kumacandelo eemoto, iinqanawa, oololiwe, ukuhamba ngenqwelomoya, amandla kunye namanye amasimi.Itekhnoloji yangoku ye-laser ye-laser ye-high-power inamandla amakhulu e-16 kilowatts kunye nomgangatho we-beam ye-8 mm milliradians, eyenza i-robot laser ye-remote welding kunye ne-laser-fomati enkulu yokusika isantya esiphezulu, ivula amathuba abanzi e-laser-state lasers intsimi yeamandla aphezulu laser processing.Imarike yesicelo.
Izinto eziluncedo zedisc lasers:
1. Ubume bemodyuli
I-disc laser ithatha isakhiwo semodyuli, kwaye imodyuli nganye inokutshintshwa ngokukhawuleza kwisayithi.Inkqubo yokupholisa kunye nenkqubo yesikhokelo sokukhanya idibaniswe kunye nomthombo we-laser, kunye nesakhiwo esincinci, unyawo oluncinci kunye nokufakwa ngokukhawuleza kunye nokuchithwa.
2. Umgangatho ogqwesileyo we-beam kunye nomgangatho
Zonke ii-laser zediski ze-TRUMPF ngaphezulu kwe-2kW zinemveliso yeparamitha ye-beam (BPP) esemgangathweni kwi-8mm / mrad.I-laser ayiguqukiyo kwiinguqu kwimodi yokusebenza kwaye iyahambelana nazo zonke ii-optics ze-TRUMPF.
3. Ekubeni ubukhulu bebala kwi-disc laser bukhulu, ukuxinana kwamandla optical kunyamezelwe yinto nganye ye-optical encinci.
Umda womonakalo we-optical element coating udla ngokuba malunga ne-500MW / cm2, kunye nomonakalo we-quartz yi-2-3GW / cm2.Ubuninzi bamandla kwi-TRUMPF disk laser resonant cavity ngokuqhelekileyo bungaphantsi kwe-0.5MW / cm2, kwaye ubuninzi bamandla kwi-coupling fiber bungaphantsi kwe-30MW / cm2.Ubuninzi bamandla obuphantsi obunjalo abuyi kubangela umonakalo kumacandelo e-optical kwaye akuyi kuvelisa imiphumo engabonakaliyo, ngaloo ndlela iqinisekisa ukuthembeka kokusebenza.
4. Yamkela inkqubo yolawulo lwengxelo yexesha langempela lelaser.
Inkqubo yolawulo lwengxelo yexesha lokwenyani inokugcina amandla afikelela kwi-T-piece ezinzileyo, kwaye iziphumo zokusetyenzwa zinokuphinda-phinda okubalaseleyo.Ixesha lokufudumala kwe-disc laser liphantse lizero, kwaye uluhlu lwamandla ahlengahlengiswayo luyi-1% -100%.Ekubeni i-laser ye-disc isombulula ngokupheleleyo ingxaki ye-lens ye-thermal, amandla e-laser, ubungakanani bebala, kunye ne-angle yokwahlukana kwe-beam izinzile ngaphakathi kulo lonke uluhlu lwamandla, kwaye i-wavefront ye-beam ayiphazamisi.
5. I-fiber optical ingaba yiplagi-kunye-play ngelixa i-laser iqhubeka nokusebenza.
Xa i-fiber optical ethile ingaphumeleli, xa utshintshela i-fiber optical, kufuneka uvale kuphela indlela ye-fiber optical ngaphandle kokuvala, kunye nezinye iifiber zamehlo zingaqhubeka nokukhupha ukukhanya kwe-laser.Ukutshintshwa kwefayibha ye-Optical kulula ukuyisebenzisa, iplagi kunye nokudlala, ngaphandle kwezixhobo okanye ukulungiswa kokulungelelaniswa.Kukho isixhobo sokukhusela uthuli emnyango wesitrato ukukhusela ngokungqongqo uthuli ekungeneni kwindawo yecandelo le-optical.
6. Ikhuselekile kwaye ithembekile
Ngexesha lokucutshungulwa, nokuba ukukhutshwa kwezinto ezicutshungulwayo kuphezulu kangangokuba ukukhanya kwelaser kubonakaliswe kwakhona kwi-laser, akuyi kuba nampembelelo kwi-laser ngokwayo okanye kwisiphumo sokusetyenzwa, kwaye akuyi kubakho zithintelo ekusetyenzweni kwezinto okanye ubude befiber.Ukhuseleko lokusebenza ngelaser luwongwe ngesiqinisekiso sokhuseleko saseJamani.
7. Imodyuli yokumpompa i-diode ilula kwaye ikhawuleza
Uluhlu lwe-diode olufakwe kwimodyuli yokumpompa nayo yeyokwakhiwa kweemodyuli.Iimodyuli ze-Diode zinobomi obude benkonzo kwaye ziqinisekisiwe iminyaka eyi-3 okanye iiyure ezingama-20,000.Akukho xesha lokuphumla lifunekayo nokuba kukutshintshwa okucwangcisiweyo okanye ukutshintshwa kwangoko ngenxa yokusilela ngequbuliso.Xa imodyuli ingaphumeleli, inkqubo yokulawula iya kubetha kwaye ikhulise ngokuzenzekelayo i-current yezinye iimodyuli ngokufanelekileyo ukugcina amandla okuphuma kwe-laser rhoqo.Umsebenzisi unokuqhubeka nokusebenza ishumi okanye iiyure ezininzi.Ukutshintsha iimodyuli zediode zokupompa kwindawo yokuvelisa kulula kakhulu kwaye akufuni uqeqesho lwabaqhubi.
I-Fiber lasers, njengezinye iilaser, zenziwe ngamacandelo amathathu: i-ain medium (doped fiber) enokuvelisa iifotoni, i-optical resonant cavity evumela iiphotons ukuba zityiswe kwaye zandiswe ngokuvakalayo kwindawo yokuzuza, kunye nomthombo wempompo ovuyisayo. photon utshintsho.
Iimpawu: 1. I-fiber ye-Optical inomlinganiselo ophezulu "wendawo / umthamo", isiphumo esihle sokutshatyalaliswa kobushushu, kwaye inokusebenza ngokuqhubekayo ngaphandle kokupholisa ngenkani.2. Njengomthombo we-waveguide, i-fiber optical ine-diameter encinci ye-core kwaye ijwayele ukuxinana kwamandla aphezulu ngaphakathi kwefayibha.Ke ngoko, iilaser zefiber zinoguqulo oluphezulu olusebenzayo, umda ophantsi, inzuzo ephezulu, kunye nobubanzi obumxinwa bomgca, kwaye zahlukile kwifiber optical.Ilahleko yokudibanisa incinci.3. Ngenxa yokuba i-fibers optical fibers ine-flexibility efanelekileyo, i-fiber lasers incinci kwaye iguquguqukayo, i-compact kwisakhiwo, indleko-esebenzayo, kwaye kulula ukudibanisa kwiinkqubo.4. Ifiber ye-Optical nayo ineeparamitha ezininzi ezinokuqhutywa kunye nokukhetha, kwaye inokufumana uluhlu olubanzi lokulungisa, ukusasazwa okulungileyo kunye nozinzo.
Ukuhlelwa kweFayibha laser:
1. Umhlaba onqabileyo we-doped fiber laser
2. Iziqalelo zomhlaba ezinqabileyo ezifakwe kwimicu ebonisa ukukhula esebenzayo ngoku ngokwentelekiso: erbium, neodymium, praseodymium, thulium, kunye neytterbium.
3. Isishwankathelo se-fiber evuselelwe i-Raman yokusabalalisa i-laser: I-laser ye-Fiber ngokuyimfuneko i-wavelength converter, enokuguqula i-wavelength yepompo ibe kukukhanya kwe-wavelength ethile kwaye iyikhuphe ngendlela ye-laser.Ukusuka kumbono womzimba, umgaqo wokuvelisa ukukhanya kokukhanya kukubonelela ngezinto zokusebenza ngokukhanya kwe-wavelength enokuthi ikwazi ukuyifumana, ukwenzela ukuba izinto zokusebenza zikwazi ukufumana amandla ngokufanelekileyo kwaye zisebenze.Ngoko ke, kuxhomekeke kwi-doping material, i-absorption wavelength ehambelanayo nayo ihluke, kunye nempompo Iimfuno zokukhanya kwe-wavelength nazo zihluke.
2.3 I-laser ye-semiconductor
I-laser ye-semiconductor yavuyiswa ngempumelelo kwi-1962 kwaye yafumana umphumo oqhubekayo kwiqondo lokushisa lokushisa kwi-1970. Kamva, emva kokuphuculwa, i-laser ye-heterojunction ephindwe kabini kunye ne-laser diodes ene-stripe-structured laser diodes (i-Laser diodes) yaphuhliswa, esetyenziswa ngokubanzi kwi-optical fiber communications, i-optical discs. izishicileli zelaser, izikena zelaser, kunye nezikhombisi zelaser (izikhombisi zelaser).Ngoku zezona laser eziveliswa kakhulu.Iinzuzo ze-laser diode zezi: ukusebenza kakuhle, ubungakanani obuncinci, ubunzima obulula kunye nexabiso eliphantsi.Ngokukodwa, ukusebenza kakuhle kwe-multiple quantum well type yi-20 ~ 40%, kwaye uhlobo lwe-PN lufikelela kwii-15% ~ 25% ezininzi.Ngamafutshane, ukusebenza kakuhle kwamandla yeyona nto inkulu.Ukongeza, i-wavelength yayo eqhubekayo yokuphuma igubungela uluhlu olusuka kwi-infrared ukuya ekukhanyeni okubonakalayo, kunye neemveliso ezine-optical pulse output ukuya kwi-50W (pulse width 100ns) nazo ziye zathengiswa.Ingumzekelo we-laser elula kakhulu ukuyisebenzisa njenge-lidar okanye umthombo wokukhanya wokuvuselela.Ngokutsho kwethiyori yebhendi yamandla yezinto eziqinileyo, amanqanaba amandla eelektroni kwizinto zesemiconductor enza iibhendi zamandla.Amandla aphezulu liqela le-conduction, amandla aphantsi elinye libhendi ye-valence, kwaye amaqela amabini ahlulwe yibhendi engavumelekanga.Xa izibini ze-electron-hole ezingekho-equilibrium zifakwe kwi-semiconductor recombine, amandla akhutshiweyo akhutshwe ngendlela ye-luminescence, eyona nto i-luminescence yokubuyisela abathwali.
Izinto eziluncedo ze-laser semiconductor: ubungakanani obuncinci, ubunzima obulula, ukusebenza okuthembekileyo, ukusetyenziswa kwamandla aphantsi, ukusebenza kakuhle okuphezulu, njl.
