Usetyenziso lweLaser kunye noHlelo

1.idiski 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 yeukusetyenzwa kwelaser enamandla amakhulu. Imarike yesicelo.

Izinto eziluncedo kwii-disc 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 zokucubungula 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.

2.2Ifayibha laser

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.
