Yintoni iCW DPSS laser? Inkcazo Uqhekeko

I-Wave eqhubekayo (CW):Oku kubhekiselele kwindlela yokusebenza yelaser. Kwimo ye-CW, i-laser ikhupha ukukhanya okungaguqukiyo, okungaguqukiyo, ngokuchaseneyo ne-laser ye-pulsed ekhupha ukukhanya ngokugqabhuka. Iilaser ze-CW zisetyenziswa xa ukukhanya okuqhubekayo, okungaguqukiyo kufuneka, njengokusika, ukuwelda, okanye ukukrola izicelo.

Ukumpompa iDiode:Kwii-laser ze-diode-pumped lasers, amandla asetyenziselwa ukuvuyisa i-laser medium anikezelwa yi-semiconductor laser diode. Ezi diode zikhupha ukukhanya okufunxwa yilaser medium, kuchulumancisa iiathom ezingaphakathi kuyo kwaye zibavumele ukuba bakhuphe ukukhanya okuhambelanayo. Ukumpompa kwe-Diode kusebenza kakuhle kwaye kuthembekile xa kuthelekiswa neendlela zakudala zokumpompa, njengezibane ezikhanyayo, kwaye zivumela ukuyila kwe-laser edibeneyo kunye neyomelele.

I-Solid-State Laser:Igama elithi "solid-state" libhekisa kudidi lwendlela yokuzuza esetyenziswa kwilaser. Ngokungafaniyo negesi okanye iilaser zolwelo, iilaser eziqinileyo zisebenzisa izinto eziqinileyo njengesixhobo esiphakathi. Esi siphakathi siqhele ukuba yikristale, njengeNd:YAG (Neodymium-doped Yttrium Aluminium Garnet) okanye iRuby, efakwe izinto ezinqabileyo zomhlaba ezenza ukuveliswa kokukhanya kwelaser. Ikristale ene-doped yiyo eyandisa ukukhanya ukuvelisa i-laser beam.

Ubude bamaza kunye nezicelo:I-laser ye-DPSS inokukhupha kumaza ahlukeneyo, kuxhomekeke kuhlobo lwemathiriyeli yedoping esetyenziswa kwikristale kunye noyilo lwelaser. Ngokomzekelo, ukucwangciswa kwe-laser ye-DPSS eqhelekileyo kusebenzisa i-Nd: YAG njengendlela yokuzuza ukuvelisa i-laser kwi-1064 nm kwi-infrared spectrum. Olu hlobo lwe-laser lusetyenziswa ngokubanzi kwizicelo zamashishini zokusika, ukuwelda, kunye nokumakisha izinto ezahlukeneyo.

Izinto eziluncedo:Iilaser ze-DPSS ziyaziwa ngomgangatho wazo ophezulu we-beam, ukusebenza kakuhle, kunye nokuthembeka. Zisebenza ngamandla kunee-laser zemveli eziqinileyo ezimpontshwa zizibane kwaye zinika ubomi obude bokusebenza ngenxa yokuqina kweelases zediode. Bayakwazi ukuvelisa imiqadi yelaser ezinzile kwaye ichanekile, ebalulekileyo kwiinkqubo ezineenkcukacha kunye nezichanekileyo.

Usetyenziso olungundoqo lwe-CW Diode Pumped Solid State Laser:

1.Laser Diamond Cutting:

I-laser ye-G2-A isebenzisa ulungelelwaniso oluqhelekileyo lokuphindaphinda kabini: i-infrared input beam kwi-1064 nm iguqulwa ibe yi-532-nm yamaza eluhlaza njengoko idlula kwi-crystal engabonakaliyo. Le nkqubo, eyaziwa ngokuba yi-frequency doubling okanye i-second harmonic generation (SHG), yindlela eyamkelwa ngokubanzi yokuvelisa ukukhanya kubude obufutshane bobude.

Ngokuphinda kabini ukuphindaphinda kokukhanya okuvela kwi-neodymium- okanye i-ytterbium-based 1064-nm laser, i-laser yethu ye-G2-A inokuvelisa ukukhanya okuluhlaza kwi-532 nm. Obu buchule bubalulekile ekudaleni iilaser eziluhlaza, ezidla ngokusetyenziswa kwizicelo ezisusela kwizikhombisi zelaser ukuya kwizixhobo ezintsonkothileyo zenzululwazi kunye nezamashishini, kwaye zikwadume kwindawo yokusika iLaser Diamond.
