Ingabe idayimane ingasikwa nge-laser?
Yebo, ama-laser angasika amadayimane, futhi le ndlela isithandwa kakhulu embonini yamadayimane ngezizathu eziningana. Ukusika nge-laser kunikeza ukunemba, ukusebenza kahle, kanye nekhono lokwenza ukusika okuyinkimbinkimbi okunzima noma okungenakwenzeka ukukufeza ngezindlela zokusika zendabuko zemishini.
Iyiphi indlela yendabuko yokusika idayimane?
Inselele Yokusika Nokusaha Idayimane
Idayimane, njengoba iqinile, iphuka kalula, futhi izinzile ngamakhemikhali, ibeka izinselele ezinkulu ezinqubweni zokusika. Izindlela zendabuko, okuhlanganisa ukusika ngamakhemikhali kanye nokupholisha ngokomzimba, zivame ukuholela ezindleleni eziphezulu zomsebenzi kanye namazinga amaphutha, kanye nezinkinga ezifana nokuqhekeka, ama-chips, kanye nokuguguleka kwamathuluzi. Njengoba kunesidingo sokunemba kokusika kwezinga le-micron, lezi zindlela ziyasilela.
Ubuchwepheshe bokusika nge-laser buvela njengendlela engcono kakhulu, bunikeza ukusika okusheshayo, okuseqophelweni eliphezulu kwezinto eziqinile neziphukayo njengedayimane. Le ndlela inciphisa umthelela wokushisa, inciphisa ingozi yomonakalo, amaphutha njengokuqhekeka nokuqhekeka, futhi ithuthukisa ukusebenza kahle kokucubungula. Inesivinini esisheshayo, izindleko zemishini eziphansi, kanye namaphutha ancishisiwe uma kuqhathaniswa nezindlela ezenziwe ngesandla. Isixazululo se-laser esiyinhloko ekusikeni idayimane yi-I-DPSS (Isimo Esiqinile Esipompelwe yi-Diode) Nd: I-laser ye-YAG (i-Neodymium-doped Yttrium Aluminium Garnet), ekhipha ukukhanya okuluhlaza okungu-532 nm, okuthuthukisa ukunemba kokusika kanye nekhwalithi.
Izinzuzo ezi-4 ezinkulu zokusika idayimane nge-laser
01
Ukunemba Okungalingani
Ukusika nge-laser kuvumela ukusika okunembe kakhulu nokuyinkimbinkimbi, okuvumela ukudalwa kwemiklamo eyinkimbinkimbi ngokunemba okuphezulu kanye nokuchitha okuncane.
02
Ukusebenza Kahle Nesivinini
Le nqubo ishesha futhi isebenza kahle, inciphisa kakhulu izikhathi zokukhiqiza futhi yandisa umkhiqizo wabakhiqizi bedayimane.
03
Ukuguquguquka Kokuklama
Ama-laser anikeza ukuguquguquka kokukhiqiza uhla olubanzi lwezimo nemiklamo, evumela ukusika okuyinkimbinkimbi nokubucayi okungenakufezwa izindlela zendabuko.
04
Ukuphepha Okuthuthukisiwe Nekhwalithi
Ngokusika nge-laser, kuncishiswa ingozi yokulimala kwamadayimane kanye nethuba eliphansi lokulimala komqhubi, okuqinisekisa ukunqunywa kwekhwalithi ephezulu kanye nezimo zokusebenza eziphephile.
I-DPSS Nd: Isicelo se-YAG Laser ekusikeni kweDayimane
I-laser ye-DPSS (Diode-Pumped Solid-State) Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) ekhiqiza ukukhanya okuluhlaza okuphindwe kabili okungu-532 nm isebenza ngenqubo eyinkimbinkimbi ehilela izingxenye eziningana ezibalulekile kanye nezimiso zomzimba.

- I-laser ye-Nd:YAG enesembozo esivulekile esibonisa ukukhanya okuluhlaza okuphindwe kabili okungu-532 nm
Isimiso Sokusebenza se-DPSS Laser
1. Ukupompa kwe-Diode:
Inqubo iqala nge-laser diode, ekhipha ukukhanya kwe-infrared. Lokhu kukhanya kusetshenziselwa "ukupompa" ikristalu ye-Nd:YAG, okusho ukuthi kuvusa ama-ion e-neodymium afakwe ku-yttrium aluminium garnet crystal lattice. I-laser diode ihlelwe ku-wavelength ehambisana ne-spectrum yokumunca kwama-ion e-Nd, okuqinisekisa ukudluliswa kwamandla okuphumelelayo.
2. Ikristalu le-Nd:YAG:
Ikristalu ye-Nd:YAG iyindlela yokwandisa amandla esebenzayo. Lapho ama-ion e-neodymium evuselelwa ukukhanya okupompayo, amunca amandla bese ethuthela esimweni samandla aphezulu. Ngemva kwesikhathi esifushane, lawa ma-ion abuyela esimweni samandla aphansi, akhulule amandla awo agciniwe ngesimo sama-photon. Le nqubo ibizwa ngokuthi ukukhishwa okuzenzakalelayo.

3. Ukuguqulwa Kwenani Labantu kanye Nokukhishwa Okushukunyiswayo:
Ukuze kwenzeke isenzo se-laser, kumele kufezwe ukuguqulwa kwenani labantu, lapho ama-ion amaningi esesimweni sokujabula kunasesimweni samandla aphansi. Njengoba ama-photon egxuma phakathi kwezibuko zesikhala se-laser, avuselela ama-ion e-Nd ajabule ukuthi akhiphe ama-photon amaningi esigaba esifanayo, isiqondiso, kanye nobude be-wavelength. Le nqubo yaziwa ngokuthi ukukhishwa okushukunyisiwe, futhi yandisa ukuqina kokukhanya ngaphakathi kwekristalu.
4. Umgodi we-Laser:
Isikhala se-laser ngokuvamile sinezibuko ezimbili kunoma iyiphi ingxenye yekristalu ye-Nd:YAG. Esinye isibuko sikhanya kakhulu, kanti esinye sikhanya kancane, okuvumela ukukhanya okuthile ukuba kuphume njengoba i-laser ikhipha. Isikhala sihambisana nokukhanya, sikukhulisa ngokusebenzisa imijikelezo ephindaphindwayo yokukhishwa okushukunyisiwe.
5. Ukuphindaphinda Kabili (Isizukulwane Sesibili Se-Harmonic):
Ukuze kuguqulwe ukukhanya kwemvamisa okuyisisekelo (ngokuvamile okungu-1064 nm okukhishwa yi-Nd:YAG) kube ukukhanya okuluhlaza (532 nm), ikristalu ephindwe kabili (njenge-KTP - Potassium Titanyl Phosphate) ifakwa endleleni ye-laser. Le kristalu inesici sokubona esingeyona i-linear esivumela ukuthi ithathe ama-photon amabili okukhanya kwe-infrared kokuqala bese iwahlanganisa abe yi-photon eyodwa enamandla aphindwe kabili, ngakho-ke, ingxenye yobude bokukhanya kokuqala. Le nqubo yaziwa ngokuthi isizukulwane sesibili se-harmonic (SHG).
6. Umphumela Wokukhanya Okuluhlaza:
Umphumela walokhu kuphinda kabili kwemvamisa ukukhishwa kokukhanya okuluhlaza okotshani okukhanyayo ku-532 nm. Lokhu kukhanya okuluhlaza kungasetshenziselwa izinhlelo zokusebenza ezahlukahlukene, kufaka phakathi ama-laser pointers, imibukiso ye-laser, i-fluorescence excitation kuma-microscopy, kanye nezinqubo zezokwelapha.
Lonke lolu hlelo lusebenza kahle kakhulu futhi luvumela ukukhiqizwa kokukhanya okuluhlaza okunamandla aphezulu, okuhlangene ngendlela ehlelekile nethembekile. Isihluthulelo sempumelelo ye-laser ye-DPSS ukuhlanganiswa kwe-solid-state gain media (Nd:YAG crystal), ukupompa kwe-diode okusebenzayo, kanye nokuphindaphindwa kwemvamisa okuphumelelayo ukuze kufezwe ubude bokukhanya obufiselekayo.
