Endikimbeni eguquguqukayo yentuthuko yezobuchwepheshe besimanje, ama-laser akha indawo eyingqayizivele, ehlukaniswa ngokunemba kwawo okungenakuqhathaniswa, ukuzivumelanisa nezimo, kanye nobubanzi bokusetshenziswa kwawo. Ngaphakathi kwalesi sigaba, i-laser eluhlaza engu-525nm, ikakhulukazi ngesimo sayo esihlanganisiwe ngefayibha, ivelele ngombala wayo oyingqayizivele kanye nokusebenza okubanzi ezindaweni ezisukela ezindleleni ezingezona ezibulalayo kuya ekungeneleleni kwezokwelapha okuyinkimbinkimbi. Lokhu kuhlola kuhlose ukuveza izinhlelo zokusebenza ezahlukahlukene zeAma-laser aluhlaza angu-525nm, eqokomisa indima yabo ebalulekile emikhakheni ehlukahlukene efana nokuphoqelelwa komthetho, ukunakekelwa kwempilo, ukuzivikela, kanye nemisebenzi yangaphandle yokuzijabulisa. Ngaphezu kwalokho, le nkulumo izocacisa umehluko phakathi kwama-laser aluhlaza angama-525nm nama-532nm, igcizelela izindawo zabo ezibusayo.
Izicelo ze-532nm Green Laser
Ama-laser aluhlaza angu-532nm adumile ngombala wawo oluhlaza okhanyayo, ocacile, ohambisana kakhulu nokuzwela okuphezulu kweso lomuntu ngaphansi kwezimo zokukhanya ezivamile, okwenza abe usizo kakhulu ezindaweni eziningi. Emkhakheni wokuhlola kwesayensi, lawa ma-laser abalulekile kwi-microscopy ye-fluorescence, enza kube lula ukuvusa ama-fluorophores amaningi, kanye ne-spectroscopy ukuze kuhlaziywe ngokuningiliziwe ukwakheka kwezinto. Umkhakha wezokwelapha usebenzisa lawa ma-laser ezinqubweni ezifana ne-ophthalmologic laser photocoagulation yokwelapha ukuhlukaniswa kwe-retinal, kanye nezicelo zesikhumba ezihlose ukususa izilonda ezithile zesikhumba. Ukusetshenziswa kwezimboni kwama-laser angu-532nm kubonakala emisebenzini edinga ukubonakala okuphezulu njengokuqopha, ukusika, kanye nokuqondanisa kwe-laser. Ngaphezu kwalokho, ukukhanga kwawo kuma-electronics abathengi be-laser pointers, kanye nasembonini yezokuzijabulisa yemibukiso yokukhanya, kugcizelela ukusebenza kwawo okubanzi, ngenxa yemisebe yawo eluhlaza emangalisayo.
I-Dpss Laser ikhiqiza kanjani i-532nm green laser?
Ukukhiqizwa kokukhanya kwe-laser eluhlaza okungu-532nm ngobuchwepheshe be-laser be-DPSS (Diode-Pumped Solid State) kuhilela inqubo eyinkimbinkimbi. Ekuqaleni, ukukhanya kwe-infrared okungu-1064 nm kukhiqizwa kusetshenziswa ikristalu elifakwe i-neodymium eliphampa yi-Diode Laser. Lokhu kukhanya kube sekuqondiswa ngekristalu engeyona i-linear, ephinda kabili imvamisa yayo, inciphise ngempumelelo ubude bayo be-wavelength, ngaleyo ndlela ikhiqize ukukhanya kwe-laser eluhlaza okugqamile okungu-532 nm.

Izicelo Ezijwayelekile Ze-Laser Eluhlaza Okwe-525nm
Ukucwila endaweni ye-laser eluhlaza engu-525nm, ikakhulukazi izinhlobo zayo ezihlanganiswe ngefayibha, kwembula ukubaluleka kwayo ekuthuthukiseni ama-laser dazzlers. Lezi zikhali ezingezona ezibulalayo zenzelwe ukuphazamisa okwesikhashana noma ukuphazamisa umbono womuntu ohlosiwe ngaphandle kokulimaza isikhathi eside, okwenza zibe ukukhetha okuyisibonelo kwezicelo zempi kanye nezokugcina umthetho. Zisetshenziswa kakhulu ekulawuleni izixuku, ukuphepha kwezindawo zokuhlola, kanye nokuvimbela izinsongo ezingaba khona, ama-laser dazzlers anciphisa ingozi yokulimala kwesikhathi eside. Ngaphezu kwalokho, ukusetshenziswa kwawo ezinhlelweni zokulwa nezimoto kubonisa ikhono lawo lokumisa noma ukulawula izimoto ngokuphepha ngokuphambukisa abashayeli okwesikhashana, ukuqinisekisa ukuphepha ngesikhathi sokulandela noma ezindaweni zokuhlola.
Ukusetshenziswa kwama-laser aluhlaza angu-525nm kudlulela ngale kwezinhlelo zokusebenza zamaqhinga kufaka phakathi ukukhanya nokuthuthukiswa kokubonakala. Ukukhetha ubude be-wavelength obungu-525nm, obuseduze nokuzwela okuphezulu kweso lomuntu ngaphansi kwezimo eziningi zokukhanya, kunikeza ukubonakala okumangalisayo. Lesi sici senza i-laser eluhlaza engu-525nm ibe ithuluzi elibalulekile lokukhanyisa, ikakhulukazi emisebenzini yokusesha nokutakula lapho ukubonakala kubalulekile khona. Ngaphezu kwalokho, ukubonakala kwazo okuphezulu kuzenza zilungele imisebenzi yangaphandle njengokuhamba ngezinyawo, ukukhempa, kanye nokubonisa izimpawu eziphuthumayo, okusebenza njengesibani esinamandla ezimweni ezimbi kakhulu.
Inizimo zokuzivikela, ukunemba nokubonakala kwama-laser aluhlaza angu-525nm kusetshenziselwa ukuqokwa kwezinjongo kanye nokuthola ibanga, kusiza ekulinganisweni okunembile kwamabanga ukuya ezinhlosweni nasekuqondiseni izikhali, ngaleyo ndlela kwandisa ukusebenza kahle kwemisebenzi yezempi. Zidlala indima ebalulekile ekuqapheni nasekuhloleni, ikakhulukazi ngesikhathi sokusebenza ebusuku, ngokukhanyisa nokumaka izinjongo zamakhamera okuqapha kanye namadivayisi okubona ebusuku.
Iinsimu yezokwelaphaIphinde izuze ekuthuthukisweni kobuchwepheshe be-laser eluhlaza obungu-525nm, ikakhulukazi ekufakweni kwe-retinal photocoagulation, okugcizelela amandla ayo okuguqula izici ezahlukene zokwelashwa. Ngaphezu kwalokho, ukuthuthukiswa kwama-laser anamandla amakhulu okusetshenziswa kwezimboni nezesayensi kubonisa ukuguquguquka kanye namandla ama-laser aluhlaza, kanye nentuthuko efana nama-diode e-laser aluhlaza asekelwe ku-AlInGaN athola imiphumela engu-1W ku-525nm, okubonisa amathuba amasha ocwaningo kanye nentuthuko.
Ukucabangela imithetho kanye nezinqubo zokuphepha ezilawula ukusetshenziswa kwama-laser aluhlaza angama-525nm kubalulekile, ikakhulukazi uma kubhekwa ukusetshenziswa kwawo ekuvimbeleni okungeyingozi kanye nokuphepha komphakathi, ukuqinisekisa ukuthi izinzuzo zobuchwepheshe be-laser eluhlaza zisetshenziswa ngendlela efanele, kunciphisa izingozi ezihlobene nokusetshenziswa kabi noma ukuchayeka ngokweqile.
Ekuphetheni, i-laser eluhlaza engu-525nm ivela njengesibani sokuqamba izinto ezintsha, kanye nokusetshenziswa kwayo okuhlanganisa ukuphepha, ukwelashwa kwezokwelapha, ucwaningo lwesayensi, nokunye. Ukuzivumelanisa nezimo kwayo kanye nokusebenza kahle, okusekelwe ezicini ezingokwemvelo zobude be-wavelength eluhlaza, kubonisa amandla e-laser okuqhuba intuthuko kanye nokusungula izinto ezintsha emikhakheni eminingi.
