Bhalisela Imidiya Yethu Yezokuxhumana Ukuze Uthumele Ngokushesha
Kundwangu eguquguqukayo yentuthuko yesimanje yezobuchwepheshe, ama-lasers akha i-niche eyingqayizivele, ehlukaniswa ngokunemba kwawo okungenakuqhathaniswa, ukuguquguquka, kanye nobubanzi obuphelele bokusebenza kwawo. Ngaphakathi kwalo mbuso, i-laser eluhlaza engu-525nm, ikakhulukazi ngendlela yayo ehlanganiswe nefayibha, igqama ngombala wayo oyingqayizivele kanye nokusebenza okubanzi ezindaweni ezisukela ezindleleni zokuvimbela ezingabulali kuye ekungeneleleni kwezokwelapha okuyinkimbinkimbi. Lokhu kuhlola kuhlose ukuqaqa izinhlelo zokusebenza ezihlukene ze525nm ama-laser aluhlaza, egqamisa indima yabo ebalulekile emikhakheni eyahlukene efana nokugcinwa komthetho, ukunakekelwa kwezempilo, ezokuvikela, nezokungcebeleka zangaphandle. Ukwengeza, le nkulumo izocacisa umehluko phakathi kwe-525nm kanye nama-laser aluhlaza angama-532nm, igcizelela izindawo zabo zokubusa.
532nm Green Laser Izicelo
Amalaser aluhlaza angu-532nm agujwa ngombala wawo okhanyayo, ogqamile oluhlaza, oqondaniswe eduze nokuzwela okuphezulu kweso lomuntu ngaphansi kwezimo zokukhanya ezivamile, okuwenza abe yigugu ezizindeni eziningi. Emkhakheni wokuhlola kwesayensi, lawa ma-lasers abalulekile ku-fluorescence microscopy, enza kube lula ukuthokozela kwe-spectrum ebanzi ye-fluorophores, kanye ne-spectroscopy ukuze kuhlaziywe okuningiliziwe kokuqanjwa kwezinto ezibonakalayo. Umkhakha wezokwelapha usebenzisa lawa ma-lasers ezinqubweni ezifana ne-ophthalmologic laser photocoagulation yokwelapha i-retinal detachments, kanye nezinhlelo zesikhumba ezihloselwe ukususa izilonda ezithile zesikhumba. Ukusetshenziswa kwezimboni zamalaser angu-532nm kubonakala emisebenzini edinga ukubonakala okuphezulu njengokuqoshwa kwe-laser, ukusika, nokuqondanisa. Ngaphezu kwalokho, ukuheha kwabo ku-elekthronikhi yabathengi bezinkomba ze-laser, kanye nasembonini yokuzijabulisa yemibukiso ekhanyayo, kugcizelela ukusetshenziswa kwabo okubanzi, ngezilokotho zabo zemishayo eluhlaza.
I-Dpss Laser ikhiqiza kanjani i-laser eluhlaza engu-532nm?
Ukukhiqizwa kokukhanya kwelaser eluhlaza okungu-532nm kusetshenziswa ubuchwepheshe belaser ye-DPSS (Diode-Pumped Solid State) kubandakanya inqubo eyinkimbinkimbi. Ekuqaleni, ukukhanya kwe-infrared ku-1064 nm kukhiqizwa kusetshenziswa i-neodymium-doped crystal ephonswa yi-Diode Laser. Lokhu kukhanya kube sekuqondiswa ngekristalu engaqondile, ephindaphinda imvamisa yayo, inciphisa ngempumelelo ubude bayo begagasi, ngaleyo ndlela ikhiqize ukukhanya kwe-laser okuluhlaza okugqamile ku-532 nm.

525nm Green Laser Izicelo Ezivamile
Ukungena endaweni ye-laser eluhlaza engu-525nm, ikakhulukazi okuhlukile kwayo okuhlanganiswe ne-fiber, kuveza ukubaluleka kwayo ekuthuthukiseni ama-laser dazzler. Lezi zikhali ezingabulali zenzelwe ukuphazamisa okwesikhashana noma ukuphambanisa umbono walowo okuqondiwe ngaphandle kokudala umonakalo ongapheli, okuzenza zibe ukukhetha okuyisibonelo kwezempi kanye nezicelo zomthetho. Eqashwe kakhulu ukulawula isixuku, ukuphepha kwendawo yokuhlola, kanye nokuvimbela izinsongo ezingaba khona, ama-laser dazzler anciphisa ubungozi bokulimala isikhathi eside. Ngaphezu kwalokho, ukusetshenziswa kwabo ezinhlelweni ezilwa nezimoto kukhombisa amandla abo okumisa ngokuphepha noma ukulawula izimoto ngokuphuphuthekisa abashayeli okwesikhashana, ukuqinisekisa ukuphepha ngesikhathi sokujahwa noma ezindaweni zokuhlola.
Ukusetshenziswa kwama-laser aluhlaza angu-525nm kudlulela ngalé kwezinhlelo zokusebenza zamaqhinga ukuze kufakwe ukukhanya nokuthuthukisa ukubonakala. Ukukhethwa kwe-525nm wavelength, eduze nokuzwela okuphezulu kweso lomuntu ngaphansi kwezimo eziningi zokukhanya, kunikeza ukubonakala okuyingqayizivele. Lesi sici sinikeza i-laser eluhlaza engu-525nm ithuluzi eliyigugu lokukhanyisa, ikakhulukazi emisebenzini yosesho nokuhlenga lapho ukubonakala kubalulekile khona. Ngaphezu kwalokho, ukubonakala kwazo okuphezulu kuzenza zilungele imisebenzi yangaphandle efana nokuqwala izintaba, ukukhempa, nokusayina izimo eziphuthumayo, zisebenze njengesibani esinamandla ezimeni ezibucayi.
Inizimo zokuzivikela, ukunemba nokubonakala kwama-lases aluhlaza angu-525nm kusetshenziswa ukuze kuqondwe okuqondiwe kanye nokutholwa kobubanzi, okusiza esilinganisweni esinembile samabanga aya kulokho okuqondiwe kanye nezikhali eziqondisayo, ngaleyo ndlela andise ukusebenza kahle kwemisebenzi yezempi. Baphinde badlale indima ebalulekile ekuqapheni nasekuhloleni kabusha, ikakhulukazi phakathi nokusebenza ebusuku, ngokukhanyisa nokumaka okuhlosiwe kwamakhamera agadayo kanye nemishini yokubona ebusuku.
Iinsimu yezokwelaphafuthi bayazuza entuthukweni yobuchwepheshe be-laser eluhlaza engu-525nm, ikakhulukazi ku-retinal photocoagulation, egcizelela amandla abo okuguqula izici ezihlukahlukene zokwelapha. Ukwengeza, ukuthuthukiswa kwama-laser anamandla aphezulu wezinhlelo zokusebenza zezimboni nezesayensi kukhombisa ukuguquguquka namandla ama-lases aluhlaza, ngentuthuko efana ne-AlInGaN-based laser green diode efinyelela imiphumela ye-1W ku-525nm, ememezela amathuba amasha ocwaningo nentuthuko.
Ukucatshangelwa kwemithetho nezinqubo zokuphepha ezilawula ukusetshenziswa kwama-laser aluhlaza angu-525nm kubalulekile, ikakhulukazi uma kubhekwa ukusetshenziswa kwazo ekuvimbeleni okungabulali nokuphepha komphakathi, ukuqinisekisa ukuthi izinzuzo zobuchwepheshe be-laser eluhlaza zisetshenziswa ngokuzibophezela, kuncishiswe izingozi ezihlobene nokusetshenziswa kabi noma ukuchayeka ngokweqile.
Sengiphetha, i-laser eluhlaza engu-525nm ivela njengokukhanya kokuqanjwa kabusha, nezinhlelo zokusebenza zayo ezihlanganisa ukuphepha, ukwelashwa, ucwaningo lwesayensi, nokunye. Ukuvumelana nezimo nokusebenza kahle kwayo, okugxilwe ezimpahleni ezingokwemvelo ze-wavelength eluhlaza, kufanekisa amandla e-laser okuqhubekisela phambili intuthuko kanye nokuqanjwa okusha kuzo zonke izinkambu eziningi.
