I-Dpss Laser ivelisa njani i-532nm green laser?
Ukuveliswa kokukhanya kwelaser eluhlaza kwe-532nm ngetekhnoloji yelaser ye-DPSS (Diode-Pumped Solid State) kubandakanya inkqubo entsonkothileyo. Ekuqaleni, ukukhanya kwe-infrared kwi-1064 nm kuveliswa kusetyenziswa ikristale efakwe i-neodymium epompelwe yiDiode Laser. Olu kukhanya emva koko luqondiswa ngekristale engeyomgca, ephinda kabini imvamisa yayo, inciphise ngempumelelo ubude bayo be-wavelength, ngaloo ndlela ivelisa ukukhanya kwelaser eluhlaza okuqaqambileyo kwi-532 nm.

Izicelo eziqhelekileyo zeLaser eluhlaza ezingama-525nm
Ukuphonononga umhlaba we-525nm green laser, ingakumbi iintlobo zayo ezidityaniswe nefayibha, kubonisa ukubaluleka kwayo ekuphuhliseni ii-laser dazzlers. Ezi zixhobo ezingezizo ezibulalayo zenzelwe ukuphazamisa okanye ukuphazamisa umbono wethagethi okwethutyana ngaphandle kokubangela umonakalo ohlala ixesha elide, nto leyo ezenza zibe lukhetho olubalaseleyo kwizicelo zomkhosi nezomthetho. Zisetyenziswa kakhulu ekulawuleni izihlwele, ukhuseleko lweendawo zokuhlola, kunye nokuthintela izoyikiso ezinokubakho, ii-laser dazzlers zinciphisa umngcipheko wokwenzakala ixesha elide. Ngaphezu koko, ukusetyenziswa kwazo kwiinkqubo zokulwa nezithuthi kubonisa amandla azo okumisa okanye ukulawula izithuthi ngokukhuselekileyo ngokuzifihla okwethutyana abaqhubi, ukuqinisekisa ukhuseleko ngexesha lokulandela okanye kwiindawo zokuhlola.
Ukusetyenziswa kwee-laser eziluhlaza ze-525nm kudlulela ngaphaya kwezicelo zobuchule ukuya kubandakanywa nokuphucula ukukhanya kunye nokubonakala. Ukukhetha ubude be-525nm, kufutshane nobukhali beliso lomntu phantsi kweemeko ezininzi zokukhanya, kunika ukubonakala okugqwesileyo. Olu phawu lwenza i-laser eluhlaza ye-525nm ibe sisixhobo esibalulekileyo sokukhanyisa, ngakumbi kwimisebenzi yokukhangela nokuhlangula apho ukubonakala kubaluleke khona. Ngaphezu koko, ukubonakala kwazo okuphezulu kuzenza zilungele imisebenzi yangaphandle efana nokuhamba intaba, ukukhempisha, kunye nokubonisana ngexesha likaxakeka, zisebenza njengesibane esinamandla kwiimeko ezinzima.
Iniimeko zokuzikhusela, ukuchaneka nokubonakala kwee-laser eziluhlaza ze-525nm zisetyenziselwa ukuchaza iithagethi kunye nokufumana uluhlu, zinceda ekulinganisweni ngokuchanekileyo komgama ukuya kwiithagethi nasekukhokeleni izixhobo zomkhosi, ngaloo ndlela zongeza ukusebenza kakuhle kwemisebenzi yomkhosi.
