Erbium Glass Micro laser
Tlhaloso ea Sehlahisoa
1535nm Ultra-small erbium glass eye-safe solid-state laser e sebelisoa bakeng sa laser ho tloha, 'me 1535nm wavelength e boemong ba leihlo la motho le fensetere ea sepakapaka, ka hona e fumane tlhokomelo e kholo mafapheng a laser ho qala. le puisano ea elektronike. Laser ea khalase ea Erbium bakeng sa sekhahla sa ho pheta-pheta ha sekhahla se tlase (tlase ho 10hz) ho fumana mofuta oa laser. Li-laser tsa rona tse sirelelitseng mahlo li 'nile tsa sebelisoa ho li-rangefinders tse nang le mefuta e mengata ea 3-5km le botsitso bo phahameng bakeng sa ho shebisisa lithunya le li-pods tsa drone.
Ha ho bapisoa le li-laser tse tloaelehileng tsa Raman le OPO (Optical Parametric Oscillation) lasers tse hlahisang maqhubu a sireletsehileng a mahlo, li-laser tsa khalase ke lintho tse sebetsang tse hlahisang maqhubu a sireletsehileng a mahlo ka kotloloho, 'me li na le melemo ea sebopeho se bonolo, boleng bo botle ba libalaka, le ts'epahalo e phahameng. Ke mohloli o ratoang oa leseli bakeng sa li-rangefinders tse sireletsehileng mahlong.
Li-laser tse tsoang ka bolelele ba maqhubu a malelele ho feta 1.4 um hangata li bitsoa "leihlo le bolokehileng" hobane leseli le karolong ena ea bolelele ba maqhubu le kenella ka matla cornea le lense ea leihlo, kahoo ha le khone ho fihla retina e hlokolosi haholoanyane. Ho hlakile hore boleng ba "tšireletseho ea mahlo" ha bo itšetlehe feela ka bophahamo ba maqhubu, empa hape bo itšetlehile ka boemo ba matla le matla a khanyang a ka fihlang leihlo. Li-laser tse sireletsang mahlo li bohlokoa ka ho khetheha ho 1535nm laser rangeng le radar, moo leseli le hlokang ho tsamaea sebaka se selelele ho ea kantle. Mehlala e kenyelletsa li-laser rangefinders le li-free-space optical communications.
