Ntau zaus hopping 589 nm fiber ntau zaus ob npaug laser
Cov khoom piav qhia
Kev nrawm nrawm nrawm Raman fiber ntau ib zaug dhau ob zaug laser (RFA-SSHG JF) tau tsim los ntawm pab pawg Erbium kom tau raws li qhov xav tau ntawm sodium lidar rau zaus hloov pauv ntawm 589 nm laser.Txais siv ultra-nqaim linewidth ECDL raws li cov noob qhov chaw, Siv kev kub ceev modulator rau zaus hopping, siv tag nrho-fiber Raman amplifier los pab txhawb lub zog laser thiab ib zaug dhau ib ntus polarization siv lead ua, Erbium pawg tau txais lub zog siab zaus ob npaug laser nrog zaus hopping.Cov khoom no tuaj yeem ua tiav ob 589 nm laser outputs.Ib qho yog siv los xauv lub laser mus rau sodium atomic absorption kab ntawm qhov zaus.Lwm lub laser txhawb f + 630MHz, F + 0 MHz, F-630mhz ceev hloov.Lub zog laser tuaj yeem ncav cuag ntau dua 1.8 W, uas zoo kawg nkaus phim qhov kev thov ntawm sodium lidar noob qhov chaw.
