390nm nqaim linewidth zaus ob npaug ntawm fiber ntau laser

Qauv:

Lus piav qhia luv luv:

Erbium pab pawg tsim cov nqaim, tsis yog hom hopping, siab zog 390 nm laser series (EFA-FHG-390).EFA-FHG-390 series siv 1560 nm fiber ntau DFB laser nrog kHz linewidth ua cov noob qhov chaw.All-fiber amplifier amplifies lub zog laser.390nm laser yog tau los ntawm ntau zaus ob npaug ntawm lub sij hawm polarization siv lead ua thiab zaus hloov cov tswv yim ntawm cascade resonant zaus ob npaug.Piv nrog rau cov diode lasers, EFA-FHG-390 series muaj cov yam ntxwv ntawm nqaim laser linewidth (Lorentz kab dav <50 kHz), tsis muaj hom dhia nyob rau hauv ib tug loj ntau yam ntawm kub thiab vibration tej yam kev mob, zoo laser beam zoo (M² <1.3). ), thiab loj tso zis zog.
