The special dual wavelength narrow linewidth laser system of our
company in the top view can provide two kinds of wavelength narrow
linewidth fiber coupling output. The laser adopts the core
technologies such as wavelength locking of body Bragg grating
(VBG), directional optical feedback and built-in semiconductor
refrigeration module to realize the narrow linewidth, stable power
and stable spectral output of the system.(Download PDF)
