Blinking indicates that the laser module is not yet stable and the
optical output power is undefined. This happens e.g. after change of
tuning parameters and might take some seconds.
•
Dark green indicates that the optical output is off.
•
Bright green indicates that the laser module has finished its tuning
and the optical output is on.

in THz.
