The
laser
output
can
be
either
a
continuous
wave
(CW),
xed-amplitude
signal,
a
modulated
signal,
or
a
signal
with
increased
linewidth
(coherence
control).
Attenuator
If
you
have
the

there
are
two
power
modes
for
both
the
xed-amplitude

the
modulated,
and
the
increased

signals
.
Y
ou
can
either
specify
the

power
(P

or
specify
the
laser
power
and
the
attenuation
(Attenuation
