Orange area: spectral amplitude control
The spectral amplitude is programmed either by a
text file or by the dials of the orange area, or a com-
bination thereof. When the Amplitude selector is
set to
dials
, the spectral amplitude is defined by
the controls of the orange area. The principle of
this shaping is to combine a supergaussian spectral
shape with an optional hole at a given position: the
exact formulas are described in
. The
selection
file
makes the spectral amplitude de-
fined by the text file
amp.txt
(see
for format description) which resides in the default
directory
C:\dazzler\data
(see section
).
The selection
both
programs an amplitude which
is the product of the dials result and the file result.
5.1.3
Green Area: spectral phase control
The spectral phase selector is similar to the am-
plitude selector control. When
polynomial
is se-
lected, the dials program a polynomial phase func-
tion with respect to the specified central wave-
length. This central wavelength is automatically
following the center position of the amplitude
shape when the ”auto” box is checked. It can be
set arbitrarily if auto is unchecked.
The
file
selection generates a spectral phase from
the file
phase.txt
(see
for for-
mat description) residing in the default directory
C:\dazzler\data
(see section
When
both
is selected, the resulting spectral phase is the sum of the polynomial result and the
file result. The formulas are described in
When the SelfC (Self Compensation) button is pressed, the
