5.1.2 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 section 2.3. The
selection file makes the spectral amplitude de-
fined by the text file amp.txt (see subsection 5.4.1
for format description) which resides in the default
directory C:\dazzler\data (see section 5.3.1).
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 subsection 5.4.1 for for-
mat description) residing in the default directory
C:\dazzler\data (see section 5.3.1).
When both is selected, the resulting spectral phase is the sum of the polynomial result and the
file result. The formulas are described in section 2.3.
When the SelfC (Self Compensation) button is pressed, the order2, order3 and order4 controls
are filled with the negated coefficients of the dispersion introduced by the crystal in ordinary
