DeltaK

Type:Vector<float>
Range:[v_1, …, v_2]
Default:-/-
Appearance:optional

Sets the sampling spacing in \pvec{k}-space for the spectrum of the beam. The default value is determined from the extent of the beams intensity profile in transverse direction. For a Gaussian beam profile it defaults to

\begin{eqnarray*}
\Delta k = \frac{\pi}{\sqrt {-\log( 10^{-12} ) } W},
\end{eqnarray*}

where W is the Waist parameter of the beam.
