Waist

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

This parameter sets the width where the amplitude of the beam in the transverse direction has decayed to \frac{1}{e} in the focal plane. The tensorial nature of the beam allows for different Waist sizes in \hat{s} and \hat{p} direction. If only one waist is specified, it is used for both directions. The beam waists are specified in units of meter, \units{m}.
