finesse.utilities.wigner.gauss_norm(n, q, lam=1.064e-06, include_gouy=True)[source]¶

The normalization factor for a 1D HG electric field distribution to ensure that the overlap integral equates to 1.

Traditionally the normalization includes a Gouy phase factor for free space propagation but that can be turned off by setting include_gouy=False
