finesse.utilities.homs.HG_to_LG(n, m)

Returns the coefficients and mode indices of the Laguerre-Gaussian modes required to create a particular Hermote-Gaussian mode.

Parameters

n, m: integer

Indices of the HG mode to re-create.

Returns

coeffcients: array_like

Complex coefficients for each order=n+m LG mode required to re-create HG_n,m.

ps, ls: array_like

LG mode indices corresponding to coefficients.
