DispersiveCavity.get_alpha(psi, time=None)[source]#

Return the intracavity field

Parameters:

psi (torch.tensor) – The wave function of the gas
time (float, optional) – The time at which to compute the intracavity field. Defaults to None.

Returns:

The intracavity field \(\alpha\)

Return type:

float
