Determine wavelength for a given index of refraction corresponding to the group velocity.

The estimate of the wavelength is made by successive linear extrapolations. The procedure starts from the given wavelength and terminates if the index of refraction is equal to the target value within the given precision.

Parameters

wstart value wavelength [nm]
epsprecision index of refraction
Returns
return value wavelength [nm]
