Light Beam in simulation

  I have a Gaussian spectral distribution light beam with a mean wavelength of nm with a Half width of Gaussian of 5nm of 100W Emittance power. When entering this characteristics to the optics software I'm looking how to convert this 5nm FWHM to a angle as shown in figure below. Does anyone know how to find this AWHM angle in the Ansys software.

  There have been few typo in the question. Below is the light beam characteristics and Im looking what is the FWHM angle or is the above figure in the problem is correct? IS there a way to find this FWHM angle?nSpectrum Distribution = GaussiannMean Wavelength 425nmnHalf Width of Gaussian=5nmnEmitted Power=100WnAir area(r=1mm) =3.14mm2nlight beam in perpendicular to the surfacen
