Primary vendor documentation titled \i[Plane wave and beam source - Simulation object]. Frequency/Wavelength tab, Standard source: PULSELENGTH explicitly means full width at half maximum of the temporal power profile. No personal byline or publication date is asserted.
The standard-source PULSELENGTH setting is the temporal power FWHM. “Manual calculation of the source time signal” gives a sinusoidal carrier multiplied by a Gaussian field envelope and distinguishes the pulse length from the envelope parameter.
