EnvGrid(zmax, referenceλ, λ_lims, trange; δt=1, thg=false)

Time grid for simulations with envelope (a.k.a. analytic) fields

Arguments

• zmax::Real : Total distance to propagate
• referenceλ::Real : Reference wavelength (e.g. centre wavelength of input pulse)
• λ_lims::Tuple{Real, Real} : Wavelength limits of the frequency window
• trange::Real : Total extent of the time window required
• δt::Real : Sample spacing in time. The value actually used is either δt or the value required to satisfy trange and λ_lims, whichever is smaller.
• thg::Bool : Whether the grid should include space for the third hamonic (default: false)

FreeGrid(Rx, Nx, Ry, Ny; window_factor=0.1)

Spatial grid for full 3D freespace propagation with x/y half-width Rx/Ry and Nx/Ny samples. window_factor determines by how much the grid size is extended to fit a filtering window.

RealGrid(zmax, referenceλ, λ_lims, trange; δt=1)

Time grid for simulations with real-valued (field-resolved) fields

Arguments

• zmax::Real : Total distance to propagate
• referenceλ::Real : Reference wavelength (e.g. centre wavelength of input pulse)
• λ_lims::Tuple{Real, Real} : Wavelength limits of the frequency window
• trange::Real : Total extent of the time window required
• δt::Real : Sample spacing in time. The value actually used is either δt or the value required to satisfy trange and λ_lims, whichever is smaller.
