    • If the wave is spatially localized, the linear Landau damping is properly done by Fourier transform where the wavenumber dependence of the damping can be accounted for. Such a spatial localization may have an important effect on the Langmuir wave damping as discussed recently by A. Simon and R. Short, Bull. Am. Phys. Soc. 42, 1882 (1997).

    • Other shapes such as Gaussians, a finite sum of sinusoids such as given by Eq. (34) in Sec. III b but with constant phases, or the (diffraction-limited) field at the focus of a cylindrical lens. An advantage of 33 over a Gausian is that the lateral dimensions for a Gaussian must be quite large to avoid short wavelength noise arising from not adequately resolved transverse wavelengths. We did not experiment with other shapes but expect similar results with the proper normalizations.

    • The strong damping limit is appropriate (in a homogeneous plasma at least) provided the absolute threshold is not exceeded. Near the focus, the absolute intensity is exceeded for SRS and a steady-state spatial gain rate will be restored only by pump depletion or gradient stabilization.
