I'm passing light from a single light source through a gap that really
isn't narrow but I'm getting a diffraction grating effect (light and dark
striations) - which I don't want. Is there some settings in the ambient,
diffuse, etc. that would reduce/elliminate this effect?

You are not getting a diffraction effect, it is something else. Put
simply, diffraction is a very complex effect to simulate, POV does not
even try.
My best guess is that you are somehow getting a coincident surface
effect, or are doing something else that causes precision errors. I
can't say more without more details.

Is this an area light? If so, you'll need to increase its resolution.
Probably by a lot.

I have noticed that adding jitter to an area light, with anti-aliasing,
will do just as much smoothing as increasing the number of lights in
the area light.

Please note that this is the wrong group for your question. Please read the
messages in the povray.announce.frequently-asked-questions group, in
particular the "Welcome To The POV-Ray News Groups" message. Your question
would fit in povray.newusers.
