I was looking for something like these for another kind fo project but I think they will be useful for laser projectors as well. Individual samples are pretty cheap.
First is the electrically tunable lense.

Can be used to control divergence when needed.
Beam steering dual axis mirror:

While not as fast as fast as a galvo I think it is fast enough to add as a third mirror to increase the scanning angle of your projector. Like a moving head laser projector but without the bulky moving parts and motors. Thoughts?
They have even made a despeckler for lasers.

While I like the speckle effects some people seem to complain about it.
So has anyone here tried any of these products?
I'm going to get the lens to add a very fast autofocus to a small video projectors but I can run some other tests on it with lasers if anyone has any requests...
