I've used laser pointers with rangefinders for focusing and they work well.
Surprisingly you can also use them with SLR's. If you have a micro prism part
in the focusing screen you will get a pattern of dots which will converge when
you have focus. Aiming accurately enough to use a split image screen is
difficult, but I have succeeded using a Rollei TLR where the screen is large
enough for accurate aim.
All the best
