Ok first off I know that this does not qualify as a "laser", and that sunlight diverges. However, if perhaps the small lens that focused the sunlight into a approximate beam was exactly right I would imagine that if this thing was big enough it would be pretty powerful. A glass lens 2 feet in diameter would be hard to find and expensive, but maybe a Fresnel lens would work. The smaller concave lens would have to be glass.
