If it was mounted on the tip of a 15cm pole (for example) could you combine a large gear movement at the far end, with a smaller movement (or even a pivot point) near the laser, to produce scans of a Very Small Area?

A lathe and a milling machine (CNC controlled of course) to create clay moulds. Bake in a kiln (or home oven), then pour your thermoplastic in. Once you have the hang of soft plastic, try moving up to brass. Your next assignment: a working steam engine, driving a hand-wound alternator. Ooh!

There's a video that, if nothing else, is a fairly good demo of the tech: http://revision3.com/systm/laserscan/ On a similar note David 3D Scanner ( http://www.david-laserscanner.com/ ) allows you to make 3D scans of objects using a laser line level and a webcam.
