Well, with the correct set of optics, most anything is possible. You could get a 1 watt ls to form a laser like beam, though the loss would be increadible. To do this is simple in concept, but troublesome to build. First off, the smaller the beam, the smaller the source has to be. Simplest way would be to put a pin hole aperature in front of the ls. Now that you have a 1mm source and have lost 95-99% of the total luminous output, simply use a thick plano convex with the round side toward the aperature to get the light to come to a point focus and place two more plano convex after. 1 to paralell out the light at the correct diameter and the second is optional to tighten up the focus. The second lens, if slidable, would allow you to set the convergance to a given distance to keep the spot as tight as possible.
This is the system High End Systems used in thier laser emulator. It was a light for clubs that wanted the look of lasers without the hassle of permits. It used a 1200watt arc lamp to throw a beam off of two digitally controlled mirrors on high speed stepper motors. It allowed for a spot about 3-5" in diameter at 100'to move fast enough to shape out a letter. If you had one unit for each letter you could spell out the name of the club.
