Make that "factor", not function. Could be interesting, but we'd need a lot of distance between the laser operator and the person with the ruler. Also, a spot size small enough to measure directly would probably mean a hazardously bright environment directly in the beam. Kurt, you've researched lasers over relatively short distances, what do you think about this? --- Chuck Hards <chuckhards@yahoo.com> wrote:
Don't you think that coherence will be a contributing function to brightness?

Seems like beam coherence (spread over distance) might also be a good thing to measure. That's the only thing that might require some space.
