Hi , i'm a newbie in this laser world , and i would like to get some advice of any expert that can help us to find a good combination of a laser and a beamexpander. For a scientific experiment we are looking for a laser and expander to create a strong beam with very little divergence .The beam spot has to be visible for about 6 miles or more with lowest divergence possible , hopefully about 0,1 mrad or a bit more. Any advice will be welcome !:thanks:
