Generally spoken, it is best to have a divergence as small as possible.
The beam divergence is in direct relation to the beam size at aperture: By increasing the beam size at the aperture it is possible to reduce the divergence - and vice versa. This is possible to a certain extent, depending on the technology.
To see the importance of the beam divergence, please make some example calculations with our divergence calculator - you can clearly see the importance if the distance is increased:
