Stop RIGHT there. A laser does NOT have this property.

You'll need some sort of ridiculously complex spotlight for your application.

Actually there is a device that can do just that. It called a flat top beam shaper. From just a cursory glance I don't think it will be useful at the distances this person wants

to Cyparagon>

Personally I tried couple of inch sized laser illuminator which gave 10m circle spot at 100m with pretty uniform intensity inside (only weird thing that at edge of spot was some concentric high-dense circular lines - Fresnel lens???). It really exists! It seemed it has not complex optical system (only 1 inch long).Anyway I do not want any bulky one.
Then I am convinced that it is feasible to get uniform circle spot from diverged beam.

Any other idea? (recommended laser diodes etc.)

Guys any advice about some proper combination of laser diode with small-size optics (actually where to start) for some decent uniform 100mrad beam?
