What is a good divergence?

just recently i found an online divergence calculator and i decided it would be cool to measure its divergence :)
so after the setup i found that my basic green laser has a divergence of exactly 1.2303143398648593 mRad, or more simply 1.2 mRad :P
so is this a good divergence? if not, what is?
Edit: oh hey look, 30th post :D

That's a fairly reasonable divergence IMO, but 'good' is subjective. Someone else might think that isn't good divergence, they might think 0.5mRad is good.
 
I would consider the standard for "good" would be most single modes. In general 532nm have good divergence too. I suppose if you don't need a 3 element lens for correction you are in the good range.
 
My 473nm Pl-E Pro gave me a divergence measurement of 0.5mRad, which is the lowest I've ever had. I'd consider 1.2mRad and less to be good.
