If I can weigh in, I've got a class IV 520nm diode (multimode) with a 3E lens and all of my 532nm lasers have better divergence. My 520nm diode's divergence isn't that great at all, I haven't measured it but it's probably right around the same as my 3W 445nm Sanwu laser
Thank you both for clearing that up for me.
I forgot to mention that I recently moved to the high desert (Reno nevada) so it gets pretty cold here.
Perhaps a diode would withstand the cold better than a DPSS..
