I am doing some testing right now, but it definitely feels like, increasing Laser Turret Min Range would be much better and making its cone more narrow. Right now my walls seem to be dying more to them than nuclear biters.
Probably there is a reason why it is like this right now, would be nice to know.

Yes, perhaps this turret should be given similar changes as the shotgun turret
I can't say yet when the next release will be, but I think I will include this change in it.

OK So i did a bit for modification as promised.

Here you can see original with 13 min radius and 0.35 turret Rotation
I did one with 20 min radius and 0.2 rotation. This seems much better to use for defence, it fixes weird dead zone issue and demolishing wall (at least for me) Technically this could be considered nerf, because now it covers less space.
I have not touched Max range, that would be considered too much of a change for this and messing with balance much more
