First, there's no need to have both laser turrets and telescopes. You
use a telescope to aim and focus a weapons-grade laser - a two-for-one
deal.


You could do that, and it's probably a good thing to aim for, but mightn't
it be beyond their current engineering abilities for a certain cost?
Sighting telescopes don't need to be particularly large or robust, while the
military laser optics might sacrifice increased precision for larger
apertures and heat dissipation ability at low cost.

Once you've got a military beam pointer, you've got a bad-ass
telescope. You can round it out with a plethora of smaller sensor
scopes if you want - they're cheap and give redundancy.

Larger apertures automatically give increased precision - unless you
did a flubbed job grinding the lens (Hubble Space Telescope) or have
buggy software for aligning multiple mirror telescopes or adaptive
optic mirrors. These are the sorts of things that should be worked out
with the prototypes before the laser scopes begin to be mass produced
for the military by the lowest bidder.

Heat dissipation may be important (although not necessarily, dielectric
layer mirrors give you 99.9% reflectivity, and if you are using a
multi-meter mirror to focus a laser with a lethal spot size of 10 cm or
so, heating may not be a concern). If you do have extra doohickies to
draw the heat away from the mirror, it will certainly have been a
priority to make sure they do not compromise the ability of that scope
to focus the beam, which means you get just as good resolution when
using it as a sensor.
