This is nearly the largest laser permitted by the unofficial 
laser DE limit of TL*50 MJ.  A twelve-ton "double barbette"
bay has a length of 8 meters and a width of 4.5 meters.

(I went with this size because there is little difference between
a 750 MJ laser and a 730 MJ laser, and this size is easier for
ship designers to work with.) 

The laser has a standard 2.6 meter tunable lens with an effective 
range of 2400 Mm, reinforced to handle rates of fire of up to one 
shot every 2.5 seconds.  It is nearly able to penetrate an armor
value of 1500 at all ranges.  It can penetrate AV 1000 and still
do appreciable damage.  

In theory, the maximum laser bay could be reduced to ten tons by
using x-ray laser lenses or removing the rapid-fire capability, 
or with shorter-range beam pointers.  Just over nine displacement-
tons are required for homopolar generators, ten cubic meters for
the workstation and beam pointer, and the rest is trainable lens.
