The advanced laser turret for me does 360k+1.6M damage per shot, and shoots 100 times per second so it does around 200 million dps and insta kill uber mega raid bosses of doom from the big monsters mod. It kind of would be fine if electricity cost was much higher and it unloaded your whole capacitor bank into one turret but 1 MJ per shot is nothing.
Laser bonus damage 10 researched so +510%
Laser shooting speed 15 researched so +620%

Suggestion:
Make base Cost 10 Mj per shot and scale electricity cost double of the damage increase from research, so if dmg is +100% the energy cost per shot is increased +200%
So for me the new energy cost per shot would be:
Base damage per shot * (Research percentage * added energy cost multiplier) 10x(5.1x2) = 102 Mj per shot
