One notes the momentum and expectations are growing and progress is being achieved in many fronts as previous investments are starting to pay off. Here's more detail on progress achieved in allowing airborne lasers to deal with turbulence.
Adaptive optics are useful for turbulence (wind), not for dealing with moisture in the air. Moisture is an attentuation problem (laser energy getting absorbed by water molecules in the air). There's not a whole lot you can do about it other than go somewhere it isn't or try to power through (which has its own problems).

SUNNYVALE, Calif., Oct. 15, 2015 – Because enemy aircraft and missiles can come from anywhere, a laser weapon system on a military aircraft will need to be able to fire in any direction. However, the laws of physics say that a laser only can engage targets in front of an aircraft that is travelling close to the speed of sound – unless atmospheric turbulence can be counteracted. That’s exactly what Lockheed Martin (NYSE: LMT) has done in developing a prototype laser turret for the Defense Advanced Research Projects Agency (DARPA) and the Air Force Research Laboratory (AFRL), paving the way for laser weapon systems on tactical aircraft.
