It's worth bearing in mind that lasers are still only one tool with its own set of limitations in an entire toolbox. The thing about lasers is that it's impossible to intercept and always dumps 100% of its energy into a traget, unlike kinetic impact weapons that may be affected by overpenetration and angle of impact. Against relatively fragile and fast targets (drones, smaller aircraft, missiles etc.) this is ideal, as you don't have to worry about things like leading your shot or overpenetration causing little damage beyond a small hole. On the downside, this makes current lasers ineffective against any meaningful armour or cover in combat relevant timeframes. The same trait that makes lasers desirable for their current niche also hinders it in some others. At the end of the day, until technology in power sources advances sufficiently we're unlikely to see much laser usage in ground combat.
