Laser handguns are probably never going to be a thing. How many places are there on a human body where a cauterized hole a few mm across will kill or incapacitate someone? How likely is someone going to be to hit those places accurately with a pistol? There are some interesting niche uses for laser sniper carbines[1], IMO, like punching holes in a gas tank and igniting the vapour, burning out security camera sensors, cutting power/communications lines, starting fires inside distant buildings by firing through windows, etc., but I think most useful laser weapons will be mounted and computer-controlled so that they can track moving targets long enough to do meaningful damage. [1] It's not a rifle if the bore is smooth.
