Would blinding your enemy with an autotracking laser be practical in a dogfight XD?
at the edge of.
You would need a laser system that would recognize the target and auto track in a turn. However 1) by convention such weapons are generally banned. The protocols on blinding lasers specifically forbids weapons designed to permanently blind people.
2) even if you ignore that. Blinding the pilot in a close dogfight is dangerous to you as well as the other guy basically becomes uncontrolled and could crash into you.
3) even if you do temporarily disorient the other pilot his systems may still establish a target lock on.
It takes longer for a human to react to sight than to sound. All missile systems give audio cues specifically so that in the event of lock on the pilot can squeeze the kill button just that much faster.
4) many nations are looking into counter laser protection. Coatings, filters and the like to prevent flash blindness.
5) blinding the pilot doesn't nessisarily help you if there is a second seater.
Frankly I would rather that laser blind the IR air to air missiles, FLIR or burn out the radar seaker
