Few if any service lasers "flash," at least not in the visible light
spectrum. Laser designators are usually on only from the report of
"Splash" -- about five seconds. It is a challenge to bring fire to bear

Infrared detection is now cheap and easy, to ~1 micron if you want a
sharp image and out to 10 microns if you don't.
