I know there are essentially two steps to it, where the latter part is the ‘zap zap’ gun where you can see the ink lifting and a whitish patch remains (which I hear can be as painful as getting the tattoo). What is it about the laser that helps to lift or burn the ink out of the skin?

Tattoos stick around because the clumps of ink are too large for your immune cells to effectively attack and remove them. They still try, certainly, and they still make progress which is why tattoos fade over time.
Laser removal blasts the clumps of ink with focused heat so that they break down into smaller pieces which your immune cells can actually handle. It’s a bit like trying to eat a giant jawbreaker and it takes forever because you can’t even fit it in your mouth so you’re just slowly licking it; and then you get a hammer and shatter it into manageable pieces.
Laser removal usually takes several rounds over months to completely break up the large pieces and potentially many months more for your body to fully break down and remove the ink.
