Using Laser diode to remove copper layer from PCB

laser diode laser

My questions are as following: What type of laser diode I need to use to remove 1 mm thick paint layer? How can I calculate the minimum power I need to ablate the paint layer?

I used a 808nm 0.5W laser diode and it can remove paint from over the copper layer.

An ordinary laser diode won't cut it. You need something like a Q-switched laser, pulsed at 10's of kHz.
