Consumer grade / privat buyable laser can easily be bought.
And would i destroy a soda can by overheating it slowly and steadily because the can has no easy way of dissipating heat and has electronics in it which are not heat resistent?
Edit: what kind of laser would you be using to pull this off though? the amount of time the satellite would be visible and in range of your beam would be limited. they roughly have the same orbital period as the ISS which I've personally seen many times which is my point of reference. it's only visible for a very short time, so you'd need a very hot beam to work in that time frame. would it be effective as an additive heating. as in, would it cool off before the next time it came within range?
Solar irradiance in LEO is about 1350 W/m^2 when unobstructed. A space-grade solar panel reflects 5%-10% of that back as light, with the rest absorbed as either heat or electricity.
This should give you an idea of what kind of thermal flux the satellite is designed to be dealing with.
Oh come on you guys I thought this would be my ticket to 6000 ;—;
