WebIn both cases the reason is the enormous speed, often tens of kilometers per second. When a larger object enters the atmosphere at these speed the air in front of it gets compressed so much that it becomes extremely hot. (Think of pumping up a tire; you're also compressing air and you can feel the valve becoming hot.) WebMaterial 1 melts at approx. 140°C, material 2 at 230°C – with 200 W laser power, one can therefore cut material 1 faster than material 2, as the energy doesn't have to be applied for as long to material 1 as to material 2.
