I would like to learn how to calculate whether a laser can burn through a material, or not. For example right now I need to calculate whether a laser from a DVD burner (which supposedly is max. 400 mW strong) can burn through steel.
I can imagine that I need to know the power of the laser in mW, the wavelength of the light it is emitting, the melting and boiling temperature and thermal conductivity of the material it is shining on. Also, I guess some optical properties will be important but I don't know which.
The Attempt at a Solution
So far I gathered data on thermal properties of steel and other materials and power and wavelength of the laser.
Thank you very much for your help
