I am currently simulating Selective Laser Melting (SLM) at the nano scale and intend to downscale some of the parameters to establish a correlation between real-life scenarios and the nano-scale model (units :metal).

- The real-life SLM employs a laser power of 400 W. What could be the corresponding power in ev/ps. I am aware that a direct conversion from watts to ev/ps might result in an excessively high value, whereas others researchers have used 400-800 ev/ps (fix heat command).
- Similarly, the real-life SLM has a scan speed of 2000 mm/s. If I convert this to Å/ps, the value becomes 0.002, which seems considerably lower than values used by previous researchers . (moving region command).

I would appreciate any clarification or help
