You have two approaches. Find the DMD device with the greatest power
handling that is in your budget, then back-calculate if that is sufficient
for the 'pixel' size you need on your sample for successful activation.
Alternatively, calculate the energy density per unit area per pixel you
need for activation and shop based on that number.
