The simulation of the effect of a pulsed laser beam
“In the simulation of the effect of a pulsed laser beam on a material, it is often assumed that it is sufficient
to have the average laser energy over time, i.e. the average laser power, as input for the simulation. As
such, the pulse repetition rate, the changes in laser energy over a single pulse, and that there is no laser
energy delivered to the material in between pulses, can be neglected.”
Is the above assumption valid or of sufficient accuracy at a pulse repetition rate of
(a) 1000Hz, (b) 1Hz or (c) 0.001 Hz respectively
(i) a polymer substrate and
(ii) a copper substrate.
Your answers should provide proper justifications and explanations. Do state any necessary assumptions.
