What is the focal length of your LSE ?

Do not use the classical formulas to calculate focused spot size, they do not work with our mirror optics. Our data sheet shows what spot sizes are possible.

To calculate your spot size  = spot size nominal x M^2 x (6/input beam size)

I need to set up a grid as your controller requires a bitmap file. What is the required resolution I need ?

The spot size and overlap  determine the spot separation or grid resolution:

Spot separation = Spot size x Overlap

Resolution = 1 / Spot separation

How do I calculate the required scan speed ?

Scan speed = Spot separation x Pulse Repetition Rate

How much laser power does my application need ?

Average power = Pulse energy x Pulse Repetition Rate
