Let us play around a little with the reduced single pulse MPEr assuming it is the most
restrictive criterion.
Dimensions and definitions:

Length
m
mm  Time
s   Angle  Solid Angle
sr Power
W  Energy
J  Standard aperture: Counting time for pulses: for a point source
Expression for MPE of the standard: Remember C5:=N^-0.25, when N = number of pulse during T2.
The duration function is given as duration function with:
a see above
d = beam diameter
T = cycle time of the figure = 1/f
r = radius of the moving dot
in the spectator's area
s = 1 second
We take a safety factor because of the higher intensity close to the center of the beam. From this you can calculate the Watts in the beam of diameter d in the spectator's plane. To follow this simplification keep in mind the factor n*t with n= T2/T
and the speed of the dot, given by 2*p*r/T.
As you can see the formula is independant of the cycle time T (hence the
frequency) of the figure. The result will be Watts, the total power of the beam.
Now assume some data:    This value comes to the same order of magnitude as in the example you sent to here.
Now I try to come to 10 W???
