Rectangular Light intensity profile over a surface

I am trying to model a laser pulse which has a rectangular shape in 2D axisymmetric domain.
I have already modeled a Guassian shape with the equation: I0*exp(-2*(r/W)^2) as the boundary condition, where: I0: peak light intensity
r radial direction (i.e. the x axis) (Y axis is light falling on the surface)
W: beam width.
How do I express rectangular shape in mathematical expression using either step function or rectangular function?
Please suggest some ideas.
Thank you,
Ishan
