Can someone please help me with plotting this function of the Gaussian Beam wavefront radius?!

Given: Power and energy (but i don't think these have anything to do with the plotting). Also the wavelength of the laser is given (248 nm). Nothing else is given....
I need to plot R(z).

calculate: w0, lambda and set them as variables. i am guessing lambdaL=248
clc
clear
close
%
w0=4;
lambda=2;
z=1:1000; %or your wanted plotted values
beamradius=w0*sqrt(1+((lambda*z)/(pi*(w0).^2)).^2);
%
plot(z,beamradius,'r')
title('blabla bla')
xlabel('blab bla bali') % x-axis label
ylabel('blab bla bali') % y-axis label
legend('z = whatever','Location','northwest')
check for units
