We analyze the effect of damping (absorption) on critical self-focusing. We identify a threshold value $\delta_{th}$ for the damping parameter $\delta$ such that when $\delta%gt; \delta_{th}$ damping arrests blowup. When $\delta < \delta_{th}$, the solution blows up at the same asymptotic rate as the undamped nonlinear Schrodinger equation.
