Is there an equation what describes a relationship between the undamped natural frequency and a bandwidth of this system?

I have following 2nd order system: (2*d*w0*s+w0^2)/(s^2+2*d*w0*s+w0^2) where "w0" is the undamped natural frequency and "d" is the damping. Is there an equation what describes a relationship...
