What happens to flow in a constant area duct when there is a pressure gradient?

In nozzles and diffusers the cross-section area follows the one defined by the pressure gradient. In a nozzle it decreases to keep mass flow rate constant. In a diffuser the...

Why does the LASER beam quality factor (M^2) use squared value?

Why does the LASER beam quality factor (M^2) use squared value? Why not using just M? i.e., Why define beam quality factor as $M^2 = frac{BPP_{Real}}{BPP_{fundamental}}$ not $M...
