An exact analytical expression for the time–bandwidth product ΔtΔf of chirped sech2 pulses is derived. The relation can be expressed by ΔtΔf = 0.1786 arcosh(cosh πα + 2) as a function of the laser’s phase–amplitude coupling factor α. An experimental measurement of the α factor that relies on this formula is discussed.
