Abstract

On the basis of the recently introduced definition of energy spectrum of a partially temporally coherent pulse train [Opt. Lett. 29, 394 (2004) ], we show that the well-known time–frequency uncertainty relationship applicable to a fully temporally coherent pulse train is still correct for a partially temporally coherent pulse train. The condition under which the uncertainty relationship reaches equality is derived. An example is presented to illustrate the validity of the uncertainty relationship.
