This paper provides a simple physical consideration of a new type of squeezed state of light: space-time squeezed state. As it was shown recently, spatial-multimode broadband squeezed light can generate (by homodyne detection) photon counting statistics that are regular not only in time, but also in the plane of observation. A possible advantage of application of space-time squeezed light in a number of areas of quantum optics (i.e., low-noise generation, detection of optical images, Fourier optics, and holography) is discussed from an elementary point of view.
