The Wigner distribution function is a powerful mathematical tool for describing the transformations of ultrashort laser pulses as they propagate through optically transparent media with dispersion and Kerr nonlinearity. Since the representations in the quadratic approximation take the form of linear operators in matrix form, a linear theory of laser pulse rotation in phase space "time-frequency" and related theories (theory of time solitons, tomography of optical pulses, fractal Fourier transformations in the time domain) have been developed using the analogy with Wigner-optics in the space domain.
