    Abstract: A method and system(10) are presented for producing exciting radiation (P’) to be used in producing an output coherent anti-stokes Raman scattering (CARS) signal of a medium (12). An input spectral phase coherent optical pulse (P), carrying a pump, a Stokes and a probe photon, is optically processed by adjusting spectral phase and polarization of wavelength components of the input pulse to produce a unitary optical exciting pulse (P’) that carries the pump photon, the Stokes photon and multiple probe photons and is capable of inducing interference between contributions from at least some of vibrational levels in the CARS signal.

    Abstract: A method and device are provided for automatically generating a key and a conjugate key to be used in an optical code division multiple access system. The method comprises applying a down conversion process to pump input light to thereby produce down converted broadband signal and idler fields that are complex conjugates of each other. The signal and idler fields thus serve as the key and its conjugate. Also provided according to the invention is a method for use in coding/decoding a signal in an optical code division multiple access system.

    Abstract: A method and system are presented for producing an output coherent anti-stokes Raman scattering (CARS) signal of a medium. The method comprises generation of a unitary optical excitation pulse that carries a pump photon, a Stokes photon and a probe photon; and inducing a CARS process in the medium by exciting the medium by the at least one such unitary optical excitation pulse. Strong coherent non resonant background, a major problem in single-pulse CARS, is reduced by orders of magnitude by using phase-only pulse shaping or completely supressed by using phase-and-polarisation shaped pulses.
