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.

A method for use in inducing a Coherent Anti-Stokes Raman Scattering (CARS) signal from a medium, the method comprising shaping a unitary optical pulse carrying a pump photon, a Stokes photon and a probe photon and producing a unitary optical excitation pulse, said shaping comprising blocking a spectrum of the unitary optical pulse in an expected spectral range of the CARS signal, the method thereby enabling inducing and detection of the CARS signal from the medium by application of said unitary optical excitation pulse to the medium.
A system for use in inducing a Coherent Anti-Stokes Raman Scattering (CARS) signal from a medium, the system comprising a pulse shaper for accommodating in an optical path of a unitary optical pulse carrying a pump photon, a Stokes photon and a probe photon and being configured and operable to shape the unitary optical pulse into a unitary optical excitation pulse, the pulse shaper comprising a block element for blocking a spectrum of the unitary optical pulse in an expected spectral range of the CARS signal, and a programmable shaping assembly operable to modulate a spectral phase of the unitary optical pulse by a desired spectral phase function and assign a desired phase to each of the unitary optical pulse wavelength components.
