CPTL representation of contributing to the signal. (i) and (ii) represent the two terms in Eq. (13), respectively. The interaction with the detected mode is chronologically the last.

The pulse configuration [Eq. (28)] consists of a broad-band pulse (dashed-green line) and a narrow-band pulse (red-filled line) centered at . Raman resonances at modulate the broad pulse envelope (blue-solid line).

FIG. 4.

The Stokes contributions to the CARS signal from processes starting at state for various values of , as indicated. The dissipative part of the signal (solid-dark line) given by Eqs. (31) and (34), the parametric part (dashed line) given by Eqs. (30) and (33), and their sum (thick-blue line). The dissipative part of the signal corresponds to a Stokes process, namely, the transition . The width of the signals is determined by , the width of the narrow-band peak. Including the anti-Stokes contribution would reduce the signal without changing the lineshapes.
