Abstract

The phase control strategies of Coherent Anti-Stokes Raman Scattering(CARS) process using femtosecond pulse-shaping techniques are analyzed. Different local and broadband control strategies are compared. It is shown that shaping probe pulse alone is sufficient for the local signal and background control, while keeping pump and Stokes pulses in transform limited forms. It is found that π step phase has good performance in the peak resonant signal enhancement and background suppression at ώ_as = Ω_as in general. Proper combinations of different phase schemes may achieve better performance in some cases.
