Abstract

A novel approach for spectral focusing using a single-beam coherent anti-Stokes Raman scattering setup with a pulse shaper controlling the phase and amplitude is presented. By identifying the frequencies acting as the pump, Stokes, and probe, the high degree of control can be exploited in order to specifically and independently tailor the spectral region to act only as probe to achieve the highest signal intensity. While maintaining the optimal excitation of the vibrational coherence, a signal increase by a factor of six in comparison with usual spectral focusing schemes is readily obtained. The signal improvement and contrast is demonstrated on human skin tissue.
