Abstract
Tunable femtosecond laser pulses in a large spectra range of 0.41 to 5.5 micrometers are used for noncollinear two-photon absorption in condensed matter. The spectral properties of two examples are discussed in detail: diamond of type IIa and neat water at room temperature. The generation of free carriers and results on the subsequent relaxation dynamics are presented.
