Noncollinear phase-matched nonresonant four-photon frequency mixingωp+ωpωLωs in crystals and aqueous solutions of LiCl, CsCl, KF, and KI is studied. The concentration of the aqueous solutions is varied between 0.5 mol/l and saturation. Picosecond laser pulses of a mode-locked Nd-glass laser are applied as pump pulses. The energy conversion of laser light at frequencyωL to frequencyωS is measured and the nonlinear susceptibilities χ(3) are calculated. The dependence of the hyperpolarizabilities on concentration is analysed and gives information on the solute-solvent interaction.
