The results of third-order nonlinear susceptibilities studies of Fe- and Zn-doped
polyvinylpyrrolidone (PVP) aqueous solution in processes of third harmonic generation of
Nd:YAG laser radiation are presented. Nonlinear susceptibilities of PVP:Fe and PVP:Zn
were calculated to be 
esu and 
esu respectively. Third harmonic conversion
efficiencies in these metallocomplexes were measured to be 
and 
respectively. The Z-scan method was applied to determine Kerr effect influence on
frequency conversion process. The value of nonlinear refractive index of PVP:Fe at the
wavelength of 
nm was measured to be 
esu.
