The IR CO laser (wavelength 5.5 lm) pumping power I p treatment shows significant enhancement of the optical second harmonic generation in layered CdI 2 -Cu crystallites at thickness below 10 nm. For the relatively thick layers (higher than 15 nm) the SHG dependence manifests a slight decrease (at I
