BICOLOR OPTICAL TREATMENT OF MULTI-LAYERS FILM SAMPLES

In the present paper, we study the influence of simultaneous polarized optical treatment (10 ns Nd: YAG lasers with wavelengths 1064 nm and 532 nm with power density 0.6 GW/cm2) together with electrostatic dc electric field (up to 8 kV/cm) on self-assembled multi-layer film samples. The second-order optical susceptibility (SOS) achieves the maximal values after one minute simultaneous dc electrical-optical treatment. Further treatment will not enhance the values and even leads to the decrease of SOS. The independent measurement of the local temperature shows that local heating does not exceed 10.1 K.
