The effect of laser radiation on the impurity energy spectrum of intercalated structures is studied by the example of <Co>{sub 0.015}GaSe. By the variations in frequency dependences of resistivity measured normally to the layers of the obtained structure and by the transformation of the Nyquist diagrams consisting of two connected in series parallel R -parallel C units, a conclusion is made on the laser-stimulated compensation of the intercalant. The obtained values of the real part of permittivity are characteristic of doped semiconductors or their alloys in the radio-frequency range. The experimental results showed that the pulsed laser irradiation is an effective method to affect the energy impurity spectrum of intercalated compounds.
