The production of Bose approximation coherent states and SU(2) coherent states of electron-hole pairs in semiconductor generated by coherent light excitation are discussed. Squeezed fluctuation and recombination radiation of electron-hole pairs are studied for these two cases. The second order coherence and distribution functions of electron-hole pairs are given. It is shown that the Bose approximation corresponds to the contraction of group SU(2) to the harmonic-oscillator group.
