Abstract: Based on the phenomenological theory of semiconductors and two-level model, according to the principle of cascading nonlinear system and by analyzing the Lyapunov exponents of its dynamics equations，the chaos disturbance mechanisms of extrinsic photoconductors are surveyed and demonstrated when chaotic laser irradiated. The numerical results have shown that chaotic laser can make the extrinsic photoconductors to chaos.-
