Abstract
The effect of coupling two chaotic Nd:YAG lasers with intracavity KTP cryst al for frequency doubling is numerically studied for the case of the laser operating in three longitudinal modes. It is seen that the system goes from chaotic to periodic and then to steady state as the coupling constant is i ncreased. The intensity time series and phase diagrams are drawn and the Ly apunov characteristic exponent is calculated to characterize the chaotic an d periodic regions.
