The optic duplex modulation performed by using two kerr cells at the optic transmitter. The signals are recoverable at the receiver by using photodetector to respond the appropriate polarization components of light. The application of duplex modulation is to eliminate the noises due to atmospheric turbulence. The results of experiments shows that the atmospheric turbulent noises are really eliminated by the method. Finally the advantages and disadvantages to use kerr effect rather than pocket effect for optic modulation system are compared.

A model that uses a continuous, distributed, and moving heat source to describe the temperature profile for laser-drilled-holes has been developed. A new mathematical approach has been systematically performed in detail. The temperature profile of the laser-formed hole are calculated to indicate the magnitude of thise factors that can influence the process of the removal of materials. A modified CO2 laser system, based on double-pulse-discharge technique [1], has been set up. Using this modified laser system, the experimental results are found to be in agreement with the mathematical analysis.
