Formation and operation parameters of sic electrodes in laser discharge

Abstract EN

In this work, laser discharge electrodes were fabricated using SiC composite as a base material.

The electrodes were also fabricated by adding copper to the composite material under different formation conditions.

These electrodes were employed to operate discharge system of a TEA-CO2 laser.

Operation parameters were studied considering several influences such as reduction factor, grain size, forming pressure, sintering time and temperature, and copper added ratio.

Also, the electrical characteristics, such as conductivity, electric discharge uniformity and current pulse shape, were introduced.

It is aimed to optimize the experimental conditions leading to produce the discharge electrodes suitable for stable and long-life operation of laser system.
