Abstract

Plastic hollow waveguides with different thicknesses of the dielectric layer were investigated. The AgI layer thickness (t) was found to be the main parameter which affects the transmission of radiation in the hollow waveguide. Waveguides with t equals 0.84 micrometers have a minimum attenuation for CO2 laser energy transmission ((lambda) equals 10.6 micrometers ). However, waveguides with t equals 1.32 micrometers have high attenuation, so they can be used as filters for this specific wavelength. The influence of the iodination parameters such as iodination time, concentration of iodine solution, and temperature of reaction on the dielectric layer thickness were also investigated. It was found that t rises with iodination time (r) as t equals r0.37, I2 concentration (parabolic form), and reaction temperature.
