Abstract

The effect of post-irradiation of CO₂ laser at wavelength of 10.6μm, as a coherent source, on the alpha irradiated polyallydiglycol track recorder has been investigated to study the detector characteristics due to the corresponding morphology modifications. The average bulk etch rate and the mean diameter of alpha tracks are studied at several laser powers. In addition to this, absorption of the irradiated samples have also been investigated from 200nm to 600nm to observe the change in optical band-gap and it is concluded that the variation in the mean diameter of alpha tracks is probably linked to the variation in optical band-gap.
