abstract={The aim of this paper is to find the effect of Nd: YAG laser of wavelength (532 nm), laser power 150 MW on the CR-39 polymer. Twenty three detectors were divided in to three sets. The first set (ten detectors) (post-exposed) was first exposed to alpha radiation from <SUP>241</SUP>Am source at 3MeV and then treated in air with laser at different exposure time started from 10 minutes to 100 minutes with ten minutes differ between them (alpha + laser). For the second set (ten detectors) (pre-exposed), the process was reversed (laser +alpha) under the same conditions, for the last set (three detectors) (un-exposed to laser), used as a control set, was irradiated with an alpha source (241Am). Alpha track diameters, bulk etching velocity (V<SUB>B</SUB>), track etching velocity (V<SUB>T</SUB>), etching efficiency (¦Ç), etching ratio (V) were determined. The activation energies of bulk etch (E<SUB>B</SUB>) and track etch (E<SUB>T</SUB>) for unexposed, post- exposed and pre-exposed are found to be equal to 1.10, 0.92, 0.82 eV and 1.07, 0.86, 0.79 eV respectively.},
