TL;DR: In this paper, a comparative study involving transmission, reflection and photoacoustic FTIR techniques is presented with analysis of polyamide-6 with a 1.5 MeV electron beam with a 500kGY dose, in the presence of O2.
Abstract: A comparative study involving transmission, reflection and photoacoustic FTIR techniques is presented with analysis of polyamide-6. The potential and limitations of these methods are investigated by analyzing structural variations that take place at the surface in the bulk in recycled and irradiated polyamide-6 with a 1.5 MeV electron beam with a 500kGY dose, in the presence of O2. FTIR techniques appear to be sensitive in detecting small structural changes that occur in recycled and irradiated polyamide-6. The analysis of samples indicated the formation of ¾OH, HOC=O-, - C=O groups. Also, small structural changes were detected which are characterisitic of NH and ¾CN-C=O groups. Transmission techniques show better the structural changes in the bulk, and microscopy-FTIR appears to be more sensitive in detecting what occurs at the sample surface.

TL;DR: A general approach for the optimization of single-lamp, cw-pumped Nd:YAG lasers is developed and mode locking with 56-ps pulse duration at 33 A of lamp current and up to 13 W of average output power is demonstrated.
Abstract: Measurements of the bifocal, thermally induced lenses of a cw Nd:YAG laser were obtained. We observed four different focal lengths that are polarization and direction dependent. The focal lengths were used to design stable resonators with large fundamental mode filling in the laser gain medium. The beam is totally polarized in the desired direction even without an intracavity Brewster window. We developed a general approach for the optimization of single-lamp, cw-pumped Nd:YAG lasers. Up to 22 W of cw output power in the vertically polarized TEM00 mode and 15 W in the horizontal polarization are obtained for moderate lamp currents. Also, we demonstrate mode locking with 56-ps pulse duration at 33 A of lamp current and up to 13 W of average output power.
