Paper Abstract

Laser alignment thermal sensitive paper can be used for laser applications such as spot size measurements, beam characteristics, and determining beam mode. Thermal sensitive paper interactions with a 1.54 micron, 35 ns, 3.75 J, Er-Glass laser produced spots that had three concentric zones of response. These spots interact with each other if a minimum distance between exposures is not maintained. The distance needed between spots is directly related to the energy density incident upon the paper. Although there was no lot designation for the box of thermal sensitive papers used in this research, we were able to determine that the response of different papers in the same box could vary under constant laser exposure parameters. Therefore, investigators need to be cautious when extrapolating experimental data from exposures using this type of laser alignment paper.
