Abstract
This paper discusses briefly the principles of gaseous and ruby lasers and makes comparisons of pertinent properties of lasers and conventional light sources. Since the output from a laser is a highly collimated beam of monochromatic light that can be made extremely intense and plane polarized, the eminent suitability of lasers as light sources for photoelasticity is suggested. Lasers are shown to be superior to conventional light sources, especially for the scattered-light method and for high-speed dynamic work. Experiments are described and results are given for using lasers for (1) the scattered-light method, (2) a conventional transmission polariscope with static loads and (3) dynamic photoelasticity.
