Abstract : A new experimental system, utilizing photothermal deflection techniques, does test measurements of guided wave propagation attenuation in optical thin films. Lessons are drawn from propagation attenuation in wave guidance optics in order to characterize the losses and qualities associated with high quality optical thin films. Experimental results clearly show that attenuation coefficients are capable of very sensitively and completely reflecting thin film properties and quality. (AN)
