By photo-thermally exciting a medium, with infrared laser light, a barrier can be formed due to abrupt changes in compressibility of the excited medium. In this work, we demonstrate for the first time, the ability to generate THORS barriers in ambient air. Additionally, the temporal dynamics of THORS barriers, in ambient air, were characterized by using ultrasonic transducers.9 pagesen-US© 2022 Society of Photo-Optical Instrumentation Engineers (SPIE).
