dc.description.abstract When a heated pipe is rotated, the dynamics of the gas inside exhibit properties reminiscent of a solid-state positive lens. The properties are a result of a parabolic distribution of refractive index in the pipe which is caused by mixing of hot and cold gases. When a laser beam was propagated along the pipe’s axis a focal spot was observed. Experimental data to demonstrate how the lensing properties depend on pipe rotation speed and pipe temperature is presented. A numerical model using the basic equations of a Graded Refractive INdex (GRIN) lens provides a further tool to analyse the propagation of laser beams through this system en
