A quick question about this type of apparatus. The apparatus itself is composed of 2 concentric hollow cylinders. The cylinder at center is cooled below -50C. The atmosphere around the outer cylinder is at room temperature. This creates a temperature gradient in the space between the cylinders. The index of refraction increases as distance from the center cylinder decreases.
Question: If a laser is pointed into a perfectly transparent spot on the outer cylinder, could the laser beam be refracted to orbit the inner cylinder given the space is large enough for such a small change in refractive index
