this is a broken glass rod. the edge the incident beam is coupled to is oval. the slightest change in the position and angle of incidence affects the number of waves in the rod. The opposite side where the fracture has occurred seems to reflect a small portion of the light back to the source, which in this photo looks like a faint standing wave at a 180 degree offset from the main one.
