        "abstract": "In this paper the effect of an electromagnetic field on the propagation of a pure torsional elastic wave in a conducting circular cylinder is investigated. The general field equations and boundary conditions are linearized and the equations of motion for an infinitely long\ncircular rod are obtained for the particular electromagnetic field configurations considered.\n\nThe torsional motion of a solid rod in a steady axial magnetic field with and without a steady electric field is considered. In the first case it is found that a pure torsional mode will not propagate. In the\nsecond case a pure torsional mode will propagate and its frequency equation is obtained. The results for a perfect conductor are compared to a real material.\n\nThe torsional motion of a hollow rod in a steady tangential\nmagnetic field with and without a steady axial electric field is considered. Without the electric field the equations are completely uncoupled\nand the solution is the standard elastic one. The electric field introduces coupling via the induced magnetic field. The equations of motion are obtained, however the actual solutions are not obtained due to the mathematical complexity involved.",

The pulsing is accomplished by means of cavity Q spoiling techniques utilizing a Kerr cell.  a rotating mirror camera is used with the laser acting as a stroboscopic light source to record the events.  Framing rates of over a million frames per second with exposure times of less than 30 nsec are easily obtainable.  This in conjunction with the highly intense monochromatic, cohere and collimated nature of the laser light makes the high-speed laser camera desirable in many areas of research.",
