ApexProxy, many thanks for your reply. The paper and the pointer would be moving in relation to each other which would help with an overheating problem until the amplitudes became very small. I had anticipated a little circuit to detect this situation and shut down the laser. Can the output of...

Thanks for your interest. The pendulums are supported on fulcrums about 3/4 of their length from the mass. which is a cast lead block weighing about 3Kg. The pen and paper are mounted at the other end of the rods. The fulcrum distance is variable as is the position of the mass in each case...
