First CO2 laser

My first CO2 laser built back in 1998-9. Using 22mm copper fittings and 22mm borosilicate glass epoxied with JB weld. It ran for about 3 hours of operating time before thermal stresses round the electrodes fractured the tube. Pictures include damage to a Compuserve CD and 3mm glass.
