I was called in to repair this laser about 4 years ago. The turbine had been connected with the phases reversed and had sucked oil from the vacuum pump into the resonator.

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.
