A highly efficient multi-joule output TE-CO2 laser has been developed using a spiker-sustainer excitation method. With helium-free laser gas mixtures 5-J laser pulses have been produced at a pressure of 400 mbar with an energy output efficiency of 22.6%. The addition of small amounts of hydrogen to the gas mix has been found to enhance laser performance.
