Abstract:

Initial results indicate that transversely RF excited 2W CW CO2 waveguide lasers can be built to last in excess of 10000 hours. This result has been achieved with either internal electrodes or capacitive wall coupling and with either CO-or N2-bearing gas mixtures. On-off switching seems to be quite well tolerated. RF conductance and starting voltage measurements for six different gas mixtures and four pressure parameters are given. Keywords Carbon dioxide waveguide lasers 2 Watt Continuous Wave lasers Lifetest results Radiofrequency excitation Electrode and electrode-less Carbon monoxide and Nitrogen mixtures On-off switching life and Radiofrequency gas conductance and starting voltage measurements.
