This paper firstly reports the operation and characteristics of a completely sealed BN waveguide CO2 laser with an operating time of over four hundred hours.
Effects of gas constitution and electrode material on the life-time of sealed-off CO2 lasers have been studied. It is pointed out that the removal of N2 is an important factor affecting the life-time. CW operation life-time of the laser has been obvi
An analysis of the deteriorating mechanism of the coating has been made and a formula for design of coaxial anode has been deduced. Adopting this method and combining with the CO2 catalytic regeneration technique, we have developed a glass wave-guide
Results on a partly sealed-off CO2 laser different from the traditional structure are given. Output power of about 71 W for one meter of discharge length has been obtained.
