A Double Discharge High Power Tea CO2 Laser

摘要

A double discharge TEA CO2 laser of simple design and easy operation has been successfully operated. The output energy is 12 joules and the power is 0.5 gigawatt of linearly polarized light. The influence of the different gas mixtures on the problem of arcing, time delay before lasing and evolution in time of the light pulse, has been investigated. The addition of xylene, made possible the operation of a long and narrow laser configuration. Xylene avoids the formation of arcs in a very efficient way. This permits an increase the input energy in the glow discharge. (Author)
