By using a Ti cold-cathode and a gas return path, stable laser oscillation was obtained in a Fabry-Perot resonator-type and a waveguide He-Xe lasers at 3.51 μm. The relations between the laser output power and the total gas pressure, the pressure ratio of Xe gas to the total gas, and the discharge current were measured for the both type of lasers. It became clear that lower pressure and higher discharge current were required for the waveguide laser than for the Fabry-Perot resonator-type laser to get the highest output power when the same value of the pressure ratio was used.<BR>Two types of waveguide laser were constructed by considering the coupling efficiency of the EH<SUB>11</SUB>, mode at the edge of the hollow waveguide. The oscillating characteristics of these two types of waveguide laser were measured and compared with each other.
