Latest Patents
Michael W Barrett holds a patent for "Sealed-off, RF-excited gas lasers and method for their manufacture." This patent describes an improved sealed-off RF-excited gas laser and the method for its manufacture. The resonator section of the laser consists of four optically reflecting longitudinal walls that define the laser bore and plasma section. A concave mirror is mounted on one end of the resonator, while a flat or concave output coupler is mounted at the other end. The laser resonator operates in a non-waveguide, non-free space mode utilizing wall reflections. Artifacts are introduced at the optically reflecting walls to define a stable oscillatory axis and mode structure by favoring the establishment of stable reflection points along the length of the walls. These artifacts are created by carefully defined bends and tapers in some of the walls to create high mode purity, stability, and relatively uncritical optical alignments. Manufacturing methods are disclosed to speed up passivation of the sealed enclosure by internal preexposure of the sealed envelope to oxygen-helium plasmas created at different temperatures, pressures, and peak power than seen in the subsequent laser operation.
