  • High power gas laser amplifier
    Patent number: 4264868
    Abstract: A high power output CO.sub.2 gas laser amplifier having a number of sections, each comprising a plurality of annular pumping chambers spaced around the circumference of a vacuum chamber containing a cold cathode, gridded electron gun. The electron beam from the electron gun ionizes the gas lasing medium in the sections. An input laser beam is split into a plurality of annular beams, each passing through the sections comprising one pumping chamber.

  • Efficient laser amplifier using sequential pulses of different wavelengths
    Patent number: 4200846
    Abstract: A laser oscillator output pulse is separated into a plurality of separate beams which are temporally or spatially individually amplified by a power amplifier. The beams may then be recombined to provide a more powerful output than conventional single beam amplification.
