Abstract : This patent discloses a laser system using a cw HeNe laser for transmitting a beam through a dichroic into an unstable resonator. A second laser, a cw CO2 laser, has its beam transmitted through the dichroic to follow the HeNe beam into the unstable resonator laser aperture. The resonator's secondary and primary mirrors are adjusted into a parallel orientation which gives a series of circles in both laser beams. The gain-spike is suppressed to eliminate air breakdown.
