Abstract: An unstable laser resonator system which provides an output beam with enhanced power, energy distribution and optical characteristics is disclosed. Two separate regions of gain medium each of which has the maximum dimensions permitted by the physical constraints of superfluorescent and excited population decay characteristics resonate in a split mode optical cavity having a common interlocked region of resonance which incorporates the contributions of each gain medium and combines the composite intracavity mode prior to output coupling from the resonator. The resonator system produces a coherent, phaselocked, high power, symmetric output beam. Optical cavities based on both spherical and cylindrical optics are discussed.

Abstract: Laser systems which are pumped by an electric discharge formed in a gas are disclosed. The discharge is in the form of a vortex stabilized electric arc which is triggered with an auxiliary energy source. At high enough repetition rates residual ionization between successive pulses contributes to the pulse stabilization. The arc and the gain medium are positioned inside an optical pumping cavity where light from the arc is coupled directly into the gain medium.
