    Abstract: Apparatus for the selective excitation of a gaseous region including a chamber enclosing a gas and containing cathode means having a plurality of portions positioned in a first predetermined pattern, and anode means having a plurality of portions positioned in a corresponding pattern. A voltage normally insufficient to cause conduction is impressed between anode and cathode and scan means is provided for causing successive corona discharges which sequentially establish charge carriers in the space between successive portion of the cathode and successive portions of the anode. The charge carriers, in turn, enable heavy conduction between cathode and anode in successive regions of space. The scan means thus addresses the heavy conduction, which can be viewed directly, as in a plasma display device, or used to establish desired modes od oscillation in a laser capable of a plurality of modes of oscillation.

    Abstract translation: 用于选择性激发气体区域的装置，该气体区域包括包围气体的腔室，并且包含具有以第一预定图案定位的多个部分的阴极装置，以及具有以对应图案定位的多个部分的阳极装置。 通常不足以引起导通的电压被施加在阳极和阴极之间，并且提供扫描装置用于引起连续的电晕放电，其依次在阴极的连续部分和阳极的连续部分之间的空间中建立电荷载流子。 反过来，电荷载体在连续的空间区域中能够使阴极和阳极之间的重导通。 因此，扫描装置解决了如等离子体显示装置中直接观察的重传导，或用于在能够进行多种振荡模式的激光器中建立振荡的所需模式。
