    • A phase-locked ridge waveguide gas laser includes a body having two major and two minor limiting surfaces together circumferentially bounding an internal space within the body, which contains a gaseous lasing medium. The gaseous medium is excited at radio frequency with attendant light emission from the gaseous medium. Mirrors are so positioned relative to the body as to provide lasing of the light emission. Respective ridges partition the internal space into at least three laser resonator cavities each sustaining a guided mode of the lasing light emission. The ridges extend in an alternative fashion from one and the other of the major surfaces of the body into the internal space and terminate short of the respectively other of the major surfaces to provide respective gaps. Each of these gaps connects two adjacent ones of the laser resonator cavities for phase-locking the guided modes in such cavities. However, the alternation of such gaps between the other and the one of the major surfaces provides discrimination against higher-order transverse modes.
    • 锁相脊波导气体激光器包括具有两个主要和两个次要限制表面的主体,所述两个主要和两个小的限制表面一起周向地限定在主体内的内部空间,其包含气体激光介质。 气体介质在无线电频率下被激发,伴随着来自气体介质的光发射。 镜子相对于身体如此定位,以提供发光的激光。 相应的脊将内部空间分成至少三个激光谐振腔,每个激光谐振腔保持激光发射的引导模式。 脊以替代方式从身体的主表面的另一个延伸到内部空间中,并且终止于主要表面的另外的另一个,以提供相应的间隙。 这些间隙中的每一个连接两个相邻的激光谐振腔,用于将这些空腔中的引导模式相位锁定。 然而,另一个和主要表面之一之间的这种间隙的交替提供了对高阶横向模式的区分。
