Abstract: A radio-frequency excited carbon dioxide (CO2) or carbon monoxide (CO) gas laser includes two electrodes, which have passivated surfaces, within a sealed housing. Features in a ceramic slab or a ceramic cylinder located between the electrodes define a gain volume. Surfaces of the ceramic slab or the ceramic cylinder are separated from the passivated surfaces of the electrodes by small gaps to prevent abrasion thereof. Reducing compressive forces that secure these components within the housing further reduces abrasion, thereby extending the operational lifetime of the gas laser.

Abstract: 一种用于可调激光器的反射镜结构和可调激光器。可调激光器采用超结构光栅作为反射镜（08），超结构光栅所在区域的周围形成悬空结构，利用悬空结构形成热隔离，提高热阻，减少了热量流失，使得热量集中在超结构光栅所在区域，从而能够提高反射镜（08）的热调谐效率，有利于降低可调激光器的整体功耗。同时，通过设置底部支撑结构（10d）为悬空结构提供底部支撑，能够增强悬空结构的机械强度。另外，任意两个底部支撑结构（10d）在超结构光栅中对应的区域落在超结构光栅的空间周期中的不同位置，有助于在热调谐时避免超结构光栅的反射谱的平坦性恶化，从而有助于避免可调激光器性能的恶化。
