中央激光设备位于阿根廷皮埃尔·奥格天文台的中央附近。它的特点是一个紫外线激光器和光学元件，可以将一束校准的脉冲光引导到天空中。从这束光散射出来的光在俄歇光学探测器中产生轨迹，这些探测器通常记录宇宙射线空气阵雨中的氮荧光轨迹。中央激光设备充当“测试光束”，用于研究大气和空气荧光探测器的特性。此外，激光可以通过光纤发送光脉冲到最近的表面探测器槽。该信号与射向天空的光线同时发生，用于天文台表面和荧光探测器的混合定时分析。
The Central Laser Facility is located near the middle of the Pierre Auger Observatory in Argentina. It features an ultraviolet laser and optical components that direct a beam of calibrated, pulsed light into the sky. Light scattered from this beam produces tracks in the Auger optical detectors, which normally record nitrogen fluorescence tracks from cosmic ray air showers. The Central Laser Facility acts as a ``test beam' that is used to investigate properties of the atmosphere and the air fluorescence detectors. Additionally, the laser can send a light pulse via optical fiber to the nearest surface detector tank. This signal, which occurs simulateously with light beamed into the sky, is used for the hybrid timing analysis of the surface and fluorescence detectors at the Observatory.
