Click For Summary
Cesium atomic clocks operate based on the vibrations of cesium atoms, which oscillate at a precise frequency. These clocks measure time by counting the oscillations of cesium atoms transitioning between energy states. The accuracy of cesium atomic clocks stems from the stability of these oscillations, making them essential for global positioning systems and telecommunications. For further understanding, a recommended resource is a paper from NIST that delves into the principles and functioning of cesium atomic clocks. This foundational knowledge is crucial for advancements in timekeeping technology.
I am observing an irregular, aperiodic noise pattern in the reflection signal of a high-finesse optical cavity (finesse ≈ 20,000). The cavity is normally operated using a standard Pound–Drever–Hall (PDH) locking configuration, where an EOM provides phase modulation.
The signals shown in the attached figures were recorded with the modulation turned off. Under these conditions, when scanning the laser frequency across a cavity resonance, I expected to observe a simple reflection dip. Instead...
