Locking to a Reference Resonator  
URL: /application-notes/phase-and-frequency-locking-of-diode-lasers/error-signal-generation/locking-to-a-reference-resonator#c15590
The implementation of side-of-fringe locking using the cavity reflection is straightforward, but has the disadvantages described above. Instead, we will focus on a scheme known as the…  
Atomic Spectroscopy Lock  
URL: /application-notes/phase-and-frequency-locking-of-diode-lasers/error-signal-generation/atomic-spectroscopy-lock#c15571
A straightforward optical setup for realizing a spectroscopy lock was already discussed in the application note “Frequency References”. However, to get rid of the Doppler broadening, a different…
