Splet01. nov. 2024 · Fig. 1 shows the typical layout of the PDH stabilization system, including all relevant optical and electronic devices. The basic idea is that the cavity length can be measured by the laser frequency and vice versa. This creates an error signal around the resonance of the cavity, which is proportional to the deviations in the length. SpletThe system design is centered around a Fabry-Pérot (FP) cavity which is composed of two mirrors optically contacted onto the ends of a cylindrical spacer made of Ultra-Low …

SpletThe main innovation of the PDH technique is to monitor the derivative of the cavity transmission with respect to detuning, rather than the cavity transmission itself. Unlike a side-of-fringe lock, this allows the sign of the feedback signal to be correctly determined on both sides of resonance. SpletImplementation problems Up: Kohn's method Previous: Kohn's method Contents Variational principle. As mentioned in section 4.4.3, Kohn [] has suggested the use of a penalty functional to impose the idempotency condition, and has proved a variational principle based upon it.We consider trial density-matrices expressed in diagonal form with real …
