These techniques require only minor modifications to the standard pound drever hall locking techniques and have the advantage of not altering the intrinsic stability of the frequency reference.
Most cavity lengths are sensed using radio frequency phase modulation sidebands added to the main beam by the electro optic modulator via the pound drever hall laser stabilization technique 25.

The phase of the reflected light at the carrier frequency represents a time average of the incident laser phase and frequency.
The pockels cell actually modulates the laser s phase but the distinction between phase and frequency modulation is irrelevant for the conceptual model.
Physical optical and electronic aspects of this discriminator laser frequency stabilization system are considered in detail.
We describe a class of techniques whereby a laser frequency can be stabilized to a fixed optical cavity resonance with an adjustable offset providing a wide tuning range for the central frequency.

We describe a new and highly effective optical frequency discriminator and laser stabilization system based on signals reflected from a stable fabry perot reference interferometer.
The stabilization of the carrier envelope offset phase or frequency of a mode locked laser ceo stabilization can be based on e g a phase measurement with an f 2f interferometer and feedback via some wedge or tilted mirror in the laser resonator.

This instability is primarily due to temperature variations mechanical imperfections and laser gain dynamics 4 which change laser cavity lengths laser driver current and voltage fluctuations atomic transition widths and.
Thus with suitable design the servo loop bandwidth is not limited by the cavity response time.
