Optical cavity is created two mirrors at both ends of the laser. Laser mirrors serve two goals: 1.Increase the length of the active medium, by making the beam pass through it many times. 2.Determine the boundary conditions for the electromagnetic fields inside the
optics external to the laser chip in order to form a longer cavity. A laser cavity built in this manner is often called an ECDL, “extended-cavity diode laser,” or “external-cavity diode laser.” The use of frequency-dependence reflection for the external cavity (e.g

10/1/2012· Abstract: We present a novel and simple method of stabilizing the laser phase and frequency by polarization spectroscopy of an atomic vapor. In analogy to the Pound-Drever-Hall method, which uses a cavity as a memory of the laser phase, this method uses atomic coherence (dipole oscillations) as a phase memory of the transmitting laser field.
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.

We stabilize an external-cavity diode laser near 369 nm for cooling Yb+ ions, using amplitude modulated polarization spectroscopy and a commercial PID feedback system. We achieve stable, low-drift locking with a standard deviation of measured laser frequency ∼ 400 kHz over 10 minutes, limited by the instantaneous linewidth of the diode laser.

The frequency of a laser can be stabilized via optical feedback from a stable reference cavity. (This may also be considered as using an extended laser resonator, being a kind of composite cavity.) Synchronization of two mode-locked lasers is possible via cross-phase modulation in a Kerr medium , in which the intracavity pulses of both lasers meet.
