Adjustable phase-locking of two Nd:glass ring laser beams

Mutual locking of two Nd:glass ring laser beams with any prescribed relative phases is shown. The two beams oscillate in the same optical cavity and locking is performed thanks to a pair of mutually matched spatial filters located in the Fourier planes of the cavity.
