Lau cavity and phase locking of laser arrays.
The Lau cavity is the self-imaging cavity with a phase corrector under the Lau reimaging condition. I propose the use of the Lau cavity to utilize both the Talbot and the Lau effects for phase locking one-dimensional and two-dimensional diode-laser arrays into a single-lobe coherent beam. Analyses on the self-reproducing of a coherent lasing field and the reimaging of initial incoherent radiation are given.
