title: Split-mode unstable resonator.
abstract: A novel class of unstable resonators is described in which the mode spatial distribution is altered within the resonator by a prism or axicon. In the particular configuration studied in this work, the resonator beam is separated into two halves by an intracavity reflecting prism. The conditions under which the two halves of the resonator become phase locked to form a coherent mode are studied experimentally and discussed in terms of laser injection locking.
