ABSTRACT:
A Coupled Multiple Output Resonator (CMOR) having two symmetric modules 10,20, is created by adding self-feedback (SFB) mirrors 104,106 aligned with apertures 100,102, in output scraper mirrors 14,24, respectively, to a conventional Multiple Output Resonator (MOR). The SFB mirrors re-inject a portion of the output beams 34,42 back into the resonator cavity as adjoint beams 108,110 which alter the modes of the system such that the CMOR only lases at desired modes where all the output beams 34,42 are in-phase. The CMOR provides substantially constant acceptable mode discrimination for more than 4 modules with only one SFB mirror per module and no additional external coupling paths between modules, thereby allowing the system to be scaled to any number of lasers without reduction of target intensity. Also, the SFB mirrors are small and are easily controlled to compensate for cavity mirror variations to maintain the desired mode discrimination.
