Abstract: Generally, the disclosure describes a scanlaser with a fly''s eye lens array for discretized or digitalized beam steering via mode selection. In a scanlaser, a localized change in birefringence changes the Q of the associated laser cavity so that only certain modes can be sustained in the cavity. A scanlaser in accordance with this disclosure incorporates a fly''s eye lens array which selects only one of the latter modes for lasing in the cavity.
