Vertical external cavity surface emitting laser (vecsel) array

A vertical external-cavity surface-emitting laser (VECSEL) device (100) comprising:

• a. an active region (120) comprising a plurality of emitters, configured to accept a signal at two or more emitters of the plurality of emitters such that the two or more emitters produce a plurality of lasers, each emitter of the plurality of emitters comprising:
• i. a heat spreader component (121);
• ii. a VECSEL (122) disposed on the heat spreader component (121);
• iii. an intracavity heat spreader component (123) disposed at least partially within a cavity disposed in the VECSEL (122);
• iv. a frequency selection element (124) disposed parallel to and optically in line with the intracavity heat spreader component (123);
• v. one or more lenses (125) disposed parallel to and optically in line with the frequency selection element (124);
• and
• vi. an emitter output coupler (126) disposed parallel to and optically in line with the one or more lenses (125);
• wherein the two or more emitters are configured to form a desired Hermite Gaussian (HG) mode shape;
• and
• b. an array output coupler (160) disposed optically in line with the active region (120) such that the plurality of lasers are directed into the array output coupler (160).
