Abstract
An electrical pumping vertical external-cavity surface-emitting laser (EP-VECSEL) device. The device may comprise a bottom contact, a first distributed Bragg reflector (DBR) disposed on the bottom contact, and an active region comprising a plurality of emitters, disposed on the first DBR configured to accept an electrical current at multiple emitters on the active region such that the multiple emitters produce a plurality of lasers. The multiple emitters may be configured to form a desired Hermite Gaussian (HG) mode shape. The device may further comprise a second DBR disposed on the active region and a top contact disposed on the second DBR. The top contact may be shaped such that the plurality of lasers are directed through the top contact. The device may further comprise an array output coupler disposed optically in line with the top contact such that the plurality of lasers are directed into the array output coupler.
