Abstract
A dermatological treatment device includes a handheld device body, and a laser control circuit housed in the device body and configured to generate laser radiation for delivery to a target area of tissue. The laser control circuit includes a multiple-emitter laser diode and a battery source. The multiple-emitter laser diode includes a monolithic stack of layers formed on a substrate, the monolithic stack of layers including a multiple-emitter region defining at least two emitter junctions, each emitter junction configured to emit a laser beam. The battery source provides current to the laser diode such that each of the at least two emitter junctions concurrently emits a laser beam, the at least two concurrently emitted laser beams forming a collective beam. The device delivers the collective beam to the target area of tissue to provide a dermatological treatment.
