As one of the most efficient sources of near infrared radiation, semiconductor diode lasers play a crucial role in manufacturing, defense, and communications. Optimization of quantum well structures and the reduction of parasitic voltage losses have pushed electrical-to-optical power conversion efficiencies (PCEs) of stateof-the-art devices beyond 70%. This makes the semiconductor diode laser an attractive candidate for materials processing and laser pump applications.
