Intra-cavity frequency doubling of an electrically pumped edge-emitting 980 nm laser diode with PPLN

摘要

The growing trend for laser-based projection displays makes intra-cavity frequency doubling (ICFD) of electrically and optically surface emitting diode lasers in the near IR region become more interesting [1-3]. In this letter, we demonstrate for the first time to our knowledge ICFD of an edge emitting laser diode using a periodically poled lithium niobate (PPLN) bulk crystal, which has the potential to be scalable to high production volumes and low costs with immense implication for industrial applications.
