532nm laser sources based on intracavity frequency doubling of multi-edge-emitting diode lasers

Intra-cavity frequency doubling (ICFD) of electrically and optically surface emitting diode lasers in the near IR region become more interesting [1-3] and will have an enormous impact in the display market. In this paper, Watts-level green laser is generated by ICFD of multi-emitters laser bar using a MgO-doped periodically poled lithium niobate (MgO: PPLN) bulk crystal, which has the potential to be scalable to high production volumes and low costs with immense implication for laser-based projection displays
