Abstract

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. Our new cavity design uses an external dichroic mirror coated for high reflectivity in the near-infrared range and transparent for blue light emission is used as output coupling mirror. These results demonstrate for the first time to our knowledge that stable ICFD is possible using telecom high power laser diodes with PPLN and that our model correlates with the experimental data. Further improvements are now possible through careful design of the lens used on the fast and slow axis beam waists and use of lower-temperature MgO-doped PPLN. This research could lead to disruptive lighting opportunities in laser-based projection displays.
