TLDR
In this article, a significant improvement in frequency doubling efficiency of a cw output of a GaAlAs laser diode was described, up to 0.72 mW of 421 nm power was generated by illuminating a KNbO3 crystal with a 270 mW diffraction-limited beam generated by an externally injection-locked laser dioder array, operating in a singlemode and single-far field lobe.Abstract:

Single lobe operation of a 40‐element laser array in an external ring laser cavity
Lew Goldberg,Joseph F. Weller +1 more
TL;DR: In this article, single-mode operation of a 40-element GaAlAs gain guided coupled stripe array emitting 500 mW cw was obtained in an external ring laser cavity, which is equivalent to self-injection locking of the array by its own output, which was first spatially filtered by a single mode fiber.
