Published in: SPIE OPTO 2025 Authors: R. Ulkuniemi, A. Schramm, S. Talmila, M. Mähönen, L. Kuusela, T. Aho, J. Hämelahti, V. Vilokkinen, P. Sipilä, P. Uusimaa Visible red laser diodes are mostly based on AlGaInP material systems, grown on GaAs. The challenges in manufacturing of the diodes are found in thermal behavior, facet stability, and doping, which must be solved for reaching the best
