This study presents aluminum-free diode lasers that demonstrate high power conversion efficiency at 970 nm. Al-free active diode lasers, i.e. InGaAs(P)/InGaP/GaAs have superior power-conversion efficiency compared to conventional Al-containing devices due to their low differential series resistance and higher thermal conductivity.
