Abstract :
Improved TCSM lasers with antireflection coatings have been developed that operate in a stable zero-order mode to output powers of 80 mW CW. The devices operated in a stable single longitudinal mode to powers >65 mW. This is believed to be the highest single-mode power ever reported from an individual diode laser.
