High power COD-free operation of 0.98 µm InGaAs/GaAs/InGaP lasers with non-injection regions near the facets

The authors demonstrate the catastrophic-optical-damage-free high-output-power operation of 0.98 µm InGaAs/InGaP/GaAs buried-ridge-structure lasers with non-injection regions near the facets. A maximum output power of 466 mW and fundamental operation at 100 mW were achieved.
