Low threshold three-segmented composite cavity structure GaAlAs/GaAs single-mode laser
A low threshold three-segmented composite cavity GaAlAs/GaAg laser is reported with a lowest CW threshold current of about 18 mA. It operates in stable single-mode, external differential quantum efficiency is 50-80% and the best linear relationship between light output and current remains up to 30 mW. Single frequency oscillation locking is achieved over the temperature range of around 5°C and the highest temperature for CW lasing is 117 ℃.
