Fabrication process and power and lifetime characteristics of very-small-aperture laser
微小孔径激光器的工艺及器件功率和寿命特性分析

High output power very-small-aperture laser has been created on 650nm edge emitting laser diodes.The far-field output power is 0.4mW at the 25mA driving current,and the highest output power exceeds 1mW. The special fabrication process is described and the failure mechanism leading to the short lifetime of the devices is discussed.
