Abstract
Low-threshold-current (20mA) 670nm multiquantum-well laser diodes (LDs ) for bar-code readers (BCRs) and laser pointers have been developed. A marked reduction in power consumption (40% lower than conventional b ulk LDs) and a maximum CW temperature of 110 degrees C have been reali sed simultaneously. Estimated lifetimes of more than 10000h, which is sufficient for both BCRs and laser pointers, were obtained at 5mW, 60 degrees C, with operating currents of less than 40mA.
