Abstract

We present laser results of OPS structures based on highly strained InGaAs quantum wells emitting at 1178nm and frequency doubled to produce high power, high beam quality laser radiation at 589nm. The laser architecture is the same as in our commercial offerings, allowing us to achieve the desired results with a system significantly simpler than alternative approaches.
