Abstract :
The optically pumped semiconductor (OPS) chip consists of two sections, both semiconductor alloys grown by MBE epitaxy. The top section is the gain medium and the bottom section is a high reflecting mirror that constitutes one of the ends of the cavity. The gain at 976 nm is provided by narrow layers of InGaAs quantum wells, the composition of the spacer layers is chosen such as to make them transparent to the laser wavelength, and strongly absorbent to the pump wavelength (around 800 nm).
